Power Supply Protection
The device contains an on-chip regulator and can operate over a
wide V
lated power supply, transient protection must be added externally.
For applications using a regulated line, EMI/RFI protection may
still be required. Contact Allegro for information on the circuitry
needed for compliance with various EMC specifications. Refer to
figure 7 for an example of a basic application circuit.
Undervoltage Lockout
When the supply voltage falls below the undervoltage lockout
threshold, V
output state returns to the Power-On State (POS) until sufficient

Diagnostics
The regulated current output is configured for two-wire applica-
tions, requiring one less wire for operation than do switches with
the traditional open-collector output. Additionally, the system
designer inherently gains diagnostics because there is always
output current flowing, which should be in either of two nar-
row ranges, shown in figure 8 as I
current level not within these ranges indicates a fault condition.
