Features

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 C T 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 V CC 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.
