BQ24074RGTR from Texas Instruments, in a QFN-16-EP(3x3). 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 | TS | input | External NTC thermistor input for battery temperature monitoring; nominal 10 kΩ thermistor. |
| 2 | BAT | bidirectional | Battery positive terminal providing charging current output and battery voltage sensing input; bypass with 4.7 μF to 47 μF ceramic capacitor. |
| 3 | BAT | bidirectional | Battery positive terminal providing charging current output and battery voltage sensing input; bypass with 4.7 μF to 47 μF ceramic capacitor. |
| 4 | CE | input | Charge enable active-low control input; connect low to enable charging, high to disable with internal 285 kΩ pulldown. |
| 5 | EN2 | input | Input current limit configuration input; use with EN1 to set USB compliance mode with internal 285 kΩ pulldown. |
| 6 | EN1 | input | Input current limit configuration input; use with EN2 to set USB compliance mode with internal 285 kΩ pulldown. |
| 7 | PGOOD | tri_state | Open-drain power good status output; pulls to VSS when valid input source detected (4.35 V < VIN < 10.8 V for BQ24074). |
| 8 | VSS | power_in | Ground connection; connect to circuit ground and thermal pad at all times. |
| 9 | CHG | tri_state | Open-drain charging status output; pulls to VSS when battery is charging, high impedance when complete. |
| 10 | OUT | power_out | System regulated power supply output; 4.4 V when valid input present; bypass with 4.7 μF to 47 μF ceramic capacitor. |
| 11 | OUT | power_out | System regulated power supply output; 4.4 V when valid input present; bypass with 4.7 μF to 47 μF ceramic capacitor. |
| 12 | ILIM | input | Adjustable input current limit programming input; connect 1.1 kΩ to 8 kΩ resistor to VSS for 200 mA to 1.5 A limit. |
| 13 | IN | power_in | Power input connection; 4.35 V to 10.5 V operating range, accepts up to 26 V without damage; bypass with 1 μF to 10 μF capacitor. |
| 14 | TMR | input | Pre-charge and fast-charge timer programming input; connect 18 kΩ to 72 kΩ resistor to VSS for desired timer duration. |
| 15 | ITERM | input | Termination current programming input (BQ24074 only); connect 0 Ω to 15 kΩ resistor to VSS to set termination threshold. |
| 16 | ISET | bidirectional | Fast charge current programming input; connect 590 Ω to 8.9 kΩ resistor to VSS; voltage output monitors actual charge current. |
| 17 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
