TD350 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

TD350 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. 

TD350 also includes an IGBT desaturation 
protection and a FAULT status output.

TD350 is compatible with both pulse transformer 
and optocoupler signals.
