XTB1056L420AD3CT from XTX, in a DFN-8(2x2). 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 | VIN | power_in | Power input accepting up to 28V maximum, with charging disabled when the input exceeds the OVP threshold (6.8V for this L variant). |
| 2 | PPR | output | Open-drain power-presence indicator that stays low while the input voltage is within the operating range and is high impedance otherwise. |
| 3 | CHG | output | Open-drain charge indicator that stays low during the charging state and is high impedance otherwise. |
| 4 | EN | input | Active-low enable input that turns the charger on or off, as shown in the typical application circuit. |
| 5 | GND | power_in | Ground, connected to the RIREF and RIMIN resistors and to the battery negative terminal. |
| 6 | IMIN | passive | Connects an external resistor (RIMIN) to GND to program the end-of-charge current. |
| 7 | IREF | passive | Connects an external resistor (RIREF) to GND to program the charge current. |
| 8 | BAT | power_out | Battery connection for the single-cell Li-ion battery, charged with a 4.2V float voltage in this variant. |
