Pin Functions
PIN
I/O DESCRIPTION
NAME NO.
ADEC 19 I AutoTune enable
Logic low sets decay modes by DEC0 and DEC1 pins; logic high –
AutoTune operation is enabled; must be set prior to coming out of
sleep; internal pulldown
AISEN 2 O Winding A sense
Connect to current sense resistor for bridge A, or GND if current
regulation is not required
AOUT1 1
O Winding A output
AOUT2 3
BISEN 5 O Winding B sense
Connect to current sense resistor for bridge B, or GND if current
regulation is not required
BOUT1 6
O Winding B output
BOUT2 4
DEC0 22 I
Decay mode setting pins Sets the decay mode; see description section; tri-level pin
DEC1 24 I
DIR 13 I Direction input Logic level sets the direction of stepping; internal pulldown
GND 18, PPAD PWR Device ground
Both the GND pin and device thermal pad must be connected to
ground
I0 20 I
Torque DAC current scalar Scales the current from 100% to 12.5% in 12.5% steps; tri-level pin
I1 21 I
MO 8 I
Microstepping mode setting
pins
Controls step mode (full, half, up to 1/32-step) and single- or dual-
edge clocking; tri-level pin
M1 9 I
NC 16 — No connect Unused pin not connected internally
nENBL 11 I Enable driver output
Logic low to enable device outputs and internal indexer; logic high to
disable; internal pulldown
nFAULT 7 OD Fault indication pin
Pulled logic low with fault condition; open-drain output requires
external pullup
nSLEEP 23 I Sleep mode input
Logic high to enable device; logic low to enter low-power sleep mode;
internal pulldown
STEP 12 I Step input
A rising edge (or rising and falling depending on step mode) advances
the indexer one step; internal pulldown
TOFF_SEL 10 I Decay mode off time set Sets the off-time during current chopping; tri-level pin
