IR25603(S)PBF Self-Oscillating Half-Bridge Driver Features               Product Summary Floating channel designed for bootstrap operation Integrated 600 V half-bridge gate driver 15.6 V zener clamp on Vcc True micropower start up Tighter initial dead time control Low temperature coefficient dead time Shutdown feature (1/6th Vcc) on CT pin Increased undervoltage lockout Hysteresis (1 V) Lower power level-shifting circuit Constant LO, HO pulse widths at startup 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 VOFFSET 600 V max. Duty Cycle 50% Tr / Tf 80 ns / 40 ns VCLAMP 15.6 V Dead time (typ.) 1.2 µs Io+/Io- (typ.) 180 mA / 260 mA 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 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. 8 Lead SOIC 8 Lead PDIP Ordering Information Base Part Number Package Type IR25603SPBF Standard Pack Form Quantity SO8N Tube 95 IR25603SPBF SO8N Tape and Reel 2500 IR25603PBF PDIP8 Tube 50 1 www.irf.com © 2014 International Rectifier Orderable Part Number IR25603SPBF IR25603STRPBF IR25603PBF January 17, 2014 IR25603(S)PBF Typical Connection Diagram 2 www.irf.com © 2014 International Rectifier January 17, 2014 IR25603(S)PBF 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, all currents are defined positive into any lead. The thermal resistance and power dissipation ratings are measured under board mounted and still air conditions.
