LTC2912

Single UV/OV

Voltage Monitor

FEATURES

DESCRIPTION

TheLTC^®2912voltagemonitorisdesignedtodetectpower

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

Monitors Single Voltage

Adjustable UV and OV Trip Values

Guaranteed Threshold Accuracy: ±±1.5

Power Supply Glitch Immunity

Adjustable Reset Timeout with Timeout Disable

29µA Quiescent Current

Open‑Drain OV and UV Outputs

Guaranteed OV and UV for V ≥ 1V

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

Available in 8‑Lead ThinSOT^TMand (3mm × 2mm)

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.

APPLICATIONS

Desktop and Notebook Computers

Network Servers
