Part Number: DRV8837 Other Parts Discussed in Thread: DRV8838 , DRV8210 Dear TI Technical Support Team,
I am designing a board that will be used to control direction and speed of 2xDC hobby motors (3-9V, 110RPM). Two of them can draw at most 250-300mA…
Part Number: DRV8837 Other Parts Discussed in Thread: DRV8838 , , DRV8873-Q1 , Hi,
There are two questions regarding DRV8837/DRV8838 motor driver IC.
1. I did a simple test in LTspice using DRV8837. I set In1 to 0V and IN2 to 3.3V. I expect to see…
Part Number: DRV8837 Other Parts Discussed in Thread: DRV8212P We use pairs of DRV8837 to drive 2-phase piezoelectric motors. They run near resonance, so capacitive and not a simple load. The peak currents can exceed plus and minus 2 amps (2 divisions…
Part Number: DRV8837 Other Parts Discussed in Thread: DRV8212P Hello,
The datasheet for the DRV8837 does not list a dead time, is there a reason for this? The similar DRV8212P has a parameter regarding dead time.
Best regards, DDdoor
Part Number: DRV8837 Hello,
I am performing low-side current measurement for the motor fault detection. As shown in the attached image, in left side I was using transistor for motor bridge and 0.1 Ohm resistor for motor current failure detection.…

Hi !
I have been using the DRV8837 H-Bridge since past four years and faced no issues what-so-ever with its performance. It is used to drive a coil with a total…
Part Number: DRV8837 Hello all,
we have chosen to use DRV8837 as a low voltage DC motor driver in a full H-bridge configuration. It must allow us to control the power through PWM signal.
Unfortunately it is a bit problematic to use two PWM signals…
Part Number: DRV8837 Hi Team,
The customer would like to know whether the voltage range of the VM pin needs to match the input voltage range of the motor? How to determine the voltage of the VM pin?
Thanks,
Annie
Part Number: DRV8837 I've incorporated a DRV8837 into my motor application. VM is supplied by a boost regulator that maintains an output of 7V.
When I drive the motor and then abruptly brake, I see the expected negative flyback current coming from the…
