GC9110T

SX-globalchip · Stepper Motor Driver · ESOP-8

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).
