PIN | I/O | DESCRIPTION | ||
---|---|---|---|---|
NAME | NO. | |||
bq24080-Q1 | bq24081-Q1 | |||
CE | 9 | – | I | Charge enable input (active-low) |
GND | 2, 7 | 2, 7 | – | Ground |
IN | 1 | 1 | I | Adapter dc voltage. Connect minimum 0.1-μF capacitor to VSS. |
ISET | 6 | 6 | I | Charge current. External resistor to VSS sets precharge and fast-charge current, and also the termination current value. Can be used to monitor the charge current. |
OUT | 10 | 10 | O | Charge current output. Connect minimum 0.1-μF capacitor to VSS. |
PG | 8 | – | O | Power-good status output (open-drain) |
STAT1 | 3 | 3 | O | Charge status outputs (open-drain) |
STAT2 | 4 | 4 | O | |
TE | – | 8 | I | Timer-enable input (active-low) |
TS | – | 9 | I/O | Temperature sense; connect to NTC in battery pack. |
VSS | 5 | 5 | – | Ground |
Thermal pad | – | – | – | There is an internal electrical connection between the exposed thermal pad and the VSS pin of the device. The exposed thermal pad must be connected to the same potential as the VSS pin on the printed-circuit board. Do not use the thermal pad as the primary ground input for the device. The VSS pin must be connected to ground at all times. |
