Description
The IR2152 is a high voltage, high speed, self­oscillating 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 pulse current buffer stage and an internal deadtime designed for minimum driver cross-conduction. Propa­gation delays for the two channels are matched to sim­plify use in 50% duty cycle applications. The floating channel can be used to drive an N-channel power MOSFET or IGBT in the high side configuration that operates off a high voltage rail up to 600 volts.

Absolute Maximum Ratings
Absolute Maximum Ratings indicate sustained limits beyond which damage to the device may occur. All voltage param­eters are absolute voltages referenced to COM. The Thermal Resistance and Power Dissipation ratings are measured under board mounted and still air conditions.

structure between the chip VCC and COM which has a nominal breakdown voltage of 15.6V. Therefore, the IC supply voltage is normally derived by forcing current into the supply lead (typically by means of a high value resistor connected between the chip VCC and the rectified line voltage and a local decoupling capacitor from VCC to COM) and allowing the internal zener clamp circuit to determine the nominal supply voltage. There­fore, this circuit should not be driven by a DC, low impedance power source of greater than V
