PMIC - Gate Drivers: IR2301STRPBF Application Field and Working Principle

IR2301STRPBF is a high voltage, high current integrated gate driver from Infineon Technologies. It is designed for driving external VMOS, IGBT and other power semiconductor devices up to 600v. The integrated high voltage drive technology eliminates the need for bootstrap capacitors, making it ideally suited for both single and dual power supply applications.

The main feature of the IR2301STRPBF is its high efficiency performance. Its power conversion efficiency is up to 84%, which surpasses any competing solutions. Its 8 A peak output current enables it to drive a wide range of power semiconductor devices and it features a wide VCC range of 3.3V to 18V. Its integral bootstrap regulator ensures the circuit is protected against ground shifted voltage, short-circuit and undervoltage conditions.

Application Field

The IR2301STRPBF from Infineon is a high voltage, high current integrated gate driver that is ideal for use in a wide range of applications. These include, but are not limited to, motor control and drives, solar inverters, switch mode power supplies, and automotive powertrain. Its integrated bootstrap regulator ensures that the circuit is protected against most fault conditions.

Working Principle

The IR2301STRPBF features a high-voltage drive circuit that is capable of driving up to 600V. This high voltage drive is capable of driving all existing power semiconductor devices in both single and dual power supply applications. The IR2301STRPBF utilizes a high current output switch, a wide range of input voltage, and a unique bootstrap regulator design in order to ensure stable operation in all conditions.

The IR2301STRPBF features a driver flip-flop circuit, which is used to control the output switch of the driver. When the logic level of the control signal is high, the output switch is opened, resulting in an output low condition. When the logic level of the control signal is low, the output switch is closed, resulting in an output high condition. The IR2301STRPBF also features an integrated bootstrap regulator, which provides a stable supply voltage for the high voltage drive.

The IR2301STRPBF also features an integrator circuit that is used to differentiate the input signal from the control signal. This enables the driver to discriminate between positive and negative bits on the input signal and respond accordingly. This prevents false triggering of the output switch, resulting in reliable and stable operation.

Conclusion

The IR2301STRPBF from Infineon is an excellent choice for driving power semiconductor devices up to 600V in both single and dual power supply applications. Its integrator circuit ensures reliable and stable operation, while the integrated bootstrap regulator provides protection against ground shifted voltage, short-circuit and undervoltage conditions. It is ideal for use in motor control and drives, solar inverters, switch mode power supplies, and automotive powertrain applications.
