Part Number: DRV8845 Hi,
We have used DRV8845RHHR in our project to drive stepper motor having following specifications.
1) No of phase - 2
2) Phase voltage - 6.6V
3) Phase current - 1A
4 ) Phase resistance - 6.6ohms
5) Size : NEMA 17
The applied voltage…
Part Number: DRV8845 Other Parts Discussed in Thread: DRV8912-Q1 , DRV8849 Hi Team,
Please help to suggest a solution for BU24033GW replacement.
Thanks.
Part Number: DRV8845 Hi,
For BLDC, we often choose a higher voltage level IC in a lower DC bus system because the DC bus will rise during brake.
But I'm not sure if it's the same for stepper motor.
And how much margin voltage should we have.
Part Number: DRV8845 Hello team,
My customer is considering to use DRV8845 with 4 Brushed DC motors. However, they want to use Brake (slow decay mode).
From the datasheet Table 8-5, there is no Brake statement on the truth table.
Can DRV8845 use Brake…
Part Number: DRV8845 Hello,
The DRV8845 datasheet states that there are 3 modes for controlling a DC motor, forward, reverse and coast but it also has dynamic decay mode for current control.
Can the dynamic decay mode be used when the DRV8845 is driving…
Hi Henry,
The DRV201A would be a good solution for lens control of IP camera. We typically see both brushed and stepper motor drivers often used as well for IP camera design.

Part Number: DRV8434S Other Parts Discussed in Thread: DRV8845 Tool/software: Hi,
I would like to know if the DRV8434S drivers can also be connected to a brushed DC motor.
Thanks.
Hello,
I suspect that in practice this will not affect anything. Both devices likely have some room for error built into that number. I would verify this by measuring the output voltage on the MCU once a board is built just to make sure it is closer to…
Het Kitadasan,
I will confirm with design team on what it should be. However, I am 90% certain it should be PGND, since the DRV8845 which shares the same die/package has pin 30 listed as PGND.
Best,
Jacob
