IR2153PBF

100.00

The IR2153D(S) gate driver IC is an improved version of the popular IR2155 and IR2151 gate driver ICs, and it includes a high voltage half-bridge gate driver as well as a front end oscillator similar to the industry standard CMOS555 timer. The IR2153 has more functionality and is simpler to use than previous integrated circuits. The CT pin has a shutdown feature that allows both gate driver outputs to be disabled with a low voltage control signal. Furthermore, once the rising under voltage lockout threshold on VCC is reached, the gate driver output pulse widths are the same, resulting in a more stable frequency vs time profile at startup. Noise immunity has been significantly improved by lowering the gate drivers’ peak di/dt and increasing the under voltage 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.
