Description

The TD350E device is an advanced gate driver

for IGBTs 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 device 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 set in the two-level turn-off

feature is applied at turn-on to prevent pulse width

distortion.

The device also includes IGBT desaturation

protection and a FAULT status output, and is

compatible with both pulse transformer and

optocoupler signals.
