Part Number: DRV8143-Q1 hi
I am using DRV8143 SPI(S) Variant in my circuit.
There are some problem to control the chip with ESP32-S3 via SPI.
I can read Devie ID of the DRV8143 and device ID is 0xBA.
And these are all register values of the chip…
Hi Marvin,
Please see below information from the datasheet. The nSCS must go back HIGH after every frame of 16-bits or 16 SCLKs. A write operation is completed and the data written at the rising edge of the nSCS at the end of every frame. A read may…

Part Number: DRV8143-Q1 Tool/software: Hi there
I will use the DRV8143HQDGQRQ1 in my design.
In the datahsheet I did not find any information about the "Thermal Pad" of VSSOP-28 package.
Can it safely tied to GND? Or what is the recommendation…
Part Number: DRV8143-Q1 Tool/software: Hi Team,
I'm working on 2 DRV8143S-Q1 (VQFN) devices that shall work simultaneously, However the charge pump on these devices don't go above 12V. When I give HIGH signals to nSLEEP and IN, I only get 0.4V at the…
Part Number: DRV8143-Q1 Tool/software: Hi Team,
I'm trying to use the ITRIP regulation function on the device however after reaching the trip current, the device oscillates for a brief time and then shuts off due to over temperature. As you can see…

Part Number: DRV8143-Q1 Hi team,
I have a question. How can I calculate thermal under PWM setting? Even if I changed slew rate and duty cycle, the thermal doesn't look changed.
Best Regards,
