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.
