MAX17260SETD+ from Maxim Integrated, in a TDFN-14-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 | TH | passive | Thermistor input: connect a thermistor from TH to GND, and connect TH to BATT if not used; TH also provides battery insertion/removal detection. |
| 2 | NC | unconnected | No connection. |
| 3 | NC | unconnected | No connection. |
| 4 | NC | unconnected | No connection. |
| 5 | NC | unconnected | No connection. |
| 6 | BATT | power_in | IC power supply and battery voltage sense input, connected to the positive cell terminal and bypassed with a 0.1µF capacitor to GND. |
| 7 | CSN | input | Sense resistor negative sense point: Kelvin connect to the system side for a low-side application or the cell side for a high-side application, as determined by measuring CSN voltage at start-up. |
| 8 | GND | power_in | IC ground. |
| 9 | CSPL | input | Low-side sense resistor positive sense point, Kelvin connected to the cell side of the sense resistor. |
| 10 | CSPH | input | High-side sense resistor positive sense point: Kelvin connect to the system side of an external high-side sense resistor, or tie to BATT for low-side sensing. |
| 11 | REG | power_out | Internal 1.8V regulator output, bypassed with an external 0.47µF capacitor to GND; do not load externally. |
| 12 | ALRT | output | Open-drain active-low alert output indicating fuel-gauge alerts; connect to GND if not used. Absolute maximum sink current is 20mA and ALRT to GND is rated -0.3V to +17V. |
| 13 | SDA | bidirectional | Serial data input/output for the 2-wire I2C interface, open-drain driver with an internal pulldown for disconnection sensing. |
| 14 | SCL | input | Serial clock input for the 2-wire interface, input only, with an internal pulldown for disconnection sensing. |
| 15 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
