Analog Devices Inc. expanded its portfolio of multi-voltage supervisory
ICs with new circuits for monitoring negative-voltage and over- and
under-voltage conditions. The ADM2914 and the ADM12914 quad-channel
voltage supervisors and ADM6339 microprocessor supervisor ICs enhance
overall system reliability by helping ensure voltage levels remain
within specified levels.
The ADM12914 detects over-voltage and under-voltage (OV/UV)
conditions with an accuracy of +/-0.8 percent over
temperature. The ADM2914/ADM12914 also includes an input-supply shunt
regulator that enables the device to be run off of higher-voltage
supplies, including 12-V operation in communications infrastructure
equipment and lithium-ion batteries used in hybrid vehicles.
The ADM6339 quad microprocessor voltage supervisory circuit provides
an accuracy of +/-0.8 percent over temperature and monitors up
to three positive and one negative voltage supplies. The ADM6339
incorporates internally pre-trimmed under-voltage threshold options for
monitoring 1.8-V, 2.5-V, 3-V, 3.3-V, 5-V, and -5-V supply voltages and
is available with one to three adjustable threshold options to extend
ADM12914 and ADM6339 supervisory circuits are compatible with ADI's
point-of-load regulators, including the ADP1740, ADP1741 and ADP2102,
ADP2105, ADP2106, ADP2107, ADP2108, family.
