Pinout

Pin Name Type Function
1 VM power_in Power supply input; connect to motor supply voltage and bypass to PGND with a 0.01-μF ceramic capacitor on each VM pin plus a bulk capacitor rated for VM.
2 PGND power_in Power ground; connect to system ground.
3 OUT1 output Winding output; connect to motor winding.
4 OUT2 output Winding output; connect to motor winding.
5 OUT2 output Winding output; connect to motor winding.
6 OUT1 output Winding output; connect to motor winding.
7 PGND power_in Power ground; connect to system ground.
8 VM power_in Power supply input; connect to motor supply voltage and bypass to PGND with a 0.01-μF ceramic capacitor on each VM pin plus a bulk capacitor rated for VM.
9 GND power_in Device ground; connect to system ground.
10 DVDD power_out Logic supply voltage; connect a X7R 0.47-μF to 1-μF, 6.3-V or 10-V rated ceramic capacitor to GND.
11 nFAULT output Fault indication, pulled logic low with a fault condition; open-drain output requires an external pullup resistor.
12 VREF power_in Reference voltage input that sets the full-scale chopping current in the H-bridge; must be tied together with the other VREF pin.
13 VREF power_in Reference voltage input that sets the full-scale chopping current in the H-bridge; must be tied together with the other VREF pin.
14 TOFF input Quad-level pin that sets the decay mode off-time during current chopping and the ripple current in smart tune ripple control mode.
15 NC unconnected No connect.
16 DECAY input Decay mode setting pin; quad-level pin.
17 NC unconnected No connect.
18 NC unconnected No connect.
19 PH input Phase input; logic high drives current from OUT1 to OUT2.
20 EN input Enable input; logic high enables the bridge, logic low disables the bridge Hi-Z.
21 nSLEEP input Sleep mode input; logic high enables the device, logic low enters low-power sleep mode, with internal pulldown resistor.
22 CPL passive Charge pump switching node; connect a X7R 0.022-μF VM-rated ceramic capacitor from CPH to CPL.
23 CPH passive Charge pump switching node; connect a X7R 0.022-μF VM-rated ceramic capacitor from CPH to CPL.
24 VCP power_out Charge pump output; connect a X7R 0.22-μF 16-V ceramic capacitor to VM.
25 EP passive Exposed pad (from the footprint; not named in the datasheet pin table).
