TD351中文资料先进的IGBT/MOSFET驱动器数据手册ST规格书

描述 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.

The TD351 is compatible with both pulse transformer and optocoupler signals.
