GC9110T 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, driving the motor with up to 1.5A continuous (2.5A peak) output current. |
| 2 | VM | power_in | Motor power supply, 3.8V to 12V operating range (17V absolute maximum), to be bypassed with a capacitor placed as close to the pin as possible. |
| 3 | VM | power_in | Motor power supply, 3.8V to 12V operating range (17V absolute maximum), internally the same supply as pin 2 and bypassed close to the pin. |
| 4 | OUT2 | output | H-bridge output 2, driving the motor with up to 1.5A continuous (2.5A peak) output current. |
| 5 | GND | power_in | Ground. |
| 6 | IN1 | input | Logic input 1 for PWM (IN/IN) control, compatible with 3.3V and 5V logic, with internal ~100kΩ pull-down; IN1=IN2=0 enters sleep mode. |
| 7 | IN2 | input | Logic input 2 for PWM (IN/IN) control, compatible with 3.3V and 5V logic, with internal ~100kΩ pull-down; IN1=IN2=0 enters sleep mode. |
| 8 | GND | power_in | Ground. |
| 9 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
