GC9111 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 goes high-impedance in sleep mode (IN1=IN2=0) and is disabled when VCC falls below 2 V or the junction exceeds 170 °C. |
| 2 | GND | power_in | Ground pin for the device; per the application notes, the motor return ground should be isolated from it in the PCB layout. |
| 3 | OUT1 | output | H-bridge output 1, which goes high-impedance in sleep mode (IN1=IN2=0) and is disabled when VCC falls below 2 V or the junction exceeds 170 °C. |
| 4 | VCC | power_in | Supply pin with a 2 V to 6 V operating range (absolute maximum -0.3 V to 7 V); the bypass capacitor, especially a ceramic one, should be placed as close to this pin as possible. |
| 5 | IN1 | input | PWM logic input 1 with an absolute range of -0.5 V to 7 V and an internal 100 kΩ pull-down that defaults it to low. |
| 6 | IN2 | input | PWM logic input 2 with an absolute range of -0.5 V to 7 V and an internal 100 kΩ pull-down that defaults it to low. |
