SP2526A-1EN-L from MaxLinear, in a SOIC-8. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin	Name	Type	Function
1	ENA	input	Enable input for channel A. Active-high on the SP2526A-1 variant (this part). Logic-high threshold 2.0V min; logic-low threshold 0.8V min. Absolute max -0.3V to 15V.
2	FLGA	output	Active-low, open-drain fault flag output for channel A. Asserts low on channel-A current limit, thermal shutdown, or undervoltage (when ENA/ENB active). Output resistance ~10Ω at VIN=5V, IL=10mA. Requires external pull-up.
3	FLGB	output	Active-low, open-drain fault flag output for channel B. Asserts low on channel-B current limit, thermal shutdown, or undervoltage (when ENA/ENB active). Output resistance ~10Ω at VIN=5V, IL=10mA. Requires external pull-up.
4	ENB	input	Enable input for channel B. Active-high on the SP2526A-1 variant (this part). Logic-high threshold 2.0V min; logic-low threshold 0.8V min. Absolute max -0.3V to 15V.
5	OUTB	power_out	Switched power output for channel B (source of the internal N-MOSFET). Connect to the switched USB VBUS load; supplies 500mA min per channel. Current-limited to ~1.0A typical.
6	GND	power_in	Device ground reference.
7	IN	power_in	Power supply input, +3.0V to +5.5V operating range (7.0V absolute max). Common drain for both channel switches. A 0.1µF to 1µF bypass capacitor to GND near the device is strongly recommended.
8	OUTA	power_out	Switched power output for channel A (source of the internal N-MOSFET). Connect to the switched USB VBUS load; supplies 500mA min per channel. Current-limited to ~1.0A typical.
