3 Description

The EMB1412 MOSFET gate driver provides high

peak gate drive current in 8-lead exposed-pad

VSSOP package, 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 7-A 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 EMB1412

provides both inverting and non-inverting inputs to

satisfy requirements for inverting and non-inverting

gate drive with a single device type.
