Order this document by MPIC2151/D SEMICONDUCTOR TECHNICAL DATA Power Products Division 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. • • • • • • SELF–OSCILLATING HALF–BRIDGE DRIVER 8 1 Floating Channel Designed for Bootstrap Operation Fully Operational to +600 V Tolerant to Negative Transient Voltage P SUFFIX PLASTIC PACKAGE CASE 626–05 dV/dt Immune Undervoltage Lockout Programmable Oscillator Frequency: f • • + 1.4 (RT )1 75W) CT 8 Matched Propagation Delay for Both Channels 1 Low Side Output In Phase with RT PRODUCT SUMMARY VOFFSET D SUFFIX PLASTIC PACKAGE CASE 751–05 (SO–8) 600 V MAX Duty Cycle 50% VOUT 10 – 20 V tr/f (typical) 120 & 60 ns Deadtime (typical) 1.2 µs PIN CONNECTIONS VCC 1 8 VB RT 2 7 HO CT 3 6 VS COM 4 5 LO (TOP VIEW) ORDERING INFORMATION This document contains information on a new product.

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.
