Product Description

The IR21531SPBF is a self-oscillating Half-bridge Gate Driver IC incorporates a high voltage half-bridge gate driver with a front end oscillator similar to the industry standard CMOS 555 timer. The IC provides more functionality and is easier to use. 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 improved significantly, both by lowering the peak DI/DT of the gate driver and by increasing the under-voltage lockout hysteresis to 1V.
True micro power start-up
Tighter initial dead-time control
Low temperature coefficient dead time
Shutdown features on CT pin
Lower power level-shifting circuit
Constant LO, HO pulse widths at start-up
Low side output in phase with RT
Excellent latch immunity on all inputs and outputs
Finally special attention has been paid to maximizing the latch immunity of the device and providing comprehensive ESD protection all pins.
