Texas Instruments · Battery Management · VQFN-24(4x4)
BQ24168RGER from Texas Instruments, in a VQFN-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 | N.C. | unconnected | Shown as N.C. in the RGE top view for the BQ24161/BQ24168 pinout, and Table 6-1 gives no function for this pin. |
| 2 | PSEL | input | USB source-detection input: high starts the USB input at a 100 mA limit and low at 1.5 A, it has no effect on IN, and it must not be left unconnected. |
| 3 | SCL | input | I2C interface clock; connect to the logic rail through a 10-kΩ resistor. |
| 4 | SDA | bidirectional | I2C interface data; connect to the logic rail through a 10-kΩ resistor. |
| 5 | PGND | power_in | Ground terminal; connect to the thermal pad and the circuit ground plane, and keep it connected to ground at all times. |
| 6 | DRV | power_out | Gate-drive bias supply for the internal MOSFETs; bypass to PGND with a 1-µF ceramic capacitor, and it may drive external loads up to 10 mA. |
| 7 | INT | output | Open-drain status and interrupt output that pulls low during charging and sends a 128-µs fault pulse; connect through 100 kΩ to a logic rail, with 1 mA maximum sink current. |
| 8 | STAT | output | Open-drain charge-status and interrupt output that pulls low during charging; pull up through an LED or 10 kΩ, with 10 mA maximum sink current. |
| 9 | TS | input | Battery NTC monitor input; connect to the center tap of a resistor divider from DRV to GND with the NTC from TS to GND, or tie to DRV to disable the TS function. |
| 10 | BGATE | output | Gate drive for an external P-channel discharge MOSFET; it is low in high-impedance mode and when no input is connected. |
| 11 | BAT | bidirectional | Battery connection to the positive battery terminal; bypass BAT to GND with at least 1 µF. |
| 12 | BAT | bidirectional | Battery connection to the positive battery terminal; bypass BAT to GND with at least 1 µF. |
| 13 | SYS | power_out | System voltage sense and charger FET connection; connect at the output bulk capacitors, bypass with at least 10 µF, and 47 µF is recommended for optimal transient response. |
| 14 | SYS | power_out | System voltage sense and charger FET connection; connect at the output bulk capacitors, bypass with at least 10 µF, and 47 µF is recommended for optimal transient response. |
| 15 | PGND | power_in | Ground terminal; connect to the thermal pad and the circuit ground plane, and keep it connected to ground at all times. |
| 16 | PGND | power_in | Ground terminal; connect to the thermal pad and the circuit ground plane, and keep it connected to ground at all times. |
| 17 | PGND | power_in | Ground terminal; connect to the thermal pad and the circuit ground plane, and keep it connected to ground at all times. |
| 18 | SW | output | Inductor connection to the switched side of the external inductor; absolute maximum pin range is -0.7 V to 12 V and continuous output current is 4.5 A. |
| 19 | BOOT | input | High-side MOSFET gate-driver supply; connect a 0.01-µF ceramic capacitor rated above 10 V from BOOT to SW, with BOOT-to-SW maximum 7 V. |
| 20 | PMIDI | output | Reverse-blocking and high-side MOSFET connection point for the high-power input; bypass with at least 4.7 µF, and it is not current limited so any short will damage the IC. |
| 21 | IN | power_in | Input supply from the AC adapter or alternate source; BQ24168 IN operating range is 4.2 V to 6 V, and bypass to PGND with at least 1 µF. |
| 22 | USB | power_in | USB input supply from the USB port or adapter; BQ24168 USB operating range is 4.2 V to 6 V, and bypass to PGND with at least 1 µF. |
| 23 | PMIDU | output | Reverse-blocking and high-side MOSFET connection point for the USB input; bypass with at least 4.7 µF, and it is not current limited so any short will damage the IC. |
| 24 | CD | input | IC hardware chip disable; drive high for high-impedance mode and low for normal operation, and do not leave it unconnected. |
| 25 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
