The DRV8801RTYT is an integrated motor driver module designed for PMIC - Motor Drivers, Controllers. It integrates two identical high-performance, wide voltage range, and high current H-bridge drivers, together with a voltage boost regulator and a microcontroller (MCU). This device is designed to driver both brushless and brushed DC motors, as well as stepper motors. The DRV8801RTYT provides a reliable and efficient solution for driving motors in robotics and industrial automation applications.

The DRV8801RTYT can operate over a wide range of input voltages from 3.3 V to 27 V, which makes it suitable for a variety of applications. It also features adjustable switching frequency, current sense, and motor-braking capabilities. The device also includes an on-board MCU to provide features such as pulse-width modulation (PWM) control and motion profile controls, which allows for greater flexibility when controlling motors. The MCU can also be programmed to handle sophisticated motion control algorithms, such as position and speed control.

At the heart of the DRV8801RTYT is the voltage boost regulator, which is used to power the H-bridge drivers and the MCU. The voltage boost regulator is designed to maximize efficiency while maintaining a low quiescent current. The device can deliver up to 3 A of continuous output current and a maximum peak current of 5 A. It also has two logic input pins, which can be used to set the direction of the motor and enable/disable its operation.

The two H-bridge drivers are designed to drive both brushed and brushless DC motors and can support a wide range of motor voltages. The drivers are designed to be tolerant to high-frequency voltage fluctuations and can withstand up to 7.5 V of reverse voltage without damage. The H-bridge drivers also support a peak current of 5 A, and the device can support a maximum motor speed of up to 22,000 rpm.

The DRV8801RTYT includes on-chip protection features to ensure reliable operation, such as over-temperature protection, driver over-rather protection, and thermal shutdown. It also includes a soft start feature to reduce inrush current during startup, which can help extend motor lifetime. The device also includes a range of diagnostic features to allow for fault detection and motor control optimization.

In summary, the DRV8801RTYT is an integrated motor driver module designed for PMIC - Motor Drivers, Controllers. It can operate over a wide range of input voltages and offers various features to enable efficient and reliable motor control. The device integrates two high-performance H-bridge drivers, a voltage boost regulator, and an MCU to provide sophisticated control algorithms and protection features. This makes the DRV8801RTYT an ideal solution for robotics and industrial automation applications.
