TD351

Advanced IGBT/MOSFET Driver

s 1A sink / 0.75A source min. gate drive

s Active Miller clamp feature

s Adjustable and accurate two steps turn-off

level and delay

s Input compatible with pulse transformer or

optocoupler

s UVLO protection

s 2kV ESD protection

Description

TD351 is an advanced gate driver for IGBT and

power MOSFET. Control and protection functions

are included and allow the design of high reliability

systems

Innovative active Miller clamp function avoids the

need of negative gate drive in most applications

and allows the use of a simple bootstrap supply

for the high side driver

TD351 includes a two-level turn-off feature with

adjustable level and delay. This function protects

against excessive overvoltage at turn-off in case

of overcurrent or short-circuit condition. Same

delay is applied at turn-on to prevent pulse width

distortion.

TD351 is compatible with both pulse transformer

and optocoupler signals.
