Description
Key points:
- Two independent drive channels with gate-drive current capability for rapid switching.
- Bootstrap-based high-side drive (for high-side MOSFETs) plus a low-side drive path.
- Built-in protections (e.g., undervoltage lockout, fault protection) and enable control for safe operation.
- Suitable for applications like DC-DC converters, motor drives, synchronous buck/boost converters, and bridge/topology power stages.
- -NOPB denotes RoHS-compliant, lead-free packaging; -MX refers to the specific TI package variant.
In short, it’s a compact, fast gate driver for driving dual MOSFET bridges in power electronics, with protections and RoHS-compliant packaging.

Pinout
- Function: Dual high-side/low-side MOSFET gate driver with a bootstrap supply. Provides HO (high-side) and LO (low-side) outputs to drive a half-bridge, controlled by IN with an SD shutdown input. VB/V S serve as the high-side floating supply and return; VCC/GND power the logic. Includes protections (UVLO, shoot-through) as typical.
Manufacturer
- What kind of company: An American multinational semiconductor company that designs and manufactures analog, mixed-signal, and embedded processing ICs, serving automotive, industrial, consumer electronics, and communications markets. Headquartered in Dallas, Texas.
Application
- Gate driver for high-side/low-side N‑channel MOSFETs in buck, boost, and buck-boost converters (including multi‑phase and synchronous rectification)
- Point‑of‑load, telecom and data-center power supplies
- Automotive and industrial DC‑DC power electronics
- Half‑bridge motor drives for BLDC/stepper motors
- Isolated or non‑isolated switching power stages needing fast switching, dead‑time control and protection features
