XTB1056L420AD3CT

XTX · Battery Management · DFN-8(2x2)

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.
