Exposed PAD
Analog Gnd
Exposed PAD; metal plate on the IC bottom side connected to
analog ground.
A high quality ground plane (about 500 mil inch over 500 mil inch)
should be deployed around this pin whenever possible.
1
CURRENT_SET
Digital Input
User input to set AF / AT and maximum current limit.
Use Pull-up resistors to DVDD or Pull-Down resistors to DGND to set
mode of operation according to the detailed tables (page 4).

AF/AT
Digital Input
3
DVDD
Power In
Regulated Input Voltage (3.3 V) for internal digital circuitry.
Should be externally connected to pin 4.
4
VAUX3P3
Power In
Voltage regulation in 3.3 VDC.
To be connected to pin 5.
A 4.7 uF capacitor to AGND is recommended.
5
DRV_VAUX3P3
Power Out
Internal voltage regulator out 3.3 VDC.
To be connected externally to pin 4.
6
VAUX5
Power
Regulated 5 VDC voltage filter.
A 1 uF capacitor to AGND is recommended.
7
AGND
Power
Analog GND
8
V_MAIN
Power
Supply voltage for the internal analog circuit. Place a low ESR
bypass capacitor, not less than 1 uF, as close as possible to AGND
and this pin with low impedance traces.
9
PORT_NEG
Analog I/O
Negative output of the port.
10
PORT_SENSE
Analog Input
Sense resistor port input (connected to 0.5, 1% Ohm resistor to
GND).
11
QGND
Power
Quiet analog ground: used for sensitive analog cells.
12
I_REF
Analog I/O
Resistor reference. Connect 30.1 K 1% resistor to QGND.
13
LED0
Open Drain
I/O
Port Status Direct LED indications – see detailed table description.
This is a High voltage, Open drain, Active low (SINK) output pin.
Recommended to be connected to LED and Vmain through a
~18.2 Kohm (~3 mA) resistor

17
TRIM
Analog Input
Zapping Input for IC production trimming.
Should be connected to DVDD.
18
SYNC
Digital I/O
Synchronization open drain IO pin between master and slave, for 4-
Pair applications
In ALT A 2 Pair mode (Switch) this pin should be pulled down to
DGND via a 4.7 Kohm resistor.
In 4 Pair mode, connect the SYNC pin of Master and Slave and pull it
up to the DVDD with 4.7 Kohm resistor
19
DGND
Digital I/O
Digital GND.
20
RESET_N
Digital Input
Reset input / On-Off command (Active Low).
21
MODE 0
Test I/O
Configuration Input Pins: Used to set Mode of operation and Test
mode at production.
Typically connected to DGND.
See Table Below
