3 Description
The SM74101 MOSFET gate driver provides high
peak gate drive current in the tiny WSON-6 package
(SOT23 equivalent footprint), with improved power
dissipation required for high frequency operation. The
compound output driver stage includes MOS and
bipolar transistors operating in parallel that together
sink more than 7A peak from capacitive loads.
Combining the unique characteristics of MOS and
bipolar devices reduces drive current variation with
voltage and temperature. Under-voltage lockout
protection is provided to prevent damage to the
MOSFET due to insufficient gate turn-on voltage. The
SM74101 provides both inverting and non-inverting
inputs to satisfy requirements for inverting and non-
inverting gate drive with a single device type.
