Part Number: DRV8876

Hi,

I am using DRV8876PWPR , which how to configure pin 1 (EN/IN1) and pin 2 (PH/IN2)  in microcontroller side?  Since, having doubt in configuring them as PWM (Timer) or a GPIO. 

Kindly, clarify the above query

Regards, 

Anjanaa

    Hi Anjanaa,

    There are several options available:

    1) Use PH/EN or PWM mode without PWM'ing the inputs. For this, set the inputs as GPIO.

    2) PWM the inputs in PH/EN mode. For this, configure the EN input as PWM timer and PH as GPIO.

    3) PWM the inputs in PWM mode. For this, configure IN1 or IN2 as PWM timer and the other as GPIO.

    Please consider a DRV8876EVM to evaluate the various modes.
