Part Number: DRV8308
Application: Sensored BLDC driver for consumer electronic product
Question type: Development and troubleshooting
Description of the problem: Hi, I was using DRV8307 to run my BLDC, it worked fine. When I upgraded to DRV8308 the VREG in the chip is not coming up. I have checked for shorts in bypass capacitors, and pullup pulldown resistors, nothing is short. Programming is clear from the microcontroller side (SPI registers are written properly). Voltage at VINT is about 1.3V. VM is 15V. Enable pins state is not changing the VREG state (it is always 0V )
Thanks.
