Self-Oscillating Half-Bridge Driver
Ordering Information
Features
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
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.

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.

† This IC contains a zener clamp structure between the chip VCC and COM which has a nominal breakdown voltage of 15.6V. 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.
