IRS44273LDescriptionThe IRS44273L is a low voltage, power MOSFET and IGBT non-inverting gate driver. Proprietary latch immuneCMOS technologies enable ruggedized monolithic construction. The logic input is compatible with standardCMOS or LSTTL output. The output driver features a current buffer stage.3www.irf.com 2015 International RectifierJanuary 15, 2015

IRS44273LAbsolute Maximum RatingsAbsolute maximum ratings indicate sustained limits beyond which damage to the device may occur. The devicemay not function or not be operable above the recommended operating conditions and stressing the parts tothese levels is not recommended. In addition, extended exposure to stresses above the recommended operatingconditions may affect device reliability. All voltage parameters are absolute voltages referenced to COM. Thethermal resistance and power dissipation ratings are measured under board mounted and still air conditions.DefinitionSymbolMinMaxVCCFixed supply voltage-0.325VOOutput voltage-0.3VCC 0.3Logic input voltagePackage power dissipation @ TA 25 CThermal resistance, junction to ambientJunction temperatureStorage temperatureLead temperature (soldering, 10 seconds)-0.3———-55—VCC 0.3250191150150300VINPDRthJATJTSTLUnitsVmW C/W CRecommended Operating ConditionsFor proper operation, the device should be used within the recommended conditions.
