IR44272L

Overview

For new designs, we recommend IRS44273L

Low Side Driver IC with typical 1.7 A source and 1.5 A sink currents in 5 Lead SOT23 package for IGBTs and MOSFETs.

IR44272L is a low-voltage, wide VCC range, non-inverting gate driver. Proprietary latch immune CMOS technologies enable ruggedized monolithic construction. The logic input is compatible with standard CMOS or LSTTL output. The output driver features a current buffer stage. The design also includes an enable input with internal pull up.
