Sensed current copper conduction path pins. Terminals for current being sensed;
fused internally, loop to IP– pins; unidirectional or bidirectional current flow.
Sensed current copper conduction path pins. Terminals for current being sensed;
fused internally, loop to IP+ pins; unidirectional or bidirectional current flow.
Device ground connection.
Voltage Reference Output pin. Zero current (0 A) reference; output voltage on this
pin scales with V
Filter pin. Terminal for an external capacitor connected from this pin to GND to set
the device bandwidth.
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.
Supply voltage.
Overcurrent Input pin. Analog input voltage on this pin sets the overcurrent fault
threshold.
