**MaxLinear** · AC-DC Controllers & Regulators · SOIC-8

SP2526A-2EN from MaxLinear, in a SOIC-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 | Enable input for MOSFET switch A, active low for the SP2526A-2 variant; enable input voltage range is -0.3V to 15V. |
| 2 | FLGA | output | Active-low open-drain fault flag output for channel A, indicating current limit when ENA is active, and thermal shutdown or undervoltage in normal operation. |
| 3 | FLGB | output | Active-low open-drain fault flag output for channel B, indicating current limit when ENB is active, and thermal shutdown or undervoltage in normal operation. |
| 4 | ENB | input | Enable input for MOSFET switch B, active low for the SP2526A-2 variant; enable input voltage range is -0.3V to 15V. |
| 5 | OUTB | passive | Output of the channel B MOSFET source, typically connected to the switched side of the load. |
| 6 | GND | power_in | Ground. |
| 7 | IN | power_in | Power supply input, +3.0V to +5.5V operating range with 7.0V absolute maximum, bypass with 0.1µF to 1µF to GND. |
| 8 | OUTA | passive | Output of the channel A MOSFET source, typically connected to the switched side of the load. |
