Hi,
We have developed a DRV8353RS EVK based custom board. In that, we have successfully communicated to DRV8353RS via SPI & Set "0x20h" value in "Control Register 2" register for 1x PWM Mode.
The PWM is applied to the INHA pin. But the BLDC motor is not run. While testing we found the "Status Register 0" holds the value is "0x400"(Fault register is set) & the "Status Register 1" has "0x40"( Indicates VCP charge pump and/or VGLS Undervoltage fault condition ).
We have checked the DRV controller input voltage is 24V. The VCP voltage is (with respect to Vdrain) 1.7V & VGLS voltage(with respect to Ground) 2.6V.
Could you help us to debug this issue?. If you required schematic then we will share you.
Regards,
Suresh.
