LM5102
High Voltage Half-Bridge Gate Driver with Programmable
Delay
General 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 float-
ing high-side driver is capable of working with supply volt-
ages up to 100V. The outputs are independently controlled.
The rising edge of each output can be independently de-
layed with a programming resistor. An integrated high volt-
age 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.
Under-voltage lockout is provided on both the low side and
the high side power rails. This device is available in the
standard MSOP-10 pin and the LLP-10 pin packages.
