Description
The IR2153(D)(S) are an improved version of the
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
8 Lead SOIC
8 Lead PDIP
has been designed into the C pin, so that both gate driver outputs can be disabled using a low voltage control
T
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 startup. Noise
CC
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.
