Description
The IR21531(D)(S) are an improved version of the
popular IR2155 and IR2151 gate driver ICs, and in-
8 Lead PDIP
8 Lead SOIC
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 pin, so that both gate driver outputs can be disabled using a low voltage
T
control signal. In addition, the gate driver output pulse widths are the same once the rising undervoltage
lockout threshold on V
has been reached, resulting in a more stable profile of frequency vs time at
CC
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.

Absolute Maximum Ratings
Absolute maximum ratings indicate sustained limits beyond which damage to the device may occur. All voltage param-
eters are absolute voltages referenced to COM, all currents are defined positive into any lead. The thermal resistance and
power dissipation ratings are measured under board mounted and still air conditions.
