Automotive power management ICs (PMICs) provide efficient and reliable power regulation, power conversion, thermal management, and intelligent system control for onboard automotive electronics. The ATA6823-PHQW is a high-performance automotive, three-phase dc-motor driver solution with integrated smart features suitable for low-power automotive applications and a fully-integrated full-bridge driver with a maximum output current of 3A. It is available in a quad flat-pack (QFP) or TQFP package.

ATA6823-PHQW is a integrated power management IC suitable for automotive motor drives, controllers, and systems. It has two separate motor drives and an onboard microcontroller for safety-critical system control applications. The ATA6823-PHQW can control two separate DC motors from a single polarity power supply. It has an integrated gate driver with Fault Flag Interrupt (FFI), over-temperature protection, and all-tracking ESD protection. The FFI provides a simple, low-power method for monitoring and controlling the motor’s speed and direction.

The ATA6823-PHQW is designed for low-power automotive applications and has a wide input voltage range of 8.5V to 28.8V. The device supports a wide range of step/direction input signals, PWM control and can be programmed to perform a variety of control functions. It is highly efficient, with an integrated low RDS(on) synchronous gate driver and an on-chip start-up current limiting circuit. The on-chip thermal shutdown feature prevents the device from over-temperature conditions and the FFI feature provides a low-power, reliable safety critical monitoring and control of the motor speed and direction.

The ATA6823-PHQW is designed for high-performance automotive applications. It provides fault information and advanced control functions such as zero-speed detection, back EMF detection, current overload protection, and motor stall detection. The device also has an adjustable motor stall protection threshold, adjustable motor drive current and motor speed-control settings. The ATA6823-PHQW is designed for a wide range of automotive applications such as windscreen wipers, engine cooling fans, and centrifugal pumps.

The ATA6823-PHQW supports the full range of motor operation modes and provides accurate control of motor speed, direction and acceleration. Motor drive current can be regulated over a wide range and the ATA6823-PHQW provides flexible software and hardware settings to optimize performance. The device is highly configurable with a wide range of settings for motor speed, current, acceleration and deceleration.

The ATA6823-PHQW operates in both linear and pulse-width modulation (PWM) modes, providing precise current control and precise motor speed control. The PWM mode is ideal for high-performance automotive applications that require precise, highly efficient operation. The linear mode is ideal for applications that require precise motor speed control and low power consumption.

The ATA6823-PHQW also has advanced diagnostic and safety features such as thermal shutdown, under-voltage lockout, over-voltage protection and current overload protection. The device also supports Enhanced Diagnostic and Safety features, including back-EMF detection and triple redundant start / stop logic. The device also supports external single-wire communication with a host controller.

The ATA6823-PHQW is an ideal solution for automotive motor drives, controllers and systems. It has high performance, low power consumption, integrated safety-critical system control, and a wide range of motor control features. It is a robust, reliable and highly integrated solution for low-power automotive applications.
