W83391TG TR Application Field and Working Principle

The W83391TG TR is a type of Power Management Integrated Circuit (PMIC) developed by Winbond Electronics Corporation and belongs to the motor drivers, controllers, and drivers category of PMICs. The W83391TG TR is a micro AC (MA) motor driver that can be used as a micro-remoter, electric fan, and micro-brushless electric motor driver. It incorporates a built-in power-on reset (POR), auto-buried start-up, auto-overload prevention, abnormal overvoltage protection, and phase loss protection.

The W83391TG TR can be utilized as a pre-driver for permanent magnet synchronous motors (PMSMs) and 3-phase brushless DC (BLDC) motors. It features high current ratings, wide Voltage range with adjustable peak current, low RDS(on), undervoltage lockout (UVLO), advanced current sensing and current limit protection. It includes PWM dimming, temperature compensation, and auto-adjust current control functions.

Working Principle

The W83391TG TR works by generating six independent gates for driving brushless exible motors. The driver utilizes PWM dimming to control the motor current. It uses three sets of differential two-way (UVW) outputs to control the motor current, thus providing a stable and efficient power conversion. It employs a voltage sensing control scheme that can be used to adjust the current values in the PWM limit lamp. It also utilizes a temperature monitoring device that can detect when the motor current is too high. When this is detected, the driver will automatically switch off the current.

In addition, the W83391TG TR has a built-in overcurrent protection function, allowing it to quickly shut off the current if the current exceeds the set value. This helps to protect the motor from being damaged due to excessive current. The W83391TG TR also includes a built-in POR, auto-buried start-up, auto-overload prevention, abnormal overvoltage protection, and phase loss protection, providing a robust package optimized for motor control.

Applications

The W83391TG TR is a multifunctional device and offers a wide range of applications. It can be used for brushless permanent magnet synchronous and three-phase brushless DC motor control. Its high current ratings and wide voltage range make it ideal for use in automotive, industrial, and consumer applications. It is well suited for use in micro AC motor drivers, electric fans, air conditioner blowers, and other similar applications.

The W83391TG TR is also highly reliable and is suitable for extreme climates, making it a sound choice for high-end applications such as electric vehicles and medical equipment. Its flexibility and versatility make it a valuable device in many applications.

Conclusion

The W83391TG TR is a type of PMIC that belongs to the motor drivers, controllers, and drivers category. It is a high-performance micro AC motor driver that can be used as a pre-driver for PMSMs and 3-phase BLDC motors. It features a range of features such as PWM dimming, current sensing and limit protection, temperature monitoring, and phase loss protection. It is an ideal choice for high-end applications and can be used in a variety of industries, from automotive to medical.
