Part Number: BQ25601

Hello,

Quick check about the questions below, thanks in advance.

  1. Can BQ25601 Tj temperature be read by SW? There is no register for temperature per datasheet.
  2. What will happen when BQ25601 Tj reach 110C/90C/160C?  

                Is it hardware action or need SW action?

                Does these actions need special pin connections or no external pin needed

3. Can BQ25601 enter shipmode by SW command? What will BQ25601 shipmode do? Should QON pin connected?

4.Can BQ25601 enter full system reset by SW command? What will BQ25601 full system reset do? Should QON pin connected?

    Hi,

    1. No.

    2. Please refer to 8.3.10.3 Thermal Regulation and Thermal Shutdown on the d/s. No hardware or external pin is needed.

    3. Please refer to 8.3.8.1 BATFET Disable Mode (Shipping Mode) on the d/s. When the host set BATFET_DIS bit, the charger can turn off BATFET immediately or delay by tSM_DLY as configured by BATFET_DLY bit. /QON connection does not matter because /QON is for exiting shipping mode only.

    4. Full system reset is supported by /QON pin. Please refer to 8.3.8.3 BATFET Full System Reset and 8.3.8.4 QON Pin Operations on the d/s.

    Thanks,

    Ning.
