IR25603SPBF

IR25603(S)PBF Features Self-Oscillating Half-Bridge Driver 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 Duty Cycle Tr / Tf VCLAMP Dead time (typ.) Io+/Io- (typ.) 600 V max. 50% 80 ns / 40 ns 15.6 V 1.2 µs 180 mA / 260 mA Description Package Options 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 IR25603SPBF ...
