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 C 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

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.
