The MPC17511AEP is a Motor Driver that is part of the Power Management Integrated Circuit (PMIC) family. It is designed to control and regulate power and current levels for motors, actuation systems and other related applications. The device is composed of the core PWM unit, the Dual Analog-to-Digital Converter (ADC) and the Serial Peripheral Interface (SPI)

The core PWM unit consists of a high-side driver, a low-side driver and a logic block that handles all the control logic. The high and low-side drivers both handle the voltage feedback for the motor and the logic block monitors the position and velocity set-points. The Dual ADC converts input voltage and current signals into digital signals for the control logic to work with.

The SPI port is used for communication with the external microcontroller. It provides the user with programmable control parameters such as field suppression, soft start, torque ripple, field weakening and error tolerance. The MCU also handles the protection system for the motor, monitors the motor temperature and other conditions, and implements various diagnostic and control algorithms.

The MPC17511AEP also features a low-current start-up and a high switching frequency of up to 250 kHz, which allows for faster control of the motor. It also has an integrated over-temperature protection circuit and can handle up to 28V supply voltages. The MPC17511AEP arrives in a 6x6mm QFN package and is suitable for working in harsh environments and at temperatures ranging from -40°C to 125°C.

In addition, the chip can handle up to 0.15A peak current, which allows for high performance applications such as brushless DC (BLDC) motor drive and stepper motor control. It is also suitable for industrial applications this require precision current control and low EMI. The chip is also compact, cost-effective and provides an easy-to-use control interface for the user.

In short, the MPC17511AEP is an effective Motor Driver for controlling motors and various actuation systems. It is designed for precision process control and EMI reduction and its wide operating voltage and temperature range make it suitable for industrial applications. With powerful PWM control capability and an integrated over-temperature protection circuit, it is a great option for a variety of motor control applications.
