L9110SSA.TR

Wuxi I-core Elec · Motor Driver ICs · SOP-8

L9110SSA.TR from Wuxi I-core Elec, 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 X4 output Forward-rotation motor output (X4); driven high for forward (BAK=0, FOR=1), low for reverse and brake, high-Z in standby.
2 VDD1 power_in Power supply for the H-bridge output stage; operating range 2 to 5.5 V (typ. 5 V), absolute maximum 7.0 V.
3 VDD2 power_in Logic supply; operating range 2 to 5.5 V (typ. 5 V), absolute maximum 7.0 V.
4 X3 output Reverse-rotation motor output (X3); driven high for reverse (BAK=1, FOR=0), low for forward and brake, high-Z in standby.
5 GND power_in Ground; must be shorted externally to pin 8.
6 FOR input Forward-rotation logic input; VIH min 2.2 V and VIL max 0.8 V at VDD2=4.5 V.
7 BAK input Reverse-rotation logic input; VIH min 2.2 V and VIL max 0.8 V at VDD2=4.5 V.
8 GND power_in Ground; must be shorted externally to pin 5.
