Pin Functions

PIN I/O(1) DESCRIPTION EXTERNAL COMPONENTS
OR CONNECTIONS
NAME SOIC HTSSOP
POWER AND GROUND
GND 5, 6, 7,
14, 15, 16		 5, 12, PPAD — Device ground All pins must be connected to GND.
VM 1 1 — Device power supply Connect to motor supply (8.2 V to 60 V).
CONTROL
DIR 17 13 I Direction input Level controls direction of rotation – internal pulldown
nENBL 10 8 I Enable input Active low enables outputs – internal pulldown
RESET 11 9 I Reset input Active-high reset input initializes internal logic – internal pulldown
SM0 13 11 I Step mode Sets step mode – see step modes section for details – internal pulldowns
SM1 12 10
STEP 18 14 I Step input Rising edge advances motor to next step – internal pulldown
STATUS
nFAULT 20 16 OD Fault Logic low when in fault condition (overtemp, overcurrent)
nHOME 19 15 OD Home Logic low when indexer is at home position – push-pull structure
OUTPUT
OUT1 3 3 O Output 1 Connect to load 1
OUT2 4 4 O Output 2 Connect to load 2
OUT3 8 6 O Output 3 Connect to load 3
OUT4 9 7 O Output 4 Connect to load 4
VCLAMP 2 2 — Output clamp voltage Connect to VM supply, or Zener diode to VM supply
(1) Directions: I = input, O = output, OD = open-drain output
