DESCRIPTION
Dual UV/OV
Voltage Monitor
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 fi ltering ensures reliable reset operation without
false or noisy triggering.
The LTC2913 provides a precise, versatile, space-con-
scious, micropower solution for voltage monitoring.

ELECTRICAL CHARACTERISTICS
Note 1: Stresses beyond those listed under Absolute Maximum Ratings
may cause permanent damage to the device. Exposure to any Absolute
Maximum Rating condition for extended periods may affect device
reliability and lifetime.
Note 2: All currents into pins are positive; all voltages are referenced to
GND unless otherwise noted.

Note 3: V
CC
maximum pin voltage is limited by input current. Since the
V
CC
pin has an internal 6.5V shunt regulator, a low impedance supply that
exceeds 6V may exceed the rated terminal current. Operation from higher
voltage supplies requires a series dropping resistor. See Applications
Information.
