1 / 12 page  LTC2913 1 2913fb FEATURES APPLICATIONS 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 filtering ensures reliable reset operation without false or noisy triggering. The LTC2913 provides a precise, versatile, space-con- scious, micropower solution for voltage monitoring. n Monitors Two Voltages Simultaneously n Adjustable UV and OV Trip Values n Guaranteed Threshold Accuracy: ±1.5% n Input Glitch Rejection n Adjustable Reset Timeout with Disable n 44μA Quiescent Current n Open-Drain OV and UV Outputs n Guaranteed OV and UV for VCC ≥ 1V n Available in 10-Lead MSOP and (3mm × 3mm) DFN Packages n Desktop and Notebook Computers n Network Servers n Core, I/O Voltage Monitors Dual OV/UV Supply Monitor Typical Transient Duration vs Comparator Overdrive TYPICAL APPLICATION L, LT, LTC and LTM are registered trademarks of Linear Technology Corporation.
