BQ32000: Backup pin connection of BQ32000

Part Number: BQ32000

Hi team,

My customer is using our BQ32000 and they have question about our RTC.

If they don't need backup supply, can they connect vback to vcc together?

  • Hi Feng bin,

    VCC/VBACK can be connected together. Ensure that the trickle charge switches remain open for this configuration. The trickle charge switches default to all-open on powerup, so as long as the trickle charge register is not modified from default startup value there should be no issues.
