Description
The IR2153D(S) are an improved version of the
popular IR2155 and IR2151 gate driver ICs, and incorporates
a high voltage half-bridge gate driver with a front end oscillator similar to the industry standard CMOS
555 timer. The IR2153 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
