TD351 Datasheet, PDF (1/12 Pages) STMicroelectronics – Advanced IGBT/MOSFET Driver

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.
