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.
