LTC2913
Dual UV/OV
Voltage Monitor
FEATURES DESCRIPTION
n
Monitors Two Voltages Simultaneously
The LTC 2913 is a dual input voltage monitor intended for
n
Adjustable UV and OV Trip Values
multiple voltages in a variety of applications. Dual inputs for
n
Guaranteed Threshold Accuracy: 1.5%
each voltage allow monitoring two separate undervoltage
n
Input Glitch Rejection
(UV) conditions and two separate overvoltage (OV)
n
Adjustable Reset Timeout with Disable
conditions. All monitors share a common undervoltage
n
44A Quiescent Current
output and a common overvoltage output. The LTC2913-1
n
Open-Drain OV and UV Outputs
has latching capability for the overvoltage output. The
n
Guaranteed OV and UV for V 1V
LTC2913- 2 has functionality to disable both the overvoltage
CC
n
Available in 10-Lead MSOP and (3mm 3mm)
and undervoltage outputs.
DFN Packages
Glitch ltering ensures reliable reset operation without
false or noisy triggering.
APPLICATIONS
The LTC2913 provides a precise, versatile, space-con-
scious, micropower solution for voltage monitoring.
