LTC2912
Single UV/OV
Voltage Monitor
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
function independently. While the LTC2912 operates
directly from 2.3V to 6V supplies, an internal VCC 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.
