SSP8023D from Shanghai Siproin Microelectronics, in a SOP-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
5	VDD	power_in	Supply input voltage. Recommended safe working voltage 5~24V; limit operating voltage 30V; max input voltage 40V (absolute).
2	GND	power_in	Ground reference for the device.
3	INA	input	Input A. Pulse-triggered control input for output driver A. Input threshold ~1.5V (typ), 2V (max); equivalent input resistance ~120kΩ. Recommended pulse width 100ms with >100ms spacing.
4	OUTA	output	Output A. Push-pull bi-directional driver output to relay/motor coil. RDS(on) typ 6~7Ω; limit current 800mA; high-impedance when INA=INB. Integrated freewheeling diode.
6	INB	input	Input B. Pulse-triggered control input for output driver B. Input threshold ~1.5V (typ), 2V (max); equivalent input resistance ~120kΩ. Recommended pulse width 100ms with >100ms spacing.
1	OUTB	output	Output B. Push-pull bi-directional driver output to relay/motor coil. RDS(on) typ 6~7Ω; limit current 800mA; high-impedance when INA=INB. Integrated freewheeling diode.
