The full bridge features very low impedanceFETs with a typical RON (high side low side) of 0.3Ω resulting in high driving efficiency. The peak current ratingof 3.5A is limited by the overcurrent protection threshold(OCP). The peak current is defined as the maximum current the driver can provide for short transients. The maximum RMS current is 2A and is typically limited by thermalconsiderations. The 2ARMS capability refers to a standardJEDEC 4-layer board at 25 C ambient temperature. Thereal operating maximum current depends on the application thermal characteristic (PCB ground planes, heatsinks, ventilation, etc.). One Full H-Bridge with 36V Voltage Rating Total RDS(ON) (High Side Low Side): 300mΩ (typ)(TA 25 C) Current Ratings ( 25 C typ) IPEAK 3.5A IRMS 2AThe MAX22201/MAX22202/MAX22207 feature a non-dissipative and accurate integrated current sensing (ICS) andan embedded internal current drive regulation (CDR) circuit to monitor the current through a motor coil and limitthe peak output current. When the motor current exceedsthe current limit threshold, the full bridge enters a decaymode for a fixed off time (tOFF). For brushed motor driveapplications, the current drive regulation guarantees safeand reliable operation of the driver under normal conditions or during motor startup and stall conditions, and also reduces system power and supply bypassing requirements. A scaled copy of the internally sensed current isoutput to an external pin (ISEN). For more information onthese features, refer to the Detailed Description.All versions feature overcurrent protection (OCP), thermalshutdown (TSD), and undervoltage lockout (UVLO). Anopen-drain active-low fault indication pin (FAULT) is activated every time a fault condition is detected.The device is packaged into a tiny TDFN12 3mm x 3mmpackage. The small package footprint, the extremely highefficiency and the integrated accurate current sensingmake the MAX22201/MAX22202/MAX22207 an excellentchoice for space- and power-sensitive applications.Applications Brushed DC Motor Drive Stepper Motor Drive (One Phase Only) Latched Valves and Solenoids19-100898; Rev 1; 12/20 Configurable Current Drive Regulation (CDR) forLimiting Stall and Inrush Current Configurable Off Time (tOFF) for CDR (MAX22201only) Lossless Integrated Current Sensing (ICS) EliminatesExternal Bulky Resistors and Saves Power Current Sense Output (CSO) Function: A Replica ofthe Internally Sensed Current is Output on the ISENPin Current Drive Regulation Monitor (CDROUT)(MAX22207 only) Fault Indicator pin (FAULT) Fully Integrated Charge Pump Protections Overcurrent Protection for Each Individual Channel(OCP) Undervoltage Lockout (UVLO) Thermal Shutdown (TSD) T 165 C ESD Protection 8kV HBM (OUT1 and OUT2 Pins) Ultra-Small Package TDFN12 3mm x 3mmOrdering Information appears at end of datasheet.

MAX22201/MAX22202/MAX2220736V, 3.5A Brushed Motor Driver withIntegrated Current SenseDetailed DescriptionThe MAX22201/MAX22202/MAX22207 integrate one 36V, 3.5A peak full-bridge for motor driver applications. Thedevice can be used to drive one brushed DC motor. The full-bridge features very low-impedance FETs with a typical RON(high-side low-side) of 0.3Ω. The peak current of 3.5A is limited by the overcurrent protection (OCP) threshold. Thepeak current is defined as the maximum current the driver can provide for short transients. The maximum RMS currentis 2A and is typically limited by thermal considerations. The 2ARMS capability refers to a standard JEDEC 4-layer boardat 25 C ambient temperature. The actual operating maximum current depends on the application thermal characteristic(PCB ground planes, heat sinks, ventilation, etc.).The MAX22201/MAX22202/MAX22207 feature a nondissipative and accurate integrated current sensing (ICS) thatsenses the current flowing through low-side power FETs. This feature eliminates the need for external bulky andexpensive power resistors and results in significant space and power saving compared with mainstream applicationsbased on external power-sense resistors. An embedded internal current drive regulation (CDR) circuit regulates the peakoutput current effectively limiting the maximum inrush current during motor startup or a stall condition. The CDR currentlimit threshold (ITRIP) can be configured with an external standard resistor connected to pin ILIM. When the motor currentexceeds ITRIP, the full bridge enters in decay mode for a fixed off time (tOFF).In brushed motor drive applications, the current drive regulation not only guarantees safe and reliable operations for thedriver, but also reduces system power and supply bypassing requirements. A replica of the internally sensed current isoutput on the ISEN pin. By connecting an external standard resistor from this pin to GND, a voltage proportional to themotor current is generated. The voltage across this external resistor can be input into an external controller ADC whenthe motor-control algorithm requires the current/torque information. The user can select the resistor value so that thepeak voltage meets the ADC full-scale requirement.Three