PMICs (Power Management Integrated Circuits) are integrated circuits that provide a variety of functions related to power management. This includes parts such as voltage regulators, motor drivers and controllers, and power switches. The DRV10987DPWPR is a part within this segment that is specifically designed for motor control in applications such as motorized cameras and motorized blinds. In this article, we will discuss the application field and the working principle of the DRV10987DPWPR.

The DRV10987DPWPR is a high-performance, three-phase motor driver with integrated MOSFETs that is designed for high-precision motor control in motorized cameras, motorized blinds, and other high-performance motor-control applications. This motor driver features a wide operating temperature range, a wide voltage range, a peak phase current of up to 1.2 Amps, and a continuous phase current of up to 0.6 Amps. Additionally, the DRV10987DPWPR offers programmable control modes, including current closed-loop control, voltage closed-loop control, and open-loop control. Furthermore, the part is designed to be compatible with common bus architectures such as I2C, SENT, and SPI.

The DRV10987DPWPR is intended to operate as a current driver in order to limit the current during motor start-up and operating conditions. During start-up conditions, the driver adjusts the duty cycle of the PWM signal based on the feedback from the current sense resistor. This enables the motor to start up at a safe current level. During operating conditions, the driver continues to limit the current. In the event that the current goes above a pre-set threshold, the driver will enter a protection state in order to limit the current. This provides enhanced protection for the motor and the driver.

The DRV10987DPWPR can also be configured to operate as a voltage driver, in which case the duty cycle of the PWM signal is adjusted based on the feedback from the output voltage sense resistor. In this mode, the driver will adjust the PWM duty cycle based on the feedback from the voltage sense resistor in order to maintain the output voltage within a certain range. This provides users with a high degree of control over the output voltage, enabling them to accurately control the output voltage of the motor.

The DRV10987DPWPR is also capable of providing open-loop control. In this mode, the driver continuously outputs a PWM signal at a specified frequency and duty cycle. This can be used to provide basic control of the motor without the need for feedback from the current or voltage sense resistors. This can be useful in applications that require basic motor control, such as motorized blinds.

In addition to the above control modes, the DRV10987DPWPR features a wide variety of integrated protection features, including overcurrent protection, short-circuit protection, thermal protection, and under-voltage lockout. These protection features can provide enhanced protection for the driver, the motor, and the system in which the driver is used. Additionally, the driver can be programmed to provide additional protection features, including a non-deterministic overcurrent limiting function, a peak current limiting function, and a dual-tolerance voltage regulation function.

As previously mentioned, the DRV10987DPWPR is designed for applications such as motorized cameras and motorized blinds. This motor driver provides users with high precision control of the motor, enabling them to accurately control the speed, position, and direction of the motor. Additionally, the driver features a wide variety of integrated protection features that provide enhanced protection for the driver, the motor, and the system.

In summary, the DRV10987DPWPR is a high-performance, three-phase motor driver that is designed for high-precision motor control in motorized cameras, motorized blinds, and other high-performance motor-control applications. The driver features a wide operating temperature range, a wide voltage range, a peak phase current of up to 1.2 Amps, and a continuous phase current of up to 0.6 Amps. Additionally, the DRV10987DPWPR offers programmable control modes, including current closed-loop control, voltage closed-loop control, and open-loop control. Additionally, the driver features a wide variety of integrated protection features that provide enhanced protection for the driver, the motor, and the system.
