LM5100/LM5101
High Voltage High Side and Low Side Gate Driver
General Description
The LM5100/LM5101 High Voltage Gate Drivers are de-
signed 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 LLP-10 pin packages.
