PRODUCTION DATA
Some device pins may not be needed in a particular application. The manner in which each should be terminated in this case is described below.
Pin | Name | Recommendation |
---|---|---|
1–5, 19, 20 | VC0–VC5 | Cell inputs 1 and 5 should always be connected to actual cells, with cells connected between VC1 and VC0, and between VC4A and VC5. VC0 should be connected through a resistor and capacitor on the PCB to pin 11 (VSS). Pins VC3A and VC3B should be shorted together on the PCB. Pins VC4A and VC4B should be shorted together on the PCB. Pins related to unused cells (which may be cell 2 – cell 4, pins 1–3, 19, 20) should be shorted directly to an adjacent VC pin. All VC pins should be connected to either an adjacent VC pin or an actual cell (through R and C). |
6, 7 | SRP, SRN | If not used, these pins should be connected to pin 11 (VSS). |
8 | TS | If not used, this pin should be connected to pin 11 (VSS). |
9, 10 | DSG, CHG | If not used, these pins should be left floating. |
12, 13 | SCL, SDA | If not used, these pins should be connected to pin 11 (VSS). |
14, 15 | ALERT, REGOUT | If not used, these pins should be left floating. |
16 | REGSRC | If the REGOUT regulator nor the CHG and DSG drivers are used, this pin should be connected to pin 17 (BAT). |
