GC8871

SX globalchip · Brushed DC Motor Drivers · ESOP-8

GC8871 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 GND power_in Ground pin of the device; the datasheet gives no further limit for this pin.
2 IN2 input Logic input 2 controls the H-bridge; VIL is 0.5 V maximum, VIH is 2.5 V minimum, and logic inputs are rated 0 to 5.5 V.
3 IN1 input Logic input 1 controls the H-bridge; VIL is 0.5 V maximum, VIH is 2.5 V minimum, and logic inputs are rated 0 to 5.5 V.
4 ILIM input Current-limit control pin, which requires a pulldown resistor to ground to set the peak drive current (3.6 A maximum).
5 VM power_in Motor supply pin with an operating range of 6.5 V to 45 V and an undervoltage lockout threshold of 6.1 to 6.4 V.
6 OUT1 output H-bridge output 1 driven by the internal four-NMOS bridge, with output current rated 0 to 3.6 A per channel.
7 PGND power_in H-bridge current ground return for the power stage.
8 OUT2 output H-bridge output 2 driven by the internal four-NMOS bridge, with output current rated 0 to 3.6 A per channel.
9 EP passive Exposed pad (from the footprint; not named in the datasheet pin table).
