GC8123 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 | OUTB | output | H-bridge output B, which drives high, low, or high-impedance according to the INA/INB truth table (INA=0, INB=1 gives OUTB high; INA=INB=0 gives high-impedance sleep state); continuous drive current is rated at 1.2 A and peak at 2.0 A for the device. |
| 2 | GND | power_in | Ground reference; the datasheet recommends isolating the motor return ground from logic ground in the PCB layout. |
| 3 | INA | input | Logic input A for PWM (IN/IN) control, with an internal 100 kΩ pull-down that defaults it low; control input range is -0.5 to 7 V, and VIH is 2.1 V minimum at VCC=5 V. |
| 4 | OUTA | output | H-bridge output A, which drives high, low, or high-impedance according to the INA/INB truth table (INA=1, INB=0 gives OUTA high; INA=INB=0 gives high-impedance sleep state); continuous drive current is rated at 1.2 A and peak at 2.0 A for the device. |
| 5 | VCC | power_in | Logic and motor supply input, operating from 1.2 to 6 V (absolute maximum -0.3 to 7 V), with the bypass capacitor placed as close to this pin as possible. |
| 6 | INB | input | Logic input B for PWM (IN/IN) control, with an internal 100 kΩ pull-down that defaults it low; control input range is -0.5 to 7 V, and VIH is 2.1 V minimum at VCC=5 V. |
