RT9625BZQW Application Field and Working Principle

RT9625BZQW belongs to the PMIC (Power Management Integrated Circuit) family and can be classified as aGate Drivers. PMICs are integrated circuits used to manage power andrarely contain components to directly supply power, relying instead on connections to external power sources. They vconverter DC (direct current) sources to AC (alternating current) or they may function as regulators, preventing power sources from exceeding their maximum current and voltage ratings.

A Gate Drivers is a type of power supply designed to drive logic circuits, switching circuits and other power components. The output from a gate driver is typically a high-frequency, high-voltage pulse-width modulated pulse train.Pulse width modulated pulses are typically used to control the switching of electronic transistors such as MOSFETs, IGBTs and thyristors.Thyristors (or SCRs for Silicon Control Rectifiers) are electronic switches that are used for regulating and controlling currents in power system equipment . The RT9625BZQW Gate Driver is designed specifically for use in controlling and regulating thyristors.

The RT9625BZQW is a high-voltage gate driver with a reverse current protection and current limitation. The device can switch up to a maximum of 5A in the load current mode and 5.2A in the over current limitation mode. It features a wide input voltage range of 2.6V to 20V and a switched output voltage range of 9V to 50V. The device is also capable of driving high power thyristors with a switching frequency of up to 350kHz. The device also has a soft-start feature that helps to reduce inrush current and effectively reduce power dissipation. It also has a thermal protection featurewhich prevents heat damage to the thyristor or other circuits.

The RT9625BZQW is typically used for various commercial and industrial applications, including power semiconductor controllers, motor controllers, switch mode power supplies, AC/DC converters, and home automation system. The device is designed specifically for industrial applicationswhere high voltage and high power MOSFETs and IGBTs are driving high power loads.

The RT9625BZQW is a highly versatile, configurable and easy-to-use module. It can be used as a benchmark for evaluation and design-in of modern, high-performance gate drivers. Its features, compact size and relative simplicity make it an ideal solution for high-power applications across all industrial sectors.

The RT9625BZQW has a high voltage and high power,reverse current protection and current limitation, thermal protection and soft-start features. It has a wide input voltage range of 2.6V to 20V, an output voltage range of 9V to50V and a peak switching current rating of 5A. The device is easy to configure and provides a reliable, stable and consistent performance.

The working principle of RT9625BZQW isas follows. The voltage applied at the input is detected and used to control the switching of the thyristor or other types of power transistors. The input voltage is converted to a pulse width modulated (PWM) signal, which is then used to control the gate of the MOSFET and thyristor in the load, controlling the current in the load and regulating the voltage across the load. When the output voltage rises above a certain preset threshold, the device will shut off the thyristor or other power transistor, thus preventing the voltage from increasing any further. The module can also be used to control the speed of the motor or other system. It can also be used to control the timing of the switching of the system by adjusting the pulse width or pulse frequency of the PWM signal.

In summary, the RT9625BZQW Gate Driver is designed specifically for usein controlling and regulating high power thyristors across various industrial applications. With its wide range of input voltages, output voltages, peak switching current andthermal protection features, the RT9625BZQW is a highly versatile, reliable and easy-to-use module thatcan be used as a reference for evaluation and design-in of modern, high-performance gate drivers.
