The IR2153 IC is an improved version of the popular IR2155 and IR2151 gate driver ICs and incorporates a high voltage half-bridge gate driver with a front 8 Lead SOIC 8 Lead PDIP 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.
