3A, 2A and 1A High Voltage High-Side and Low-Side

Gate Drivers

General Description

Features

n Drives both a high-side and low-side N-Channel

MOSFETs

The LM5100A/B/C and LM5101A/B/C High Voltage Gate

Drivers are designed to drive both the high-side and the

low-side N-Channel MOSFETs in a synchronous buck or a

half-bridge configuration. The floating high-side driver is ca-

pable of operating with supply voltages up to 100V. The “A”

versions provide a full 3A of gate drive while the “B” and “C”

versions provide 2A and 1A respectively. The outputs are

independently controlled with CMOS input thresholds

(LM5100A/B/C) or TTL input thresholds (LM5101A/B/C). 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. Under-voltage lockout is provided on

both the low-side and the high-side power rails. These de-

vices are available in the standard SOIC - 8 pin and the LLP

- 10 pin packages.

n Independent high and low driver logic inputs

n Bootstrap supply voltage up to 118V DC

n Fast propagation times (25 ns typical)

n Drives 1000 pF load with 8 ns rise and fall times

n Excellent propagation delay matching (3 ns typical)

n Supply rail under-voltage lockout

n Low power consumption

n Pin compatible with HIP2100/HIP2101

Typical Applications

n Current Fed push-pull converters

n Half and Full Bridge power converters

n Synchronous buck converters

n Two switch forward power converters

n Forward with Active Clamp converters

Package

n SOIC-8

n LLP-10 (4 mm x 4 mm)
