TD352IDT STMicroelectronics

TD352 Advanced IGBT/MOSFET driver Features 1.7 A sink / 1.3 A source (typ) current capability Active Miller clamp feature Desaturation detection Adjustable turn-on delay SO-8 UVLO protection 2k V ESD protection Applications 1200 V 3-phase inverter Motor control systems UPS Description This device is an advanced gate driver for IGBTs 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 TD352 includes an adjustable turn-on delay. This feature can be used to implement reliable deadtime between high and low sides of a half bridge. An external resistor and capacitor are used to provide accurate timing. Table 1.
