Hi All,
I'm an Engineer at a small firm that does automotive instrumentation. I saw the PMP9755 demo board which uses a super cap and a boost converter to provide backup power, and felt this could be a great solution to brown out power backup.

Hi Abhay,
The bq33100 is a supercap monitor that for 2 or more supercapacitors in series.
This device is not suitable for single capacitor operation.
The following TI design may be of interest: http://www.ti.com/tool/pmp9755

you can refer to the reference design PMP9755
1. Add a schottky diode in parallel with the TPS54540 to prevent current flowing to 8V~32V rail through the MOSFET body diode when there is no voltage in the 8V~32V rail.
2. if both device are enabled, you…
