PMIC (Power Management Integrated Circuits) and gate drivers are two key types of power management components used in designing and regulating efficient systems. PMICs and gate drivers work together to regulate the power system at the component level. The combination of PMIC and gate drivers can boost system performance and reduce power losses. This article will discuss the application field and working principle of RT9624BZQW, a power management integrated circuit (PMIC) and gate driver.

Application Field of RT9624BZQW

The RT9624BZQW is a dual-channel gate driver with advanced protection features. It is commonly used in applications such as AC induction motor control, brushless DC motor control, automotive ECU, and switch-mode power supply (SMPS). The RT9624BZQW features MOSFET driver protection features such as over-temperature protection and over-voltage protection. It also provides adjustable bump protection for the MOSFET driver, which helps ensure smooth operation even during high-current surges.

The RT9624BZQW also features built-in under-voltage protection (UVP) and over-voltage protection (OVP). These features help protect the gate drive circuit from over-voltage and under-voltage events. The built-in OVP protection feature is also able to prevent damage caused by switching a power MOSFET under an over-voltage condition. In addition, the RT9624BZQW includes a “thermal shutdown mode” that can be used to protect the device from any thermal damage.

The RT9624BZQW also has a built-in high-current sense resistor. This helps to detect input current levels and prevent any over-current events from occurring. Additionally, the RT9624BZQW is compliant with safety standards such as IEC60601-1, SELV, and EN60335-1. It also includes many common-mode EMC filter options, making it a reliable component for addressing EMI/EMC concerns.

Working Principle of RT9624BZQW

The RT9624BZQW is a dual-channel gate driver featuring advanced MOSFET protection and a high-current sense resistor. It works by monitoring the input power and controlling the power MOSFETS gate voltage. When an over-temperature or over-voltage event is detected, the RT9624BZQW switches to a “thermal shutdown” mode and MOSFET drives are disabled until the source voltage has dropped below the OVP threshold.

The RT9624BZQW also features a built-in bump protection circuit. This circuit helps prevent the power MOSFET from over-heating and helps ensure smooth automatic shutdown of the MOSFET. The boost circuit also helps conserve power and reduce power losses during the operation of the device.

In addition, the RT9624BZQW is compliant with safety standards and includes common-mode EMC filter options. This helps reduce electrical noise and interference in the circuit. The device also includes an integrated high-current sense resistor, which helps to monitor input current levels and prevent any over-current events from occurring.

Conclusion

In conclusion, the RT9624BZQW is a dual-channel gate driver with advanced protection features and integrated EMC filter options. It is commonly used in applications such as AC induction motor control, brushless DC motor control, automotive ECU, and switch-mode power supply (SMPS). Its additional features, such as bump protection, high-current sense resistor, and safety standard compliance, make it a reliable component for designing and regulating power systems.
