Power Module integrated circuits (PMICs) are integrated circuit devices used in managing power and providing a direct current (DC) power supply. PMICs mainly cater to the mobile and embedded applications, which are primarily used in portable electronics and an increasingly wide range of other industries. They are available in a variety ofephysical formats, such as discrete components, integrated modules and integrated circuits. The PMIC product family include motor drivers, controllers and motors.

One of the most common uses of PMICs is motor control. Motor drivers, controllers and motors are used to control the operation of motor-driven applications. The DRV8701PRGER is a motor controller IC from TI (Texas Instruments) that integrates advanced control techniques with robust drivers and power MOSFETs to achieve optimal performance. This device is suitable for use in motor pulse width modulation (PWM) control applications.

The DRV8701PRGER is suitable for managing the operation of a single motor or two motors in brushless DC (BLDC) applications. It contains a 3-phase bridge driver with high side current sensing and current regulation via pulse density modulation (PDM) control to improve system efficiency. The integrated gate driver minimizes the external components required and provides a low-noise output, while the current sensing regulator limits the output current to the value set by the user. Additionally, the DRV8701PRGER offers both inductive and resistive load protection.

To control the motor, the DRV8701PRGER uses a PWM technique that generates a gate drive waveform and requires a periodic clock signal for synchronization. The device features a PWM control block that generates the control waveforms for the motor. This block uses a timer to generate the PWM frequency, and a set of comparators that convert the analog input signals into digital signals. The PWM timer is also used to keep track of the motor phase angle and the current. The device also features an auto-configuration block which automatically configures the device for the current motor. This feature simplifies the design of the system and reduces the amount of manually configured parameters.

The DRV8701PRGER also includes current and voltage feedback circuitry, which can be used to further protect the motor from over current and over voltage. In addition, the device offers protection against temperature, under voltage, and over voltage. These features ensure reliable operation of the motor control system. The device can also be used in applications that require Hall Effect sensors or encoders.

The DRV8701PRGER is a highly efficient and versatile motor controller IC designed for a wide range of applications, such as electric lawnmowers, boats, industrial automation, and robotic arms. This device offers a compact design, with a small form factor and excellent power saving capabilities. It is widely used in various industrial and consumer applications.
