Pin Functions

PIN I/O(1) DESCRIPTION EXTERNAL COMPONENTS
OR CONNECTIONS
NAME WQFN HTSSOP,
TSSOP
POWER AND GROUND
GND 11
PPAD		 13 — Device ground. HTSSOP package has PowerPAD. Both the GND pin and device PowerPAD must be connected to ground.
VINT 12 14 — Internal supply bypass Bypass to GND with 2.2-μF, 6.3-V capacitor.
VM 10 12 — Device power supply Connect to motor supply. A 10-µF (minimum) ceramic bypass capacitor to GND is recommended.
VCP 9 11 IO High-side gate drive voltage Connect a 0.01-μF, 16-V (minimum) X7R ceramic capacitor to VM.
CONTROL
AIN1 14 16 I Bridge A input 1 Logic input controls state of AOUT1. Internal pulldown.
AIN2 13 15 I Bridge A input 2 Logic input controls state of AOUT2. Internal pulldown.
BIN1 7 9 I Bridge B input 1 Logic input controls state of BOUT1. Internal pulldown.
BIN2 8 10 I Bridge B input 2 Logic input controls state of BOUT2. Internal pulldown.
nSLEEP 15 1 I Sleep mode input Logic high to enable device, logic low to enter low-power sleep mode and reset all internal logic. Internal pulldown.
STATUS
nFAULT 6 8 OD Fault output Logic low when in fault condition (overtemperature, overcurrent)
OUTPUT
AISEN 1 3 IO Bridge A ground / ISENSE Connect to current sense resistor for bridge A, or GND if current control not needed
