BQ40Z80: Shutdown behaviors and indication

Barrett Bryan

Part Number: BQ40Z80

I have a few questions regarding shutdown with the BQ40Z80:

  1. Is there an signal that will tell my MICRO that it’s in shutdown? Does PBI (pin 31) go to zero when in shutdown?
  2. If I command shutdown via the Shutdown Present Input (pin 17), will PBI also turn off?
  3. If I command shut down via the Shutdown Present Input (pin 17),will it latch off?
  4. Once in shut down, will a voltage at the PACK input (pin 25) will wake it up?
