Power Supply Protection
The device contains an on-chip regulator and can operate over
a wide V
CC
range. For devices that need to operate from an
unregulated power supply, transient protection must be added
externally. For applications using a regulated line, EMI/RFI pro-
tection may still be required. Contact Allegro Microsystems for
information on the circuitry needed for compliance with various
EMC speci
fi
cations. Refer to
fi
gure 7 for an example of a basic
application circuit.
Undervoltage Lockout
When the supply voltage falls below the undervoltage lockout
voltage, V
CC(UV)
, the device enters Reset, where the output state
returns to the Power-On State (POS) until suf
fi
cient V
CC
is sup-
plied. I
CC
levels may not meet datasheet limits when
V
CC
< V
CC(min)
.
Assembly Description
This sensor is integrally molded into a plastic body that has been
optimized for size, ease of assembly, and manufacturability.
High operating temperature materials are used in all aspects
of construction.
