IR51H310集成电路（IC）的全半桥驱动器规格书PDF中文资料

描述 Description

The IR51H310 is a high voltage, high speed, selfoscillating half-bridge. Proprietary HVIC and latch immune CMOS technologies, along with the HEXFET® power MOSFET technology, enable ruggedized single package construction. The front-end features a programmable oscillator which functions similar to the CMOS 555 timer. The supply to the control circuit has a zener clamp to simplify offline operation.
