600 V Self Oscillating Half Bridge Gate Driver IC IR25603

The IR25603 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
under-voltage 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.

Model performance :
- Static Electrical Characteristics and Dynamic Electrical Characteristics
are modeled with the typical values from the datasheet.
- Temperature effects are not modeled

The following features have been modeled :
- Switching Characteristics such as propagation delay, peak currents
- Under-voltage lockout
