Features I2C Interface, Peak Value Tracking and Runs from
Any Supply
CY Lai Power monitoring in combination with control mechanisms can significantly boost
system energy efficiency and reliability. The LTC2945 is a highly integrated digital
power monitoring solution that is compact, rugged and easy-to-use. It is designed to
fit applications requiring power monitoring with a minimal number of components.
MONITOR POWER ON ANY SUPPLY The secondary supply exists, but is not
readily accessibleвЂ”it is inconveniently
located on the printed circuit board,
complicating the routing of a power line The LTC2945вЂ™s internal current sense
amplifier features a common mode range
of 0V to 80V to suit a wide variety of high
side and low side current sensing applications. Most wide range supply monitors
available today require a low voltage
secondary supply for operation, which
can be undesirable for several reasons: The LTC2945 avoids these problems by
integrating a high voltage linear regulator
that can be powered directly from 4V to
80V supplies. The output of the linear regulator (INTVCC) powers the LTC2945, and can
be externally bypassed to prevent supply
noise from corrupting the signal integrity
of internal circuitry. The linear regulator is …
