BQ24075TRGTR from Texas Instruments, in a VQFN-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 connected to battery pack temperature monitoring resistor divider from VIN to GND. |
| 2 | BAT | power_in | Charger power stage output and battery voltage sense input connected to positive terminal of battery; bypass to VSS with 4.7μF to 47μF ceramic capacitor. |
| 3 | BAT | power_in | Charger power stage output and battery voltage sense input connected to positive terminal of battery; bypass to VSS with 4.7μF to 47μF ceramic capacitor. |
| 4 | CE | input | Charge enable active-low input with ~285kΩ internal pull-down; connect high to disable charging or low to enable charging. |
| 5 | EN2 | input | Input current limit configuration input with ~285kΩ internal pull-down; use EN1 and EN2 to control maximum input current and USB compliance modes per Table 1. |
| 6 | EN1 | input | Input current limit configuration input with ~285kΩ internal pull-down; use EN1 and EN2 to control maximum input current and USB compliance modes per Table 1. |
| 7 | PGOOD | tri_state | Open-drain power good status indication output; pulls to VSS when valid input source detected (VBAT + VIN-DT < VIN < VOVP). |
| 8 | VSS | power_in | Ground connection to thermal pad and printed circuit board ground rail. |
| 9 | CHG | tri_state | Open-drain charging status indication output; pulls to VSS when battery is charging, flashes at 2Hz to indicate timer fault. |
| 10 | OUT | power_out | System supply output regulated to 5.5V; bypass to VSS with 4.7μF to 47μF ceramic capacitor. |
| 11 | OUT | power_out | System supply output regulated to 5.5V; bypass to VSS with 4.7μF to 47μF ceramic capacitor. |
| 12 | ILIM | input | Adjustable current limit programming input; connect 1.07kΩ to 7.5kΩ resistor from ILIM to VSS to program maximum input current 200mA to 1.5A (EN2=1, EN1=0). |
| 13 | IN | power_in | Input power connection from AC adapter or USB port with 4.35V to 6.6V operating range; bypass to VSS with 1μF to 10μF ceramic capacitor. |
| 14 | TMR | input | Timer programming input; connect 18kΩ to 72kΩ resistor between TMR and VSS to program pre-charge and fast-charge safety timer duration. |
| 15 | SYSOFF | input | System enable input with ~5MΩ internal pull-up to VBAT; connect high to disconnect battery from system output and disable charging. |
| 16 | ISET | input | Fast charge current programming input; connect 590Ω to 3kΩ resistor from ISET to VSS to program fast charge current level, voltage reflects actual charge current during operation. |
| 17 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
