HELLO,

HOW TO USE IN1 AND IN2 PINS IN DRV8842 

IF I HAVE TO GIVE A GENERATED PWM  FROM CONTROLLER AND CONTROL THE LOAD CURRENT USING I0-I4 SETTING 

(CAN I GIVE DIRECTLY SAME PWM TO IN1 AND IN2)

THANKYOU.

    Hello Vinay,

    IN1 and IN2 are input pins which control the state of OUT1 and OUT2 outputs. The detailed logic is shown below, also specified in the datasheet.

    If you are not interested in current regulation then you can get by without using I0-I4 pins. Thank you.

    hey ,

    thank you for the reply 

    ya i have been through that part in data sheet as i am not into embeded field,

    moto is that i have to drive solenoid and control the load current linearly during actuation, so i have a dither added pwm from controller my question is can i give this pwm only to IN1 and expect the output at OUT1 (can i drive the solenoid) or should i have to generate two pwm signals for IN1 & IN2.

    thank you.
