GC9118S from SX globalchip, in a SOT23-6. 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 | OUT2 | output | H-bridge output 2, which is driven low when IN1=1/IN2=0 (forward), high when IN1=0/IN2=1 (reverse), and high-impedance in sleep (IN1=IN2=0); the device rating is 1.1 A continuous and 2.2 A peak output current. |
| 2 | GND | power_in | Ground pin; per the layout guidance, the motor return ground should be isolated from the logic ground. |
| 3 | IN2 | input | Logic input 2 for the IN/IN PWM control, with a 100 kΩ internal pull-down so it defaults low; at VCC=5 V the logic-low limit is 1.0 V max and the logic-high threshold is 2.1 V min, and the absolute input range is -0.5 to 7 V. |
| 4 | IN1 | input | Logic input 1 for the IN/IN PWM control, with a 100 kΩ internal pull-down so it defaults low; at VCC=5 V the logic-low limit is 1.0 V max and the logic-high threshold is 2.1 V min, and the absolute input range is -0.5 to 7 V. |
| 5 | VCC | power_in | Supply pin with a 2 to 6 V operating range (absolute maximum -0.3 to 7 V); below 2 V the H-bridge outputs are turned off by undervoltage lockout and re-enable when the supply rises to 2.2 V. |
| 6 | OUT1 | output | H-bridge output 1, which is driven high when IN1=1/IN2=0 (forward), low when IN1=0/IN2=1 (reverse), and high-impedance in sleep (IN1=IN2=0); the device rating is 1.1 A continuous and 2.2 A peak output current. |
