The IR2135 is an integrated, high-performance gate driver that operates with both bipolar and high-side MOSFET/IGBT power switches. IR2135 is suitable for use in a variety of applications including motor control, switch-mode power supplies, and high power amplifiers. This driver has many features and benefits, including low-side MOSFET/IGBT options, adjustable switching frequency, automatic shoot-through protection, adjustable current handling capabilities and various thermal protection features.

IR2135 is especially suitable for high-current, large-area motor applications where the motor power is located both horizontally and vertically. It is capable of controlling single, two and three-phase motors, and is designed for very low EMI and power losses, high power density and high temperature applications in an exceptionally compact package.

The IR2135 gate driver has a host of features that enable it to maximize efficiency, process scalability and cost savings. The IR2135 includes full protection features to protect the gate-driver and power MOSFETs/IGBTs, such as automatic shoot-through protection, over-current protection, over-voltage protection, temperature protection and protection flags. In addition, it offers adjustable pre-bias, delay and dead-time, fast switching frequency selection, output current selection and low-side MOSFET/IGBT options. The IR2135 also has an integrated charge pump for high voltage start-up, and an adjustable dead-time to minimize shoot-through.

The IR2135 gate driver ICs are specifically designed for high-power and high-temperature applications, which requires less switching frequency, current and voltage losses, and guaranteed protection for the power MOSFETs or IGBTs. The IR2135 has built in protection for power switches, adjustable current handling capabilities and adjustable switching frequency, along with adjustable pre-bias and delay, dead-time selection and fast switching frequency selection. It also includes integrated charge pump and temperature protection features.

The IR2135 is also optimized for low EMI and power losses, thus making it suitable for high power applications. It is also well suited for motor control and offers full protection components and optional low-side MOSFET/IGBT options. Its adjustable current handling capabilities and switching frequency make it ideal for medium voltage and large area motor control applications.

The working principle of the IR2135 gate driver ICs is based on current sensing and voltage regulation technology. The driver utilizes a precision current sensing technique that monitors the power switching device. An adjustable current limit circuit is implemented to control the current during the turn-on of the device, and also reduces the turn-on losses due to voltage overshoot. By monitoring the temperature of the power switch, the IC can limit the current for extended periods in order to prevent the switch from overheating.

The IR2135 also has an adjustable switching frequency, enabling it to adjust the switching frequency of the MOSFET/IGBT to match the application load requirements. This improves the efficiency of the power switching device by reducing its switching losses.

In summary, the IR2135 gate driver ICs are well suited for motor control, switch-mode power supplies and high power amplifier applications. Its low-side MOSFET/IGBT features, adjustable switching frequency, adjustable current capability and various thermal protection features make it an ideal solution for high-power, high-temperature applications. Its integration of advanced protection components, adjustable output current limit and adjustable dead-time ensure protection of the power switch and reduce the turn-on losses due to voltage overshoot, thus improving the system efficiency.
