Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | N/C | unconnected | No connect; this pin must be left floating. |
| 2 | IN | power_in | Input voltage that provides the charging voltage for the battery; recommended VIN range is 4.5 V to 10 V, absolute maximum 13.5 V with respect to GND. |
| 3 | IN | power_in | Input voltage that provides the charging voltage for the battery; recommended VIN range is 4.5 V to 10 V, absolute maximum 13.5 V with respect to GND. |
| 4 | VCC | power_in | Supply voltage; recommended range 4.5 V to 10 V, absolute maximum 13.5 V with respect to GND. |
| 5 | ISNS | input | Current sense input; an external sense resistor between this pin and the charge path sets the magnitude of the constant charge current. |
| 6 | N/C | unconnected | No connect; this pin must be left floating. |
| 7 | APG/THERM | input | Adapter power-good input and thermistor sense input, with a falling-edge deglitch of 25 µs to 75 µs. |
| 8 | TMR EN | input | Active-high charge-enable input with an internal 100 kΩ to 200 kΩ pulldown (high-level 2.25 V min, low-level 0.8 V max); low enables the low-current standby mode. |
| 9 | VSEL | input | Selects 4.1 V or 4.2 V charge regulation per cell (high = 4.2 V, low = 4.1 V); logic inputs with 2.25 V min high, 0.8 V max low, and an internal 100 kΩ to 200 kΩ pulldown. |
| 10 | GND/HEATSINK | power_in | Ground pin; connect to the PowerPAD heat-sink layout pattern. |
| 11 | N/C | unconnected | No connect; this pin must be left floating. |
| 12 | CR | passive | Internal regulator bypass capacitor node; the output is 2.81 V to 2.88 V with a 0.22 µF capacitor connected. |
| 13 | TMR SEL | input | Charge timer selection input; high-level 2.7 V min, low-level 0.6 V max, input bias current 15 µA max at VI ≤ 5 V. |
| 14 | STAT1 | output | Status display output 1; output sink/source current is limited to 10 mA maximum. |
| 15 | STAT2 | output | Status display output 2, available on the bq24008 only; output sink/source current is limited to 10 mA maximum. |
| 16 | AGND | power_in | Ground pin; connect close to the negative battery terminal. |
| 17 | VSENSE | input | Battery voltage sense input used to regulate the charge voltage. |
| 18 | OUT | output | Charge current output; output current is limited to 2 A absolute maximum and 1.2 A continuous. |
| 19 | OUT | output | Charge current output; output current is limited to 2 A absolute maximum and 1.2 A continuous. |
| 20 | N/C | unconnected | No connect; this pin must be left floating. |
| 21 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
