Description
The IR21531(D)(S) are an improved version of the
popular IR2155 and IR2151 gate driver ICs, and in-
corporates a high voltage half-bridge gate driver with a front end oscillator similar to the industry standard
CMOS 555 timer. The IR21531 provides more functionality and is easier to use than previous ICs. 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. Noise immunity has been improved significantly, both by lowering the peak di/dt of the gate drivers,
and by increasing the undervoltage lockout hysteresis to 1V. Finally, special attention has been payed to
maximizing the latch immunity of the device, and providing comprehensive ESD protection on all pins.
