Hi Deekshitha,
Thanks for the scope shots.
1. Based on the waveform the PWM from the MCU is having a spike as seen in the yellow trace. This is your firmware related issue. When the button was pressed the IO port is being written with a LOW and back to…
Part Number: DRV8243-Q1 Other Parts Discussed in Thread: DRV8705-Q1 , , DRV8245-Q1 , DRV8244-Q1 , DRV8703-Q1 , DRV8262 , DRV8262-Q1 Hi ,
We are planning to use DRV8705-q1 for driving a brushed Dc motor of 8A A(apx).
Need clarification on below points.

Part Number: DRV8243-Q1 Other Parts Discussed in Thread: DRV8245-Q1 Hello,
When DRV8243 is driven up to 7.9A it is working fine as intended. but When it is driven at 8A load , the nFAULT is becoming active after some time(sec).
Can you please let me known…
Part Number: DRV8243-Q1 I have interface the motor driver DRV8243PQDGQRQ1 with my MCU. When i probe my DSO with SPI lines (SCLK,SDO,SDI), motor runs. If i remove the probe, SPI communication fails.
But even i touch the SDO line with open probe, motor runs…
Part Number: LP-MSPM0L1306 Other Parts Discussed in Thread: MSPM0L1306 Hi all, I would like to program the MSPM0L1306 to communicate with the motor driver DRV8243S via SPI, so it drives the motor for 50ms. My question is, does a code example exist, where…
Part Number: DRV8243-Q1 Hello,
I have an issue where the nFault of the driver is constantly triggered, even after performing a reset pulse on the nSleep IO. Yellow - nSleep Purple - nFault My DRV is connected as following: I've used 2 other DRVs by TI, but…
Part Number: DRV8243-Q1 Hi,
I would like to know outputs state when driver is not powered. Indeed, datasheet indicates that driver outputs are in Hi-Z when for example SLEEP pin is active but I didn't find any information about outputs state when driver…
Part Number: DRV8243-Q1 Hello team,
Have a nice day.
Customer are testing TSD function of DRV8243-Q1, and they found the phenomenon:
First, the experiment was carried out in the incubator, and the TSD bit was reported when the device around 175C;
Then…
Part Number: DRV8243-Q1 Hi,
We are using DRV8243-Q1 for motor control, and using SPI interface to communicate with DRV8243 and stm32f401re MCU. While reading and writing to the registers facing an issue. And also please clarify some of my doubts regarding…
