LTC2912
Single UV/OV
Voltage Monitor
FEATURES
DESCRIPTION
The LTC
®
2912 voltage monitor is designed to detect power
supply undervoltage and overvoltage events. The VL and
VH monitor inputs include filtering to reject brief glitches,
thereby ensuring reliable reset operation without false or
noisy triggering. An adjustable timer defines the duration of
the overvoltage and undervoltage reset outputs which func-
tion independently. While the LTC2912 operates directly
from 2.3V to 6V supplies, an internal V
CC
shunt regulator
coupled with low supply current demand allows operation
from higher voltages such as 12V, 24V or 48V.
Three output configurations are available: the LTC2912-
1 has a latch control for the
OV
output; the LTC2912-2
has an
OV
and
UV
output disable feature for margining
applications; the LTC2912-3 is identical to the LTC2912-1
but with a noninverting,
OV
output.
The LTC2912 provides a precise, versatile, space-conscious
micropower solution for voltage monitoring.
