BQ24001PWP from Texas Instruments, in a HTSSOP-20. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | N/C | unconnected | No connect; this pin must be left floating. |
| 2 | IN | input | Input voltage that provides the charging voltage for the battery; recommended input voltage range is 4.5 V to 10 V. |
| 3 | IN | input | Input voltage that provides the charging voltage for the battery; recommended input voltage range is 4.5 V to 10 V. |
| 4 | VCC | power_in | Supply voltage; recommended range is 4.5 V to 10 V, with an absolute maximum of 13.5 V with respect to GND. |
| 5 | ISNS | input | Current sense input used to set the constant charge current through an external sense resistor. |
| 6 | N/C | unconnected | No connect; this pin must be left floating. |
| 7 | APG/THERM | input | Adapter power-good input and thermistor sense input; falling-edge deglitch is 25 µs minimum and 75 µs maximum. |
| 8 | EN | input | Active-high charge-enable input with internal pull-down (100 kΩ min, 200 kΩ typ); low-current standby mode is active when EN is low, with a high-level input of 2.25 V minimum and a low-level input of 0.8 V maximum. |
| 9 | VSEL | input | Charge regulation selection input that selects 4.1 V or 4.2 V per cell; high-level input 2.25 V minimum, low-level input 0.8 V maximum, internal pull-down 100 kΩ min to 200 kΩ typ. |
| 10 | GND/HEATSINK | power_in | Ground pin that must be connected 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 connection; CR output voltage is 2.816 V minimum, 2.85 V typical, 2.88 V maximum at 0 < IO < 100 µA. |
| 13 | TMR SEL | input | Charge timer selection input; high-level input 2.7 V minimum, low-level input 0.6 V maximum, input bias current 15 µA maximum at VI ≤ 5 V. |
| 14 | STAT1 | output | Charge status display output 1; output sink/source current is limited to 10 mA absolute maximum. |
| 15 | N/C | unconnected | No connect on the bq24001PWP; this pin must be left floating. |
| 16 | AGND | power_in | Analog ground pin that must be connected close to the negative battery terminal. |
| 17 | VSENSE | input | Battery voltage sense input used to regulate the charge voltage; absolute maximum input voltage is 13.5 V with respect to GND. |
| 18 | OUT | output | Charge current output; continuous output current is 1.2 A maximum and absolute maximum output current is 2 A. |
| 19 | OUT | output | Charge current output; continuous output current is 1.2 A maximum and absolute maximum output current is 2 A. |
| 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). |
