Part Number: DRV8251AEVM Other Parts Discussed in Thread: MSP430F2618 , MSP430FR5969 , , MSP430FR2100 , MSP430F2617 I am trying to program the DRV eval board using a MSP430FR5969 LaunchPad and CCS with the downloaded firmware for the DRV eval board (slvc831…
Part Number: DRV8251AEVM Tool/software: As dispicted in DRV8251AEVM user guide, Pot1 controls the PWM signal that goes into IN1, by turning it clockwise you increase the duty cycle from 0% to 100%. But when I use this evaluation board to drive a motor…
Part Number: DRV8251AEVM Other Parts Discussed in Thread: DRV8251A Can you provide the following information for DRV8251AEVM
1) Schematic
2) Calculation for VSense. It is not clear what Rsense is on the eval board,
3) Itrip value for the board as…
Part Number: DRV8251AEVM Other Parts Discussed in Thread: DRV8251A Hi,
We are testing the DRV8251A on a brushed DC motor (24V 4A). The development board has two potentiometer to set the motor speed in both directions.
Our problem is; the motor is…
Part Number: DRV8251AEVM Dear Team,
My customer is evaluating the DRV8251AEVM, and wants to know the thickness of the copper foil of the DRV8251AEVM. I checked the DRV8251_DRV8251AEVM Hardware Files , but I did not understand that.
Could you let me…
Part Number: DRV8231A Other Parts Discussed in Thread: DRV8251AEVM Hi Team,
Our customer tested DRV8231A when no motor was connect to the OUT1 and OUT2.
They input 30% PMW to PIN1 or PIN2 and found some chips' current IPPOPI feedback was not zero…
Hello Saad,
It sounds like you have the DRV8251EVM because of its 150m Ω sense resistor (R7), the DRV8251AEVM has a 0Ω sense resistor (R7).
Current regulation on the DRV8251 should have a latched disabled response for overcurrent protection, while…
Hi Tomek,
We don't have a specific FMEA for this device. However, my suggestion would be to order the DRV8215AEVM and test for yourself.

Hi Jagdish,
From a design perspective the schematic seems ok.
As long as the DRV8251A is operated within recommended specifications, it will be fine.
As I mentioned earlier I would suggest simulating or testing the layout first with the DRV8251AEVM…
Hey Todd,
Apologies busy day, haven't had time to dig into the DRV104 datasheet for this yet.
So for a 24V / 2A peak / 1A continuous motor driver, I would recommend DRV8231A . It's a 35-V, 3.7-A H-bridge motor driver with integrated current regulation…
