Description
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.

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.
