Voltage Reference Output pin. Zero current (0 A)
reference; output voltage on this pin scales with VCC
(Not a highly accurate reference.)

Filter pin. Terminal for an external capacitor connected
from this pin to GND to set the device bandwidth.

FILTER
VIOUT
Analog Output pin. Output voltage on this pin is
proportional to current flowing through the loop
between the IP+ pins and IP– pins.
Overcurrent Fault pin. When current flowing
between IP+ pins and IP– pins exceeds the
overcurrent fault threshold, this pin transitions to a
logic low state.
