Application Field

The ATA6837-PXQW19 is suitable for a wide range of motor-driven applications, including industrial motor drivers, drive controllers for home appliances, automotive engine controllers, and battery control systems. It is also used in power converters and dc-dc converters for automotive and commercial applications.

The motor driver PMIC is especially suitable for applications that require high-speed operation and fast response. These include gate drivers, brushless DC (BLDC) motors, AC synchronous motors, and miniature Stepper Motors.

The advanced features of the ATA6837-PXQW19 make it an ideal and reliable motor controller for all sorts of motor-driven applications, including those requiring precision in position and speed control.

Working Principle

The ATA6837-PXQW19 is designed to improve the efficiency, reliability and accuracy in motor-driven applications. It is a 3-phase, high-power component that is based on a PWM control scheme. The pulse-width modulation (PWM) control scheme allows for low-noise and efficient operation.

The core feature of the controller is its fault-tolerant and power-up protection circuit. It has the ability to detect and respond to various fault conditions quickly and accurately, including low-voltage, over-voltage, short-circuit, and over-temperature. The controller will automatically shut down in the event of an emergency.

The ATA6837-PXQW19 includes several protection and control features such as an on-chip temperature sensor, current and voltage regulation, and programmable parameters. It also includes an integrated power failure protection circuit that monitors and responds to any power interruptions.

The controller also supports three modes of operation: closed-loop, open-loop, and output-feedback. In the closed-loop mode, the PMIC continuously adjusts the output power according to a given setpoint and the feedback signal. In the open-loop mode, the PMIC adjusts the output power depending on the input signal, while in the output-feedback mode, the PMIC responds to the output currents and powers.

The ATA6837-PXQW19 PMIC has an integrated motor control unit (MCU) that uses an on-chip 8-bit CPU to execute software instructions. This MCU allows for easy customizability and integration of features. The MCU can be used to control the power, adjust the speed, and set up diagnostic functions.

The ATA6837-PXQW19 is designed to provide high accuracy in terms of current and voltage regulation. It offers adjustable voltage, current and frequency ranges for optimal performance in various applications. The output voltage and current can be dynamically adjusted for smooth and fast transitions.

Overall, the ATA6837-PXQW19 PMIC provides a reliable and efficient solution for applications such as industrial motor drivers, automotive controllers, home appliances, battery control systems, and dc-dc converters.
