Pin Functions

PIN TYPE DESCRIPTION
NAME PWP RHR
CPL 1 27 PWR Charge pump switching pins Connect a VM rated, 0.1-µF ceramic capacitor between CPH and CPL
CPH 2 28
VCP 3 1 O Charge pump output Connect a 16 V, 0.47 µF ceramic capacitor to VM
VM 4, 11 2, 9 PWR Power supply Connect to motor supply voltage; bypass to GND with two 0.1 µF (for each pin) plus one bulk capacitor rated for VM
AOUT1 5 3 O Winding A output H-bridge outputs, drives one winding of a stepper motor
AOUT2 7 5
AISEN 6 4 O Winding A sense Requires sense resistor to GND; value sets peak current in winding A
BOUT2 8 6 O Winding B output H-bridge outputs, drives one winding of a stepper motor
BOUT1 10 8
BISEN 9 7 O Winding B sense Requires sense resistor to GND; value sets peak current in winding B
GND 12, 28 10, 26 PWR Device ground Must be connected to ground
ATE 13 11 I Smart tune enable pin Logic high enables smart tune operation; when logic low, the decay mode is set through the DECAYx pins; smart tune must be pulled high prior to power-up or coming out of sleep, or else tied to V3P3 in order to enable smart tune; internal pulldown; see Smart Tune
VREF 14 12 I Full scale current reference input Voltage on this pin sets the full scale chopping current.
V3P3 15 13 PWR Internal regulator Internal supply voltage; bypass to GND with a 6.3 V, 0.47 µF ceramic capacitor; up to 10 mA external load
TOFF 16 14 I Decay mode off time set Sets the off-time during current chopping; tri-level pin
nSLEEP 17 15 I Sleep mode input Logic high to enable device; logic low to enter low-power sleep mode; internal pulldown
nFAULT 18 16 O Fault indication pin Pulled logic low with fault condition; open-drain output requires an external pullup
DECAY1 19 17 I Decay mode setting pins Sets the decay mode; see description section; tri-level pin
DECAY0 20 18
ENABLE 21 19 I Enable driver input Logic high to enable device outputs and internal indexer; logic low to disable; internal pulldown
DIR 22 20 I Direction input Logic level sets the direction of stepping; internal pulldown
STEP 23 21 I Step input A rising edge causes the indexer to advance one step; internal pulldown
M1 24 22 I Microstepping mode setting pins Sets the step mode; full, 1/2, 1/4, 1/8, 1/16; tri-level pin
M0 25 23
TRQ1 26 24 I Torque DAC current scalar Scales the current by 100%, 75%, 50%, or 25%; internal pulldown
TRQ0 27 25
PAD PAD PAD PWR Thermal pad Must be connected to ground
