XL2026-1 from XINLUDA, in a SOP-8. 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 | ENA | input | Logic-compatible enable input for switch A; on the XL2026-1 it is active high, with the switch on at VENA ≥ 2.4 V and off at VENA ≤ 0.8 V. |
| 2 | FLGA | output | Active-low, open-drain fault flag for switch A that asserts on overcurrent or thermal shutdown, with overcurrent asserted only after the flag response delay (typically 3 ms per the functional description). |
| 3 | FLGB | output | Active-low, open-drain fault flag for switch B that asserts on overcurrent or thermal shutdown, with overcurrent asserted only after the flag response delay (typically 3 ms per the functional description). |
| 4 | ENB | input | Logic-compatible enable input for switch B; on the XL2026-1 it is active high, with the switch on at VENB ≥ 2.4 V and off at VENB ≤ 0.8 V. |
| 5 | OUTB | output | Power output of switch B, the source of its output MOSFET, which is internally current limited. |
| 6 | GND | power_in | Ground connection for the device. |
| 7 | IN | power_in | Switch and logic supply input operating from 2.7 V to 5.5 V, which is also the drain of the output MOSFETs. |
| 8 | OUTA | output | Power output of switch A, the source of its output MOSFET, which is internally current limited. |
