DESIGN FEATURES L Dual/Triple Power Supply Monitor for
Undervoltage and Overvoltage on
Positive and Negative Supplies
by Andrew Thomas Introduction
An accurate power supply monitor
can signal when a supply overvoltage
or undervoltage condition threatens
to cause system failures, allowing
the system to deal with the situation
gracefully.
The LTC2909 is a highly customizable monitoring solution with
adjustable input thresholds, input
polarity selection, a multimode reset
timer, and an open-drain RST output.
Adjustable input thresholds allow the
user to set any trip threshold for the
comparator, subject only to the accuracy limitations of the part, instead
of having to pick from a factory-set
limited collection of thresholds.
Each adjustable input can be
conп¬Ѓgured in either polarity, allowing it to monitor negative or positive
supply voltages for undervoltage or
overvoltage. Polarity selection is controlled by simple connection of the …
