LM5101 - High Voltage High Side and Low Side Gate Driver

Download the LM5101 datasheet PDF. This datasheet also covers the LM5100 variant, as both devices belong to the same high voltage high side and low side gate driver family and are provided as variant models within a single manufacturer datasheet.

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.

LM5100/LM5101 High Voltage High Side and Low Side Gate Driver January 2004 LM5100/LM5101 High Voltage High Side and Low Side Gate Driver General 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.
