**SX globalchip** · Gate Drivers · ESOP-8

GC9110 from SX globalchip, in a ESOP-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 | OUT1 | output | H-bridge output 1, which goes high-impedance (Z) in standby when IN1=IN2=0 and is rated for 1.3 A continuous output current (2.3 A peak). |
| 2 | VCC | power_in | Supply pin for the logic and H-bridge, specified at 2 V to 6 V; the bridge disables below 2 V and re-enables at 2.2 V, and the VCC bypass capacitor should be placed as close to this pin as possible. |
| 3 | VCC | power_in | Second supply pin, connected to the same 2 V to 6 V VCC supply as pin 2. |
| 4 | OUT2 | output | H-bridge output 2, which goes high-impedance (Z) in sleep when IN1=IN2=0 and is rated for 1.3 A continuous output current (2.3 A peak). |
| 5 | GND | power_in | Ground pin, which should be routed separately from the motor return current in the PCB layout. |
| 6 | IN1 | input | Logic input 1 of the PWM IN1/IN2 interface, with a 100 kΩ internal pull-down (defaults low), VIH minimum 2.1 V and VIL maximum 1.0 V at VCC=5 V, and a control input absolute maximum of 7 V. |
| 7 | IN2 | input | Logic input 2 of the PWM IN1/IN2 interface, with a 100 kΩ internal pull-down (defaults low), VIH minimum 2.1 V and VIL maximum 1.0 V at VCC=5 V, and a control input absolute maximum of 7 V. |
| 8 | GND | power_in | Second ground pin, connected to the same ground as pin 5. |
| 9 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
