IR2135SPBF is a isolated type gate driver IC designed to drive pulse width modulated (PWM) high power bipolar inverter applications. It is based on an advanced control and protection circuitry which provides a high reliability and safe operation. The device is designed to drive N-channel MOSFETs and IGBTs up to 3A current. The operating voltage range is from 8 to 22V.

This device mainly consists of an analog input section, a logic section, an oscillator section, a power section and a protection section. The analog input section includes two analog inputs labeled as A1 and A2. A1 is used to adjust the gate drive voltage and A2 is used to adjust the base current. The logic section consists of an enable pin, a shutdown pin, a watchdog pin and an error pin. The enable pin is used to initiate the gate driver operation while the shutdown pin is used to stop the gate driver operation. The watchdog pin is used to prevent the gate driver from being stuck in an undesired state and the error pin is used to monitor the output current of the gate driver.

The oscillator section includes an internally generated oscillator which is used to control the switching frequencies of the gate driver. This oscillator is adjustable from 1kHz to 4kHz. The power section includes a 5V output which is used to supply power to other components and a 3.3V output which is used to supply power to the rest of the IC. The protection section includes a diode bridge which is used to protect the output from any overcurrent conditions.

The main function of IR2135SPBF is to provide a high-speed, high-precision, reliable gate drive for bipolar inverters. The device is designed to work with a PWM frequency up to 4kHz, which makes it ideal for applications requiring high-frequency operation. It also offers an adjustable gate drive voltage and base current to ensure optimal performance according to the specific application. Furthermore, the device has an overcurrent protection and a watchdog pin to prevent the gate driver from being stuck in an undesired state. The device is also highly reliable and provides long-term stability and robust performance even in harsh environments.

Overall, IR2135SPBF is an ideal choice for driving N-channel MOSFETs and IGBTs up to 3A current in high-power bipolar inverter applications. It delivers high-speed, high-precision, reliable and safe gate drive operation even in harsh environments which makes it an ideal choice for applications requiring high-power gate drive operation.
