L9110S-MS from MSKSEMI, 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 | OUTA | output | H-bridge output A, which sources current to the motor in forward mode and goes high-impedance in standby; the recommended continuous output current is 0 to 1.2 A. |
| 2 | VM | power_in | Motor supply input with a recommended range of 2.5 to 12.0 V and an absolute maximum of 13.2 V; a 10 uF or larger capacitor must be connected between VM and ground. |
| 3 | VM | power_in | Motor supply input, internally the same supply as pin 2, with a recommended range of 2.5 to 12.0 V and an absolute maximum of 13.2 V; a 10 uF or larger capacitor must be connected between VM and ground. |
| 4 | OUTB | output | H-bridge output B, which sources current to the motor in reverse mode and goes high-impedance in standby; the recommended continuous output current is 0 to 1.2 A. |
| 5 | GND | power_in | Power ground for the H-bridge output stage, to be connected to the system ground. |
| 6 | INA | input | Logic input A controlling OUTA, with a recommended range of 0 to 7.0 V, VIH minimum 2.0 V and VIL maximum 0.8 V. |
| 7 | INB | input | Logic input B controlling OUTB, with a recommended range of 0 to 7.0 V, VIH minimum 2.0 V and VIL maximum 0.8 V. |
| 8 | GND | power_in | Power ground for the H-bridge output stage, to be connected to the system ground. |