versions are available with various control interfaces. The MAX22201 and MAX22207 are controlled with two PWM logic inputs (IN1, IN2) resulting in 4 possible states:forward, reverse, brake (slow decay), and coast. Setting both inputs low for more than 2.2ms, the MAX22201 enterslow-power sleep mode. The MAX22201 features a user configurable off time that can be set by connecting an externalresistor to the ROFF pin. The MAX22202 features an ENBL/PHASE interface with an additional logic input pin (MODE) to select slow/fastdecay. A break condition longer than 2.2ms followed by a high-to-low transition of the MODE pin enters low-powersleep mode. The MAX22207 features a CDR monitor open-drain output that is asserted when the internal regulation loop takescontrol of the driver.All three versions feature overcurrent protection (OCP), thermal shutdown (TSD), and undervoltage lockout (UVLO)monitoring. An open-drain active-low fault indication pin (FAULT) is activated every time a fault condition is detected.Sleep Mode DescriptionMAX22201/MAX22207When both IN1 and IN2 inputs are low for longer than tSLEEP (2.2ms max), the MAX22201 enters low-power sleepmode. In this mode, outputs are three-stated and the device current consumption is ISLEEP (6.5μA max). If the device ispowered up with both inputs low, sleep mode is immediately entered. To exit Sleep mode and power on the device, driveIN1 and IN2 high for at least 400μs.MAX22202 OnlyThe MAX22202 enters Sleep mode if the MODE pin is maintained high (brake/slow decay) for longer than tSLEEP (2.2msmax) and afterwards is driven low. In this mode, outputs are three-stated and the device current consumption is ISLEEP(10μA max). After power up, when MODE 0, the device immediately enters in Sleep mode. To exit Sleep mode andpower up the device, drive MODE high for at least 400μs (tON max).www.maximintegrated.comMaxim Integrated 10
MAX22201/MAX22202/MAX2220736V, 3.5A Brushed Motor Driver withIntegrated Current SenseMotor Drive Control: Use CasesThe MAX22201/MAX22202/MAX22207 provide flexibility and support different use cases. The most common use casesare described below.1. PWM With Internal Current Drive RegulationIn this use case, the regulation current limit (ITRIG) is set above the normal operating current (INOM) with the purposeof limiting the inrush current at motor startup. Afterwards, the external controller controls the motor by means of PWMsignals for speed or position control. Normally brake (slow decay) is used during the off-phase as it results in low rippleand power consumption. However, fast- or mixed-decay control can also be implemented.2. PWM Without Internal Current Drive RegulationIf the internal current regulation is not needed, a 14kΩ should be connected on the ILIM pin. In this configuration, theinternal current drive regulation is disabled and the MAX22201/MAX22202/MAX22207 provide the maximum current(3.5A), which can only be sustained for a short period of time. In this use case, an external controller controls the motorby means of PWM signals for speed or position control. Normally brake (slow decay) is used during the off-phase as itresults in low ripple and power consumption. However, fast- or mixed-decay control can also be implemented. Since theinternal limiter is disabled, if the current is not properly controlled, it can reach the overcurrent protection threshold or thejunction temperature can rise above the thermal protection threshold causing a fault condition and stress the device.3. Internal Current Regulation only (no PWM)In this use case, no PWM control signal is applied on logic inputs. These logic inputs are used just to enable/disablethe full bridge or to set the current direction. The internal current regulation circuit controls the output current dependingon the resistor value at ILIM. The torque control is simply implemented by setting the desired ITRIP current. Thecorrespondent motor speed results from the torque-speed characteristic of the motor. The user can also consider varyingthe current dynamically by changing the resistor connected to ILIM.4. PWM Control Based on the ISEN CurrentSimilar to use cases 1 and 2, the driver is controlled with PWM signals. However, the MCU control algorithm requiresfeedback in the form of the motor current. To support this use case, the MAX22201/MAX22202/MAX22207 ISEN pinsoutput a current proportional to the output current. A resistor connected to the ISEN pin makes the current-to-voltageconversion and can be monitored by the controller ADC. The internal current drive regulation can be either enabled (case1) or disabled (case 2).Bridge ControlMAX22201/MAX22207The bridge driver is controlled by two logic inputs (IN1 and IN2) as shown in Table 1Table 1.

Generally, Cole Hersee heavy duty 12V non-illuminated* toggle and rocker switches can be used at higher voltage but lower current. Example: By calculation, 25A 12V switch will derate to 8.3A at 36V, or 12.5 at 24V. This calculated de-rating gives a conservative result. 25A at 12V toggle switches* can actually be used at 15A at 24V, and 10A at 36V.
