Advance Information
SELF-OSCILLATING HALF-BRIDGE DRIVER
The MPIC2151 is a high voltage, high speed, self-oscillating power MOSFET and IGBT driver with both high side 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 from 10 to 600 volts.

TA -40 125 C Note 1: Because the MPIC2151 is designed specifically for off-line supply systems, this IC contains a zener clamp structure between the chip VCC and COM which has a nominal breakdown voltage of 15.6 V. 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 VCLAMP.
