BQ24075TRGTT 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 with resistor divider from VIN to GND for battery pack temperature monitoring; set divider to 20% for disabled TS function. |
| 2 | BAT | passive | Charger power stage output and battery voltage sense input; bypass to VSS with 4.7μF to 47μF ceramic capacitor. |
| 3 | BAT | passive | Charger power stage output and battery voltage sense input; bypass to VSS with 4.7μF to 47μF ceramic capacitor. |
| 4 | CE | input | Charge enable active-low input internally pulled down ~285kΩ; pull low to enable battery charger, pull high for standby mode. |
| 5 | EN2 | input | Input current limit configuration input internally pulled down ~285kΩ; use with EN1 to control maximum input current and enable USB compliance. |
| 6 | EN1 | input | Input current limit configuration input internally pulled down ~285kΩ; use with EN2 to control maximum input current and enable USB compliance. |
| 7 | PGOOD | output | 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 pin with internal electrical connection to exposed thermal pad; connect thermal pad to circuit ground. |
| 9 | CHG | output | Open-drain charging status indication output; pulls to VSS when battery charging, high-impedance when charging complete, flashes ~2Hz for timer fault. |
| 10 | OUT | output | System supply output regulated to 5.5V when input below OVP threshold and above regulation voltage; bypass to VSS with 4.7μF to 47μF ceramic capacitor. |
| 11 | OUT | output | System supply output regulated to 5.5V when input below OVP threshold and above regulation voltage; 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 (EN2=1, EN1=0). |
| 13 | IN | power_in | Input power connection for external DC supply (AC adapter or USB port); operating voltage range 4.35V to 6.6V; bypass to VSS with 1μF to 10μF ceramic capacitor. |
| 14 | TMR | input | Timer programming input; connect 18kΩ to 72kΩ resistor from TMR to VSS for custom timer duration, connect to VSS to disable timers, or leave unconnected for default values. |
| 15 | SYSOFF | input | System enable input internally pulled up to VBAT through ~5MΩ resistor; pull high to turn off FET Q2 disconnecting battery from system output, pull low for normal operation. |
| 16 | ISET | bidirectional | Fast charge current programming input and current monitor output; connect 590Ω to 3kΩ resistor from ISET to VSS to program fast charge current; voltage on ISET reflects actual charging current. |
| 17 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
