Input from bq29330 XALERT output.
Data transfer to and from bq29330
Communication clock to the bq29330
32.768-kHz output for the bq29330. This pin should be directly connected to the AFE.
1^st Thermistor voltage input connection to monitor temperature
2^nd Thermistor voltage input connection to monitor temperature
Active low input to sense system insertion. Typically requires additional ESD protection.
Active low input to detect secondary protector output status, and to allow the bq20z60-R1 to report
the status of the 2^nd level protection output
Active high output to enforce additional level of safety protection; e.g., fuse blow.
SMBus data open-drain bidirectional pin used to transfer address and data to and from the
bq20z60-R1
Not used— leave floating
SMBus clock open-drain bidirectional pin used to clock the data transfer to and from the bq20z60-R1
Display control for the LEDs. This pin is typically connected to bq29330 REG via a 100KΩ resistor
and a push button switch connect to VSS
Not used— leave floating
LED1 display segment that drives an external LED depending on the firmware configuration
LED2 display segment that drives an external LED depending on the firmware configuration
LED3 display segment that drives an external LED depending on the firmware configuration
LED4 display segment that drives an external LED depending on the firmware configuration
LED5 display segment that drives an external LED depending on the firmware configuration
