Power Supply Protection
The device contains an on-chip regulator and can operate over
a wide V
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 specifi cations. Refer to fi gure 7 for an example of a basic
application circuit.
