L9110S-MS

MSKSEMI · Stepper Motor Driver · SOP-8

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.
