Where to use IR2153 MOSFET Gate Driver

The IR2153 is an improved version of the popular IR2155 and IR2151 gate driver ICs. 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 start-up. Noise 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 paid to maximizing the latch immunity of the device, and providing comprehensive ESD protection on all pins.

As this IC is a half-bridge gate driver IC that can be used in many different applications like DC-DC power supplies, Inverters, motor driver, solenoid river, high side MOSFET drivers can be used for protection relay power distribution and motor driver applications.
