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

function independently. While the LTC2912 operates

directly from 2.3V to 6V supplies, an internal V

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

output; the LTC2912‑2

has an

and

output disable feature for margining

applications; the LTC2912‑3 is identical to the LTC2912‑1

but with a noninverting,

output.

The LTC2912 provides a precise, versatile, space‑conscious

micropower solution for voltage monitoring.
