BOOSTXL-DRV3245AQ1: Basic turn on

Part Number: BOOSTXL-DRV3245AQ1

I am unable to switch a FET on by setting a 3.3V signal on INHA for example.

I powered up the board with 24V, connected 3.3V, GND, nSCS, SDI, SDO and EN pin.

The GHx are around 5.8V. No error indication on nFault or inside the SPI registers.

Except, the "Voltage Regulator Control Register (Address = 0x0B)" is toggling between:

CP_SD_MODE = 1
   CP_DIS = 1
   VREF_SCALE = 1
   RSVD = 63

and

   CP_SD_MODE = 0
   CP_DIS = 0
   VREF_SCALE = 1
   RSVD = 0

Hi Stephan,

Quick update for you - I have looked into this and am still following up with my team to investigate further. In the meantime, I have some questions and feedback I can provide through email.

Do you have an email address that I can contact you at directly?

This DRV3245-Q1 device is a functional safety part, so I am limited in what information I can share over the public e2e forum.

On the topic of functional safety, have you or your company already signed a SafetyNDA with Texas Instruments?

Thanks and Best Regards,
Andrew
