ALM2402-Q1 operates with single or splitpower supplies from 5.0 V to 16 V and can output upto 400 mA DC.1 High Output Current Drive: 400 mA Continuous(Per Channel)– Op-amp With Discrete Power Boost BufferReplacementWide Supply Range for Both Supplies (up to 16 V)Over Temperature ShutdownCurrent LimitShutdown Pin for Low Iq ApplicationsStable with Large Capacitive Loads (up to 3 µF)Zero Crossover DistortionQualified for Automotive ApplicationsAEC-Q100 Qualified With the Following Results:– Device Temperature Grade 1: –40 C to 125 CAmbient Operating Temperature Range– Device HBM Classification Level H2 (DRR)– Device CDM Classification Level C5 (DRR)Low Offset Voltage: 1 mV (typ)Internal RF/EMI FilterAvailable in 3.00 mm x 3.00 mm 12 Pin WSON(DRR) With Thermal Pad2 Applications Each op-amp includes over-temperature flag/shutdown. It also includes separate supply pins for eachoutput stage that allow the user to apply a lowervoltage on the output to limit the Voh and henceforththe on-chip power dissipation.The ALM2402 is packaged in a 12 pin leadless DRRpackage and 14 pin leaded HTSSOP (preview). Bothinclude a thermally conductive power pad thatfacilitates heat sinking. The very low thermalimpedance of these packages enable optimal currentdrive with minimal die temperature increase.Providing customers with the ability to drive highcurrents in harsh temperature conditions. Maximumpower dissipation can be determined in the figurebelow.Device Information(1)PART NUMBERPACKAGEALM2402-Q1Large Capacitive Loads– Cable Shields– Reference Buffers– Power-FET/IGBT Gates– Super CapsTracking LDOInductive Loads– Resolvers– Bipolar DC & Servo Motors– Solenoids & ValvesBODY SIZE (NOM)SON (12)3.00 mm x 3.00 mmHTSSOP (14)5.00 mm x 4.40 mm(1) For all available packages, see the orderable addendum atthe end of the data sheet.4 Simplified SchematicV CC OUTMaximum Power Dissipation vs Temperature OPAMPVCCIN1 5VCC O1 ½ALM2402OUT1IN1OTF1GNDAllowable Power Dissipation 201401An IMPORTANT NOTICE at the end of this data sheet addresses availability, warranty, changes, use in safety-critical applications,intellectual property matters and other important disclaimers.

These are stress ratingsonly, and functional operation of the device at these or any other conditions beyond those indicated under "recommended operatingconditions" is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.All voltage values are with respect to the GND/substrate terminal, unless otherwise noted.Maximum power dissipation is a function of TJ(max), θJA, and TA. The maximum allowable power dissipation at any allowable ambienttemperature is PD (TJ(max) – TA)/θJA. Operating at the absolute maximum TJ of 150 C can affect reliability.7.2 Thermal InformationALM2402Q1THERMAL METRIC (1)DRR (SON)PWP (HTSSOP)12 Pins14 PinsUNITθJAJunction-to-ambient thermal resistance39.246.5 C/WθJCtopJunction-to-case (top) thermal resistance34.533.0 C/WθJBJunction-to-board thermal resistance15.027.6 C/WψJTJunction-to-top characterization parameter0.31.5 C/WψJBJunction-to-board characterization parameter15.227.4 C/WθJCbotJunction-to-case (bottom) thermal resistance4.22.2 C/W(1)For more information about traditional and new thermal metrics, see the IC Package Thermal Metrics application report, SPRA953.7.3 ESD RatingsVALUEV(ESD)(1)(2)4Electrostatic dischargeHuman-body model (HBM), per ANSI/ESDA/JEDEC JS-001 (1) 2000Charged-device model (CDM), per JEDEC specification JESD22- DRRC101 (2)PWP 750UNITV 250JEDEC document JEP155 states that 500-V HBM allows safe manufacturing with a standard ESD control process.
