Description
The IR2153D(S) are an improved version of the
8 Lead PDIP
8 Lead SOIC
popular IR2155 and IR2151 gate driver ICs, and incor-
porates 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 providing comprehensive ESD protection on all pins.
