IR2153 Self Oscillating Half Bridge Driver IC

IR2153 is a self-oscillating 600V half-bridge IGBT and MOSFET driver IC with a typical 0A source and 0a sink current. It is the improved version of the popular IR2155 and IR2151 gate driver IC and incorporates a high voltage half-bridge gate driver IC with a front end oscillator similar to industry-standard CMOS 555 timer. The device includes a shutdown feature 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.
