MS35776

杭州瑞盟 · Stepper Motor Driver · QFN-28-EP(5x5)

MS35776 from 杭州瑞盟, in a QFN-28-EP(5x5). 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 BOUT2 output Motor coil B output 2 of the full-bridge driver.
2 ENN input Enable input; when high it disables the output drivers, and per the datasheet ENN low enables the output drive and ENN is used to reset FAULT.
3 GND power_in Ground.
4 CPO passive Charge-pump capacitor output, connected to CPI through a 22nF/50V capacitor.
5 CPI passive Charge-pump capacitor input, connected to CPO through a 22nF/50V capacitor.
6 VCP power_out Charge-pump voltage, connected to VM through a 100nF capacitor.
7 MODE input Operating mode select with internal pull-up: 1 selects quiet mode and 0 selects fast mode.
8 V5 power_out Internal 5V LDO output, requiring a 2.2µF to 4.7µF capacitor to ground; all outputs are turned off if V5 falls low.
9 MS1 input Microstep configuration input with internal pull-down resistor.
10 MS2 input Microstep configuration input with internal pull-down resistor.
11 FAULT output Internal error signal output that goes high when the driver outputs are shut off; it can be reset via ENN.
12 FG0 output Outputs a pulse on positive zero-crossing of the A-coil current.
13 CLK input Clock input; can be tied to ground when the internal clock is used.
14 PDN bidirectional Automatic current decay mode input; pulling it low enables automatic current decay at standstill.
15 VIO power_in Supply for the digital I/O pins, 3.3V to 5V.
16 STEP input Microstep step input.
17 VREF power_in Analog reference voltage input controlling the output current; in internal sense-resistor mode it serves as the analog reference current input.
18 GND power_in Ground.
19 DIR input Direction input with internal pull-down resistor.
20 NC unconnected Not used; the datasheet recommends connecting this pin to ground.
21 AOUT2 output Motor coil A output 2 of the full-bridge driver.
22 VM power_in Motor supply voltage.
23 SENA bidirectional Source terminal of the coil A low-side MOSFET; connect the sense resistor to ground, or connect directly to ground in internal sense-resistor mode.
24 AOUT1 output Motor coil A output 1 of the full-bridge driver.
25 GND power_in Ground.
26 BOUT1 output Motor coil B output 1 of the full-bridge driver.
27 SENB bidirectional Source terminal of the coil B low-side MOSFET; connect the sense resistor to ground, or connect directly to ground in internal sense-resistor mode.
28 VM power_in Motor supply voltage.
29 EPAD passive Exposed pad (from the footprint; not named in the datasheet pin table).
