GR2823M

GR · Stepper Motor Driver · SOP-16

GR2823M from GR, in a SOP-16. 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 VDDL power_in Low-voltage logic supply, 3V to 5.5V.
2 GND power_in Power ground.
3 SCK input Serial data clock input, maximum SCK frequency 10 MHz.
4 EN input Output enable input, driven high after the 8-bit shift to latch data to the outputs.
5 RST input Output reset input, high closes all outputs and low enables them.
6 DATA input Serial data input.
7 GND power_in Power ground.
8 VDDH power_in High-voltage motor/load supply, 3V to 18V.
9 M2D output Open-drain output, group 2 phase D, up to 400 mA with built-in clamp diode.
10 M2C output Open-drain output, group 2 phase C, up to 400 mA with built-in clamp diode.
11 M2B output Open-drain output, group 2 phase B, up to 400 mA with built-in clamp diode.
12 M2A output Open-drain output, group 2 phase A, up to 400 mA with built-in clamp diode.
13 M1D output Open-drain output, group 1 phase D, up to 400 mA with built-in clamp diode.
14 M1C output Open-drain output, group 1 phase C, up to 400 mA with built-in clamp diode.
15 M1B output Open-drain output, group 1 phase B, up to 400 mA with built-in clamp diode.
16 M1A output Open-drain output, group 1 phase A, up to 400 mA with built-in clamp diode.
