PMIC can be better defined as power management integrated circuits. These replace the cumbersome assembly of individual active and passive components that make up the traditional DC-DC, voltage regulator and other control circuits with an integrated circuit. They generally simplify the design process, reduce costs, and increase safety and reliability while still providing robust power management solutions.
The ATA6823C-PHQW-19 PMIC is a robust power management integrated circuit designed for motor drive and control applications. This PMIC is designed to provide a stable supply voltage to the motor driver and control circuitry, as well as to enable programmed current limiting for the motor drive. In addition, this device also has several integrated features such as a voltage reference and PWM mute, enabling fast switching and noise suppression.

• High efficiency operation across the entire operating range
• Integrated voltage reference and PWM mute to enable fast switching and noise suppression
• Programmable current limiting for motor drive to ensure safe operation
• Lower standby current compared to other PMICs
• On-board temperature sensing for enhanced safety
• Pin compatible with other ATA PMICs for easy design upgrades

• Automotive electronics
• Robotics control
• Industrial automation
• Home appliance motor control
• Consumer electronics

The ATA6823C-PHQW-19 PMIC is an integrated power management chip that works in two basic stages. First, it uses a high-efficiency DC-DC step up (BOOST) converter to provide an increased supply voltage to the motor driver circuitry. This can be done at any voltage between 6V and 36V. Secondly, the device monitors the current through the motor driver and can be programmed to limit any excessive current draw. This protects the motor from overloading, as well as protecting the rest of the circuitry from any overload conditions.

The ATA6823C-PHQW-19 also has a number of integrated features that help to improve performance and safety. It has an integrated voltage reference to provide an accurate reference voltage for the PWM control, as well as an integrated PWM mute which allows for fast switching and noise suppression. Additionally, it also has on-board temperature sensing for enhanced safety. This helps to avoid any dangerous thermal runaway conditions that could occur within the motor drive system.

Overall, the ATA6823C-PHQW-19 is an extremely versatile and powerful PMIC providing numerous features and benefits to motor drive and control applications. It provides a stable supply voltage to the motor drive and control circuitry, while also providing safety features such as current limiting and temperature sensing. This enables designers to confidently and safely develop motor drive and control circuitry with the assurance that the device will perform reliably and with minimal risk of harm.
