The leads should be shorted together or the device placed in conductive foam during storage or handling to prevent electrostatic damage to the MOS gates. TSSOP (DBT) (TOP VIEW) TERMINAL FUNCTIONS TERMINAL I/O(1) DESCRIPTION NO. NAME 1 VIN I Voltage measurement input from the AFE 2 TS1 I 1st Thermistor voltage input connection to monitor temperature 3 TS2 I 2nd Thermistor voltage input connection to monitor temperature 4 PU O Output to pull up the PRES pin for system detection 5 PRES I Active low input to sense system insertion and typically requires additional ESD protection 6 SCLK I/OD Communication clock to the AFE 7 SAFE O Active high output to enforce additional level of safety protection; e.g., fuse blow. (Inverse of pin 12) 8 VDDD P Positive supply for digital circuitry and I/O pins Backup power to the bq20z80 data registers during periods of low operating voltage. RBI accepts a 9 RBI P storage capacitor or a battery input. 10 SDATA I/O Data transfer to and from the AFE 12 SAFE O Active low output to enforce additional level of safety protection; e.g., fuse blow. (Inverse of pin 7) 13 NC – Not used— leave floating 14 NC – Not used— leave floating 15 SMBC I/OD SMBus clock open-drain bidirectional pin used to clock the data transfer to and from the bq20z80 16 SMBD I/OD SMBus data open-drain bidirectional pin used to transfer address and data to and from the bq20z80 Display control for the LEDs. This pin is typically connected to bq29312A REG via a 100-k Ω resistor 17 DISP I and a push-button switch to VSSD. Active low input to detect secondary protector output status and allows the bq20z80 to report the 18 PFIN I status of the 2nd level protection output 20 LED5 O LED5 display segment that drives an external LED depending on the firmware configuration 21 LED4 O LED4 display segment that drives an external LED depending on the firmware configuration (1) I = Input, IA = Analog input, I/O = Input/output, I/OD = Input/Open-drain output, O = Output, OA = Analog output, P = Power 2 |
