Design LM25101
SNVS859C – JULY 2012 – REVISED SEPTEMBER 2016 LM25101 3-A, 2-A, and 1-A 80-V Half-Bridge Gate Drivers
1 Features 3 Description The LM25101 high-voltage gate driver is designed to
drive both the high-side and the low-side N-Channel
MOSFETs in a synchronous buck or a half-bridge
configuration. The A version provides a full 3-A of
gate drive while the B and C versions provide 2-A
and 1-A, respectively. The outputs are independently
controlled with TTL input thresholds. An integrated
high voltage diode is provided to charge the high-side
gate drive bootstrap capacitor. A robust level shifter
operates at high speed while consuming low power
and providing clean level transitions from the control
logic to the high-side gate driver. Undervoltage
lockout is provided on both the low-side and the highside power rails. 1 Independent High and Low Driver Logic Inputs
Bootstrap Supply Voltage up to 100-V DC
Drives Both a High-Side and Low-Side N-Channel …
