BQ24230RGTR 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 for battery pack temperature monitoring; monitor 10-kΩ NTC thermistor or connect 10-kΩ fixed resistor to VSS if not utilized. |
| 2 | BAT | bidirectional | Charger power stage output and battery voltage sense input; connect to positive battery terminal and bypass with 4.7-μF to 47-μF ceramic capacitor to VSS. |
| 3 | BAT | bidirectional | Charger power stage output and battery voltage sense input; connect to positive battery terminal and bypass with 4.7-μF to 47-μF ceramic capacitor to VSS. |
| 4 | CE | input | Charge enable active-low input; connect high to disable battery charging, low to enable charger; internally pulled down with ~285 kΩ. |
| 5 | EN2 | input | Input current limit configuration input used with EN1 to control maximum input current and enable USB compliance; internally pulled down with ~285 kΩ. |
| 6 | EN1 | input | Input current limit configuration input used with EN2 to control maximum input current and enable USB compliance; internally pulled down with ~285 kΩ. |
| 7 | PGOOD | tri_state | Open-drain power good status indication output; pulls to VSS when valid input source detected (VBAT + VIN(DT) < VIN < VOVP), high-impedance when input power out of specified limits. |
| 8 | VSS | power_in | Ground; connect to thermal pad and to ground rail of the circuit. |
| 9 | CHG | tri_state | Open-drain charging status indication output; pulls to VSS when battery is charging, high impedance when charging complete or charger disabled. |
| 10 | OUT | power_out | System supply output providing regulated output when input below OVP threshold and above regulation voltage, connected to VBAT when out of operation range; bypass with 4.7-μF to 47-μF ceramic capacitor to VSS. |
| 11 | OUT | power_out | System supply output providing regulated output when input below OVP threshold and above regulation voltage, connected to VBAT when out of operation range; bypass with 4.7-μF to 47-μF ceramic capacitor to VSS. |
| 12 | ILIM | input | Adjustable current limit programming input; connect 3.1-kΩ to 7.8-kΩ resistor to VSS for programmable mode (EN2=1, EN1=0), leaving unconnected disables all charging. |
| 13 | IN | power_in | Input power connection for external DC supply (USB port or AC adapter); operating range 4.35 V to 6.6 V, accepts up to 26 V without damage but operation suspended; bypass with 1-μF to 10-μF capacitor to VSS. |
| 14 | TMR | input | Timer programming input for precharge and fast-charge safety timers; connect to VSS to disable all timers, or 18-kΩ to 72-kΩ resistor to VSS to program duration, leave unconnected for 5-hour fast-charge and 30-minute precharge defaults. |
| 15 | TD | input | Termination disable input for bq24230; connect high to disable charger termination and safety timers, or low to enable termination; internally pulled down with ~285 kΩ. |
| 16 | ISET | bidirectional | Fast-charge current programming input; connect 1.8-kΩ to 36-kΩ resistor to VSS to program fast-charge current level, or monitor voltage to reflect actual charging current (1/400 of IBAT); leaving unconnected disables charging. |
| 17 | PAD | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
