NAME 1 NC – Not used— leave floating 2 XALERT I Input from bq29330 XALERT output. 3 SDATA I/O Data transfer to and from bq29330 4 SCLK I/O Communication clock to the bq29330 5 CLKOUT O 32.768-kHz output for the bq29330. This pin should be directly connected to the AFE. 6 TS1 I 1st Thermistor voltage input connection to monitor temperature 7 TS2 I 2nd Thermistor voltage input connection to monitor temperature 8 PRES I 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 9 PFIN I the status of the 2nd level protection output 10 SAFE OD 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 11 SMBD I/OD bq20z60-R1 12 NC – Not used— leave floating 13 SMBC I/OD 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 100K Ω resistor 14 DISP I and a push button switch connect to VSS 15 NC – Not used— leave floating 16 LED1 O LED1 display segment that drives an external LED depending on the firmware configuration 17 LED2 O LED2 display segment that drives an external LED depending on the firmware configuration 18 LED3 O LED3 display segment that drives an external LED depending on the firmware configuration 19 LED4 O LED4 display segment that drives an external LED depending on the firmware configuration 20 LED5 O LED5 display segment that drives an external LED depending on the firmware configuration 21 VSS – Negative supply voltage (1) I = Input, IA = Analog input, I/O = Input/output, I/OD = Input/Open-drain output, O = Output, P = Power Copyright © 2009, Texas Instruments Incorporated Submit Documentation Feedback 3 Product Folder Link(s) :bq20z60-R1 |
