What is IR2153?

The IR2153 includes a high voltage half-bridge gate driver with a front-end oscillator comparable to the industry-standard CMOS 555 timer and is an enhanced version of the popular IR2155 and IR2151 gate driver ICs. The IR2153 has more features and is more user-friendly than prior ICs. The CT pin features a shutdown capability that allows both gate driver outputs to be disabled using a low voltage control signal. Furthermore, after the rising under-voltage lockout threshold on VCC is achieved, the gate driver output pulse widths are the same, resulting in a more stable frequency vs time profile at startup.

Where to use IR2153

The IR2155 and IR2151 gate driver ICs have been upgraded in the IR2153. The IR2153 has more features and is more user-friendly than prior ICs. By decreasing the peak di/dt of the gate drivers and raising the under-voltage lockout hysteresis to 1V, noise immunity has been greatly enhanced. Finally, the device's latch immunity has been maximized, and all pins have been provided with extensive ESD protection.

Because this IC is a half-bridge gate driver, it can be utilized in a variety of applications such as DC-DC power supply, inverters, motor drivers, solenoid drivers, and high side MOSFET drivers for protection relay and motor driver applications.
