DESCRIPTION

The LM5100/LM5101 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 capable of operating with supply voltages up to

100V. The outputs are independently controlled with

CMOS input thresholds (LM5100) or TTL input

thresholds (LM5101). 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. This device is available in the standard

SOIC-8 pin and the WSON-10 pin packages.
