LTC2913

Dual UV/OV

Voltage Monitor

DESCRIPTION

The LTC®2913 is a dual input voltage monitor intended for

multiple voltages in a variety of applications. Dual inputs for

each voltage allow monitoring two separate undervoltage

(UV) conditions and two separate overvoltage (OV)

conditions. All monitors share a common undervoltage

output and a common overvoltage output. The LTC2913-1

has latching capability for the overvoltage output. The

LTC2913-2 has functionality to disable both the overvoltage

and undervoltage outputs.

Glitch filtering ensures reliable reset operation without

false or noisy triggering.

The LTC2913 provides a precise, versatile, space-con-

scious, micropower solution for voltage monitoring.
