tlf35584

Want to know whether it is possible to get the output voltage value from the power management chip through SPI?

Hello,

Thank you for posting in Infineon community,

It is not possible to get exact output voltage value via SPI of TLF35584 but the following registers can be used to monitor the health status of voltage regulators.
1. VMONSTAT(Voltage Monitor Status): Indicates if voltage of all regulators are ok or not
2. DEVSTAT: Indicates if regulators are enabled or disabled
3. MONSF2: Indicates UV event of regulators
4. MONSF1: Indicates OV event of regulators

Having the above registers for regulators whose voltage tolerances are so tight eliminates the need to read the exact output voltage

Thanks

Anil
