BQ24232HRGTR 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 that monitors a 10-kΩ NTC in the battery pack; for applications without TS use, connect a 10-kΩ fixed resistor from TS to VSS. |
| 2 | BAT | bidirectional | Charger power stage output and battery voltage sense input; connect to the positive battery terminal and bypass to VSS with a 4.7-μF to 47-μF ceramic capacitor. |
| 3 | BAT | bidirectional | Charger power stage output and battery voltage sense input; connect to the positive battery terminal and bypass to VSS with a 4.7-μF to 47-μF ceramic capacitor. |
| 4 | CE | input | Active-low charge enable; a high level places the charger in standby, a low level enables charging, and CE is internally pulled down with about 285 kΩ and must not be left unconnected. |
| 5 | EN2 | input | Input current limit configuration input that sets the maximum input current and enables USB compliance together with EN1; internally pulled down with about 285 kΩ and must not be left unconnected. |
| 6 | EN1 | input | Input current limit configuration input that sets the maximum input current and enables USB compliance together with EN2; internally pulled down with about 285 kΩ and must not be left unconnected. |
| 7 | PGOOD | output | Open-drain power good output that pulls to VSS when a valid input source is detected; connect through a 1-kΩ to 100-kΩ resistor to the logic rail or use with an LED. |
| 8 | VSS | power_in | Ground connection that must be tied to the thermal pad and to the circuit ground rail. |
| 9 | CHG | output | Open-drain charging status output that pulls to VSS while charging and is high impedance when charging is complete or the charger is disabled. |
| 10 | OUT | output | System supply output that regulates when the input is within range and connects to VBAT when the input is out of range; bypass to VSS with a 4.7-μF to 47-μF ceramic capacitor. |
| 11 | OUT | output | System supply output that regulates when the input is within range and connects to VBAT when the input is out of range; bypass to VSS with a 4.7-μF to 47-μF ceramic capacitor. |
| 12 | ILIM | input | Adjustable input current limit programming input; connect a 3.1-kΩ to 7.8-kΩ resistor from ILIM to VSS to set the maximum input current in EN2=1, EN1=0 mode. |
| 13 | IN | power_in | Input power connection to the DC supply (AC adapter or USB); the '232H operating range is 4.35 V to 10.2 V, the input accepts up to 26 V without damage but operation is suspended, and a 1-μF to 10-μF bypass capacitor to VSS is required. |
| 14 | TMR | input | Timer programming input; connect an 18-kΩ to 72-kΩ resistor from TMR to VSS to set the safety timers, connect to VSS to disable them, or leave unconnected for the 5-hour fast-charge and 30-minute precharge defaults. |
| 15 | ITERM | input | Termination current programming input; connect a 0-Ω to 15-kΩ resistor from ITERM to VSS to set the termination current, or leave unconnected for the internal 10% default threshold. |
| 16 | ISET | bidirectional | Fast-charge current programming input; connect a 1.74-kΩ to 34.8-kΩ resistor from ISET to VSS, since charging is disabled if ISET is left unconnected, and the voltage at ISET reflects the charge current. |
| 17 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
