Part Number: DRV8838
The customer is using DRV8838 to drive a brushed motor.
But the motor current will decrease to negative value. And the speed of motor is very high.
Could you please why the current is negative?
Part Number: DRV8838 There is a game controller project in which DRV8838 will be used. The customer want to know: Is there anything to pay attention to when designing the control loop? and the FW control? Thanks

Dear Team,
There is a good news that we DIN DRV8838 in customer's new project.
Could you help to review the schematic?
Many Thanks

Hello: I want to use CC2652 generate PWM to control "DRV8838 H-Bridge Driver" and I noticed document about layout don't have protection circuit.
My question, if i want to do it right, do I need add some Protect for CC2652…

Hello,
I want to use PID to make sure the speed of the motors can maintain at the same value, but I don't know how to get the speed of the DRV8838 and…
Part Number: DRV8838 Hello,
I am in dire need of help!
I am trying to use DRV8838 motor drive to generate the following biphasic current pulse. Arduino pwm can provide EN and PH input to the DRV8838.
Note that is a "CURRENT pulse" and not a voltage pulse…
