PMIC - Motor Drivers, Controllers

DRV10963JUDSNRan intelligent power module that integrates， a dual H - bridge，a Hall - effect sensor and a pulse - width modulation (PWM) generator. The device is designed to drive low voltage brushed DC or brushless DC (BLDC) motors with Hall - effect sensors for feedback and has programs for protection for both the motor and the module, making it compliant with Safety Measurement Category 2 (SIL 2) guidelines.

Application field

The DRV10963JUDSNR is a motor driver mainly applied for Automotive, Industrial and consumer applications. With the device’s wide operating voltage range, it can be used as a replacement for lead - acid battery - operated devices and is ideal for applications such as BLDC fan controllers, automotive servo motors and industrial valve control. This device is specially designed to drive low voltage motors with Hall - effect sensors and integrated protection of both the motor and the module, making it compliant with Safety Measurement Category 2 (SIL 2) guidelines.

Working Principle

The like most motor drivers, the DRV10963JUDSNR uses an H - bridge architecture to provide a reversible, bidirectional current to the motor. This requires four switches (or transistors). When the upper left switch is closed and the lower right switch is open, the applied voltage will turn the motor in one direction. Inversely, the lower left switch is closed and the upper right switch is open, the applied voltage will turn the motor in the reverse direction. In order to generate feedback signals for the motor, the DRV10963JUDSNR uses a Hall Effect sensor. The Hall Effect sensor is integrated and detects the magnetic field around the motor, thus generating feedback signals. It is common to use the PWM inputpins to control the device. As the PWM signals are received, the H - bridge will regulate them accordingly. The DRV10963JUDSNR also has integrated current sense pins that can be used to measure the motor current. The device is capable of measuring and monitoring the current flowing through the motor to protect it from damage due to overloads. The device also has integrated overvoltage protection and thermal shutdown to protect the motor and the device itself. It also has a fault flag pin to indicate that a fault has occurred.

Conclusion

The DRV10963JUDSNR is a robust motor driver module that is capable of driving low voltage brushed DC or brushless DC (BLDC) motors with Hall - effect sensors for feedback. The device is designed to have integrated protection of both the motor and the module, making it compliant with Safety Measurement Category 2 (SIL 2) guidelines. It is well suited for applications such as BLDC fan controllers, automotive servo motors and industrial valve control.
