TD351

TD351 Advanced IGBT/MOSFET driver Features ■ 1.7 A sink / 1.3 A source (typ) current capability ■ Active Miller clamp feature ■ Two-level turn-off with adjustable level and delay ■ Input compatible with pulse transformer or optocoupler ■ UVLO protection ■ 2 kV ESD protection Applications ■ 1200 V 3-phase inverters ■ Motor control systems ■ UPS 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. Table 1.
