DRV8212: Is there any motor driver which has a function of load monitoring?

Dear TI experts,

My customer tests DRV8212, but they have a problem because they cannot see the current load of motor driver.

Is there any motor driver which has a function of load monitoring when it is working?

Supply voltage to the motor is 3V~4V, operating current of motor is about 20mA~50mA.

Bigger gain is preferred. (Big voltage change is detected even in small current changes.)

Best regards,

Hi Chase,

In order to monitor the load of while the motor is running, you would need a motor driver with current sensing. Current sensing could also be implemented externally to the motor driver with an op-amp and comparator that is fed back to the MCU; however, TI offers multiple motor drivers with integrated current sensing, or even with current sense amplifiers.

Please see the following links to suggested motor drivers:
