Part Number: DRV8845 Tool/software: Hello Experts,
I am currently working on a project to drive three DC motors using the DRV8845 motor driver.
I am experiencing an issue where Motors 1 and 2 are functioning correctly, but Motor 3 is not working at…
Part Number: DRV8845 Tool/software: Hello Team,
My customer is evaluating DRV8845, and we are unsure if the unused driver related pins can be left floating or if there is a certain termination that needs to occur. Specifically, they will not be using…
Part Number: DRV8845 Other Parts Discussed in Thread: DRV8849
Tool/software:
The DRV8845 is fully pin-to-pin compatible and software compatible with the Allegro A3988, A5988, A5989, and Relmon MS3988 and MS3989. This means that you can directly replace…
Part Number: DRV8845 Tool/software: Can we operate each Full bridge individually and simultaneously? because I need to control four DC motors simultaneously with different PWM duty ratios

Please help to suggest a solution for BU24033GW replacement.
Thanks.
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…
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.
