LM5114AMFX/NOPB

Overview

The LM5114AMFX/NOPB is a single low-side MOSFET gate driver manufactured by Texas Instruments, housed in an SOT-23-6 surface-mount package. It operates within a supply voltage range of 4 V to 12.6 V and delivers a peak output current of 7.6 A. The device features controllable rise and fall times, with typical values of 3.2 ns for rising and 8 ns for falling edges. Maximum propagation delays are specified at 36 ns for both turn-on and turn-off states. It supports TTL logic inputs and functions reliably across an extended temperature range from -40°C to +125°C.

Feature Summary
