Part Number: DRV8844 Hi We are trying to apply input PWM to DRV8844, we want to know what is the maximum PWM frequency that can be handled by DRV8844.?
Part Number: DRV8844 I have an issue with DRV8844 charge pump circuit - our product fails radiated emissions EMI testing presumabily because the charge pump of the driver creates a train of harmonics spaced approx. 302 kHz apart. Disabling the driver…
Part Number: DRV8844 Hi TI team,
I am developing control logic for DRV8844 full H-bridge drived solenoid following the below logic from the datasheet:
The existing algorithm logic is based on Forward PWM with fast decay.
The current flows during…
Part Number: DRV8844 Hello,
In our design, VM is not supplied at the power-up of the board but the logical side is.
It seems that there is a repowering of VM through either NRESET or the EN/IN pins in that condition as we observe about 2.7V on VM…
Part Number: DRV8844 Tool/software: What could be the reason for Fault being always asserted? Schematic below; I'm trying to simply get the part working, not drive anything yet. V3P3OUT does output 3.3V.
Part Number: DRV8844 Tool/software: Dear all,
I am doing FMECA (Failure mode, effects, and criticality analysis) on an electronic board that includes the DRV8844.
I am having difficulty deriving possible behaviors of the component in 4 specific cases…
Part Number: DRV8844 Tool/software: Could you please help check if there is any problem with the schematic design of DRV8844, thks
The second page of the document is the DRV8844 design

Part Number: DRV8844 Tool/software: Dear,
The Marking format of Figure 1 is different from that of Figure 2, they are the same part number, and I can't find the relevant PCN, I would like to know if this is a normal?

Part Number: DRV8844 Tool/software: Hello,
We are currently using the DRV8844 in order to drive a DC motor with slow decay. We are connecting the two outputs of the driver in parallel in order to increase the maximum current that can be drawn from…
Part Number: DRV8844 Tool/software: Hi
Regarding DRV8844..
The idea is to trigger an automatic reset in the event of an error (nFault = low) with a small circuit, unfortunately the following information is missing in the data sheet: -) minimum reset…
