L9110SM from HGSEMI, 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
1	OA	output	Channel A H-bridge output. Push-pull output that drives one terminal of the motor/load; continuous 800 mA, peak 1.5 A. Saturation drop ~1.0 V at 500 mA; goes high-Z when both IA and IB are low.
2	VCC	power_in	Positive supply input, 2.3 V to 12 V (abs max 15 V). Pins 2 and 3 are internally the VCC rail and should both be connected to the supply with decoupling.
3	VCC	power_in	Positive supply input, 2.3 V to 12 V (abs max 15 V). Shares the VCC net with pin 2; tie both to the supply rail.
4	OB	output	Channel B H-bridge output. Push-pull output that drives the other terminal of the motor/load; continuous 800 mA, peak 1.5 A. Goes high-Z when both IA and IB are low.
5	GND	power_in	Ground / 0 V reference. Pins 5 and 8 are the internal ground and both must be tied to system GND.
6	IA	input	Channel A control input. TTL/CMOS-compatible logic input (VIH ≥ 2.2 V, VIL ≤ 0.7 V, ~100 µA input current at VCC = 5 V). With IA = H and IB = L the motor turns forward.
7	IB	input	Channel B control input. TTL/CMOS-compatible logic input (VIH ≥ 2.2 V, VIL ≤ 0.7 V, ~100 µA input current at VCC = 5 V). With IA = L and IB = H the motor turns in reverse; both high brakes, both low coasts (high-Z).
8	GND	power_in	Ground / 0 V reference. Shares the GND net with pin 5; both should be tied to system ground.
