IR2152 - International Rectifier

IR2152 SELF-OSCILLATING HALF-BRIDGE DRIVER

The IR2152 is a high voltage, high speed, self-oscillating power MOSFET and IGBT driver with both high and low side referenced output channels. Proprietary HVIC and latch immune CMOS technologies enable ruggedized monolithic construction. The front end features a programmable oscillator which is similar to the 555 timer. The output drivers feature a high pul.
