IR2153 Introduction
The IR2153 is an enhanced version of the widely-used IR2155 and IR2151 gate driver ICs, integrating a high-voltage half-bridge gate driver and a front-end oscillator, similar to the CMOS 555 timer. This improved design offers greater functionality and ease of use compared to its predecessors.
Notably, the IR2153 features a shutdown capability through the CT pin, allowing both gate driver outputs to be disabled via a low-voltage control signal. Additionally, it offers stable gate driver output pulse widths and improved noise immunity, achieved through lower di/dt and a 1V undervoltage lockout hysteresis, along with enhanced latch immunity and comprehensive ESD protection.

How to Use IR2153?
First, connect the power supply to the VCC pin of the IR2153. Simultaneously, connect the COM pin to ground. Next, select appropriate resistor (RT) and capacitor (CT) values, and connect them to the corresponding pins. These components will set the operating frequency of the IR2153. You can determine the desired oscillation frequency using the formula f=1.1/(RT×CT).
Then, connect the LO pin and HO pin to the required power switching devices, such as MOSFETs or IGBTs. After powering on the circuit, control the CT pin with a low voltage control signal to enable or disable the driver outputs. Use an oscilloscope to measure the output waveforms at the LO and HO pins to ensure they meet the expected frequency and duty cycle requirements.
