Preliminary IR25603(S)PBF Self-Oscillating Half-Bridge Driver Features Product Summary  Floating channel designed for bootstrap operation V 600 V max.  Integrated 600 V half-bridge gate driver OFFSET  15.6 V zener clamp on Vcc Duty Cycle 50%  True micropower start up  Tighter initial dead time control T / T 80 ns / 40 ns r f  Low temperature coefficient dead time  Shutdown feature (1/6th Vcc) on CT pin VCLAMP 15.6 V  Increased undervoltage lockout Hysteresis (1 V) Dead time (typ.) 1.2 µs  Lower power level-shifting circuit  Constant LO, HO pulse widths at startup Io+/Io- (typ.) 180 mA / 260 mA  Lower di/dt gate driver for better noise immunity  Low side output in phase with RT  Excellent latch immunity on all inputs and outputs  ESD protection on all leads Package Options Description The IR25603(S) incorporates a high voltage half-bridge gate driver with a front end oscillator similar to the industry standard CMOS 555 timer. A shutdown feature has been designed into the CT pin, so that both gate driver outputs can be disabled using a low voltage control signal. In addition, the gate driver output pulse widths are the same once the rising undervoltage lockout threshold on Vcc has been reached, resulting in a more stable profile of frequency 8 Lead SOIC 8 Lead PDIP vs time at startup. Special attention has been paid to maximizing the latch immunity of the device and providing comprehensive ESD protection on all pins.

Please note that this supply pin should not be driven by a DC, low impedance power source greater than the VCLAMP specified in the Electrical Characteristics section. †† Care should be taken to avoid output switching conditions where the VS node flies inductively below ground by more than 5V. ††† Enough current should be supplied to the VCC pin of the IC to keep the internal 15.6V zener diode clamping the voltage at this pin. 3 www.irf.com © 2014 International Rectifier January 17, 2014
