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). |
