| PD-91800 IR2153Z Features * Floating channel designed for bootstrap operation Fully operational to +600V Tolerant to negative transient voltage dV/dt immune * Undervoltage lockout * Programmable oscillator frequency SELF-OSCILLATING HALF-BRIDGE DRIVER Product Summary VOFFSET Duty Cycle IO+/Vclamp Deadtime (typ.) 600V max. 50% 200 mA / 400 mA 15.6V 1.2 s f= * * * * 1 1.4 x (RT + 75) x CT Matched propagation delay for both channels Micropower supply startup current of 90 A. Shutdown function turns off both channels Low side output in phase with RT Description The IR2153Z 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 pulse current buffer stage and an internal deadtime designed for minimum driver crossconduction. 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.

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 CLAMP. 2 www.irf.com IR2153Z Static Electrical Characteristics VBIAS (VCC, VBS) = 12V, CL = 1000 pF, CT = 1 nF and TA = 25C unless otherwise specified. The VIN, VTH and IIN parameters are referenced to COM. The VO and IO parameters are referenced to COM and are applicable to the respective output leads: HO or LO.
