BQ24232RGTT 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; monitors 10 kΩ NTC thermistor for battery pack temperature sensing. |
| 2 | BAT | bidirectional | Charger power stage output and battery voltage sense input; bypass to VSS with 4.7 μF to 47 μF ceramic capacitor. |
| 3 | BAT | bidirectional | Charger power stage output and battery voltage sense input; bypass to VSS with 4.7 μF to 47 μF ceramic capacitor. |
| 4 | CE | input | Charge enable active-low input; internally pulled down ~285 kΩ; high disables charging, low enables charger. |
| 5 | EN2 | input | Input current limit configuration input; used with EN1 to control maximum input current and USB compliance; internally pulled down ~285 kΩ. |
| 6 | EN1 | input | Input current limit configuration input; used with EN2 to control maximum input current and USB compliance; internally pulled down ~285 kΩ. |
| 7 | PGOOD | output | Open-drain power good status indication output; pulls to VSS when valid input source detected, high-impedance otherwise. |
| 8 | VSS | power_in | Ground; connect to thermal pad and to the ground rail of the circuit. |
| 9 | CHG | output | Open-drain charging status indication output; pulls to VSS when battery is charging, high impedance when complete or disabled. |
| 10 | OUT | output | System supply output; provides regulated output when input is below OVP threshold; bypass to VSS with 4.7 μF to 47 μF ceramic capacitor. |
| 11 | OUT | output | System supply output; provides regulated output when input is below OVP threshold; bypass to VSS with 4.7 μF to 47 μF ceramic capacitor. |
| 12 | ILIM | input | Adjustable current limit programming input; connect 3.1 kΩ to 7.8 kΩ resistor to VSS to program maximum input current when EN2=1, EN1=0. |
| 13 | IN | input | Input power connection; operating range 4.35 V to 6.6 V; accepts up to 26 V without damage; use 1 μF to 10 μF bypass capacitor to VSS. |
| 14 | TMR | input | Timer programming input; controls precharge and fast-charge safety timers; connect 18 kΩ to 72 kΩ resistor to VSS for desired timer length. |
| 15 | ITERM | input | Termination current programming input; connect 0 Ω to 15 kΩ resistor to VSS to program user-programmable termination current threshold. |
| 16 | ISET | bidirectional | Fast-charge current programming input and charge current output; connect 1.8 kΩ to 36 kΩ resistor to VSS to program fast-charge current. |
| 17 | Thermal Pad | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
