概述

Description

LM5101ASD/NOPB is TI’s high-voltage dual gate driver designed to drive the high-side and low-side N‑channel MOSFETs in a half-bridge. It uses a bootstrap supply to drive the high-side gate and provides independent drive signals for the two transistors, plus fault protection.
Key features (typical):
- Bootstrap high-side and low-side gate drive
- Wide high-side operating range (suitable for high-voltage applications)
- Undervoltage lockout, shoot-through protection, and fault/flag outputs
- Pb-free option (NOPB) and specific package variant (ASD)
Typical applications:
- Motor drives, power converters, switch-mode power supplies, and DC-DC converters
Note: Packaging codes (ASD) refer to the device package; NOPB denotes Pb-free. For exact electrical specs, timing, and recommended operating conditions, consult the TI LM5101 datasheet and TI application notes.

Features

Here are the key features of the LM5101ASD/NOPB (gate driver for N‑channel MOSFETs):
- High-side and low-side gate drive for half-bridge configurations
- 100-V bus operation with bootstrap high-side drive
- Independent logic inputs with an enable/shutdown control
- Bootstrap capacitor supply for the high-side driver
- UVLO protection on VCC and VB to prevent mis-drive
- Shoot-through protection with dead-time control
- Fast gate transitions with high peak drive capability (several amperes)
- Fault/diagnostic reporting output (status/fault indication)
- Pb-free, RoHS-compliant packaging (NOPB variant; ASD denotes the package code)
Note: For exact electrical specs (drive strengths, UVLO thresholds, timing, and package details), please refer to the datasheet.

Pinout

- Pin count: 8 pins (8-pin package, e.g., SOIC-8/D package).
- Function: Dual high-side/low-side gate driver with bootstrap supply. It provides HO and LO outputs to independently drive N‑channel MOSFETs in a half-bridge or buck converter, using inputs HIN/LIN (and SD/EN), with VB–VS bootstrap and UVLO features.
