IRS44273L MOSFET Gate Drivers Infineon IRS44273L MOSFET gate drivers are simple solution IGBT and MOSFET gate drives, offering 1.5A (typical) sink and source capability, fast switching performance and integrated under-voltage lockout protection with minimal board space requirements. These ICs offer the highest available drive current for a low-side driver in an SOT-23-5L package enabling designers to use in place of larger SO-8 devices to significantly reduce solution size. With two output pins on either side of their packages, IRS44273L driver ICs simplify system design by offering layout flexibility. Infineon IRS44273L MOSFET gate drivers feature non-inverted inputs and are compatible with CMOS and LSTTL controllers.
