Power management integrated circuits (PMICs) are a type of electronic component used to manage the power of various electronic devices. One such PMIC, the IR2130, is a high-voltage and high-power gate driver for applications such as motor control, AC inverters, and switched-mode power supplies. This article will outline the application fields and working principle of the IR2130.

Application Domains and Usage

The IR2130 is suitable for a wide range of applications, such as power transmission and board-level protection, motor control, AC inverters and switching power supplies. In power transmission and board-level protection applications, the IR2130 is used to gate MOSFETs, relays, and TRIACs to enable/disable power circuits, helping to protect downstream components from unexpected damage due to short circuit, overcurrent, and overvoltage events. Similarly, the device can be found in motor control applications like brushless DC motors, where it is used to drive the MOSFETs that control the phases.

The IR2130 is suitable for AC inverter applications. It can provide symmetrical or asymmetrical drive, depending on the application requirements, for switching MOSFETs at over-voltage, over-current and no-load conditions, exhibiting a high degree of reliability in such applications. Additionally, switching power supplies are made more efficient with the usage of the IR2130, as it can rapidly switch the MOSFETs for higher frequency operation. As a result, switching losses are reduced, allowing for a more efficiently designed circuit.

High-voltage and High-power Gate Driver

The IR2130 is a high-voltage, high-power gate driver. It uses the bootstrap circuit with high-voltage and low-voltage supply. It consists of two output channels to drive the gate of upper and lower MOSFETs. This gate driver can provide up to 10A peak current and up to +/- 15V gate drive voltage, allowing it to drive large MOSFETs. The driver also includes a slew rate generator, allowing it to control the rise and fall times of the outputs for better switching times.

Internal Working Circuitry

The IR2130 contains internal circuitry which allows it to perform its gate driving function. It consists of an error amplifier, an under voltage lockout circuit, an oscillator, and a voltage reference. The input signals are first processed by the error amplifier, which can detect over-voltage and under-voltage conditions on the input. It then provides error correction signals through its output. The gate driver\'s power is then supplied by the under voltage lockout circuit, which regulates the supply voltage and prevents unexpected shutdown due to low voltage.

The oscillator is used to generate the switching signals for the MOSFETs. The voltage reference provides the reference voltage for the error amplifier and the under voltage lockout circuit. The output drivers are driven by these signals in order to drive the MOSFETs. The slew rate generator is also included, which controls the rise and fall times of the output signals.

Conclusion

The IR2130 is a high-voltage and high-power gate driver, suitable for a broad range of applications, such as power transmission and board-level protection, motor control, AC inverters and switching power supplies. It uses a bootstrap circuit with high-voltage and low-voltage supply, and is capable of providing up to 10A peak current and up to +/- 15V gate drive voltage. Additionally, it contains internal circuitry such as an error amplifier, an under voltage lockout circuit, an oscillator, and a voltage reference, which allow it to perform its gate driving function. Furthermore, it includes a slew rate generator which can control the rise and fall times of the output signals.
