SNVS268B – MAY 2004 – REVISED DECEMBER 2014 LM5102 High-Voltage Half-Bridge Gate Driver With Programmable Delay
1 Features 3 Description The LM5102 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 floating high-side driver is capable
of working with supply voltages up to 100 V. The
outputs are independently controlled. The rising edge
of each output can be independently delayed with a
programming resistor. 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 control logic to the high
side gate driver. Undervoltage lockout is provided on
both the low side and the high side power rails. This
device is available in the standard VSSOP 10 pin and
the WSON 10 pin packages. 1 Drives Both a High-Side and Low-Side N-Channel …
