Description

This device is an advanced gate driver for IGBT

and power MOSFETs. Control and protection

functions are included and allow the design of

high reliability systems.

The innovative active Miller clamp function

eliminates the need for negative gate drive in

most applications and allows the use of a simple

bootstrap supply for the high side driver.

The 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 conditions.

The same delay is applied at turn-on to prevent

pulse width distortion.

SO-8

The TD351 is compatible with both pulse

transformer and optocoupler signals.
