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.
