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 Hello experts,
Hope you are doing well.
Our customer have some questions:
1. What is the time or time stage it takes for the chip to overcurrent from Iout to Toff shutdown in response from Itrip? (from comparator to core output…
Part Number: DRV8243-Q1 Hello experts,
Hope you are doing well.
Our customer encountered a problem when utilize DRV8243-Q1 in thermal management project:
When they utilize heat guns to detect over temperature fault, but the device didn't report the…

Part Number: DRV8243-Q1 Other Parts Discussed in Thread: DRV8718-Q1 Hello team,
My customer have questions on DRV8243-Q1(hardware version) and DRV8718-Q1(SPI version).
1. For DRV8243-Q1, SLEEP pin is always pulled high all the time, but the MCU is on…
Part Number: DRV8243-Q1 Hi team,
Customer found in VM=1.5V, DRVOFF=5V, nSleep=0V, IC no output.
When pull up nSleep to 5V, SDO= 3V
Because in customer system DRV8243 SPI is combined with TCAN1145 (SDI/SDO/SCLK), because SDO is abnormal (3V), the SPI…
Part Number: DRV8243-Q1 Hi
Our customers are unable to transition the chip from sleep to standby mode when using DRV8243.
Based on the above questions, I asked the client to consider four aspects and provided the following responses:
1. Our SPI format…
Part Number: DRV8243-Q1 There is a special working condition:
When DRV8243 is in sleep state, MCU output a square wave of 400kHz to DRVOFF pin, what is the effect to DRV8243? Is there any damage to the performance of the device?
Thank you.
