BQ25616JRTWT from Texas Instruments, in a WQFN-24(4x4). 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 | VAC | power_in | Charger input voltage sensing; an optional external n-channel ACFET is placed between VAC and VBUS, and VAC is connected to VBUS if the ACFET is not used. The ACFET turns on when VAC is below the 14.2 V ACOV threshold and above UVLO. |
| 2 | ACDRV | output | Charge pump output that drives an external N-channel ACFET, providing 6 V above VBUS as gate drive; leave floating if external OVP is not used. |
| 3 | D+ | bidirectional | Positive line of the USB data pair used for D+/D- based host/charging port detection (DCD, BC1.2 primary and secondary detection, and nonstandard adapters). |
| 4 | D- | bidirectional | Negative line of the USB data pair used for D+/D- based host/charging port detection (DCD, BC1.2 primary and secondary detection, and nonstandard adapters). |
| 5 | STAT | output | Open-drain status output that must be pulled up to a logic rail through 10 kΩ; LOW indicates charge in progress, HIGH indicates charge complete or SLEEP, and 1 Hz blinking indicates charge suspend (fault). Sink current is limited to 6 mA. |
| 6 | OTG | input | Boost mode enable pin; boost mode is enabled when pulled HIGH, and the pin must not be left floating. |
| 7 | PG | output | Open-drain active-low power-good output, pulled up through 10 kΩ; LOW indicates a good input when VIN is between UVLO and ACOV, above the SLEEP threshold, and input current limit is above 30 mA. Sink current is limited to 6 mA. |
| 8 | ILIM | input | Sets the input current limit via a resistor to ground (IINDPM = KILIM/RILIM) when the adapter is detected as unknown; acceptable range is 500 mA to 3200 mA. |
| 9 | CE | input | Charge enable pin; battery charging is enabled when this pin is driven LOW. |
| 10 | ICHG | input | Sets the charge current limit via a resistor to ground (ICHG = KICHG/RICHG); acceptable charge current range is 300 mA to 3000 mA. |
| 11 | TS | input | Battery temperature qualification input for an NTC thermistor, with a resistor divider from REGN to TS to GND; charge and boost are suspended when the TS voltage is out of range (10 kΩ resistors to REGN and GND when unused). |
| 12 | VSET | input | Sets the default battery charge voltage via a resistor to GND: float = 4.208 V, short to GND = 4.352 V, 5 kΩ to 25 kΩ = 4.100 V. |
| 13 | BAT | power_in | Battery connection to the positive terminal of the battery pack; the internal current sense resistor is between SYS and BAT, and a 10 µF capacitor should be placed close to this pin. |
| 14 | BAT | power_in | Battery connection to the positive terminal of the battery pack; the internal current sense resistor is between SYS and BAT, and a 10 µF capacitor should be placed close to this pin. |
| 15 | SYS | power_out | System output connection point; the internal current sense resistor is between SYS and BAT, and a 10 µF (min) capacitor should be placed close to this pin. |
| 16 | SYS | power_out | System output connection point; the internal current sense resistor is between SYS and BAT, and a 10 µF (min) capacitor should be placed close to this pin. |
| 17 | GND | power_in | Power ground and signal ground. |
| 18 | GND | power_in | Power ground and signal ground. |
| 19 | SW | power_out | Switching node connecting to the output inductor, internally tied to the HSFET source and LSFET drain; connect the 0.047 µF bootstrap capacitor from SW to BTST. |
| 20 | SW | power_out | Switching node connecting to the output inductor, internally tied to the HSFET source and LSFET drain; connect the 0.047 µF bootstrap capacitor from SW to BTST. |
| 21 | BTST | power_in | PWM high-side driver positive supply, connected internally to the bootstrap diode cathode; connect the 0.047 µF bootstrap capacitor from SW to BTST. |
| 22 | REGN | power_out | PWM low-side driver positive supply output, connected to the bootstrap diode anode; connect a 4.7 µF (10 V rated) ceramic capacitor from REGN to analog GND close to the IC. |
| 23 | PMID | power_out | Connected to the drain of the reverse blocking MOSFET (RBFET) and the drain of HSFET; place a 10 µF capacitor from PMID to GND. |
| 24 | VBUS | power_in | Charger input voltage; the internal RBFET is between VBUS (source) and PMID, and a 1 µF ceramic capacitor should be placed from VBUS to GND as close as possible to the device. |
| 25 | PAD | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
