Description
The IR2154 is an improved version of the popular
IR2152 gate driver IC, and incorporates a high voltage
half-bridge gate driver with a front end oscillator simi-
lar to the industry standard CMOS 555 timer. The
IR2154 provides more functionality and is easier to use
than previous ICs. A shutdown feature has been de-
signed 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 immu-
nity 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.
