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.
