DRV8210: PWM control input problem

Annie Liu

Part Number: DRV8210

Hi Team,

According to the above table, can it be understood that IN1 inputs PWM, IN2 inputs high or low level, and the load current can be changed by changing the PWM duty cycle through IN1?

Regards,

Annie

    Hi Annie,

    It looks like the table above if from the DRV8210EVM User's Guide. 

    The DRV8210 has three different control modes, PWM, PH/EN, and independent half-bridge. Table 4-2 shows how to drive a load with PWM control (MODE = Logic Low) on the DRV8210EVM. 

    Yes, by sending PWM (changing potentiometer position) signals to IN1 and IN2 held high (potentiometer completely clockwise) the motor speed will change in the reverse direction via IN1. Then by turning IN2 low (potentiometer completely counter-clockwise), the motor speed will change in the forward direction via IN1. 

    Best,

    David
