Quad UV/OV monitor for pos and neg supplies
23 August 2006
Circuit & System Protection
Linear Technology's LTC2914 is a precision quad input voltage monitor with four separate undervoltage (UV) and overvoltage (OV) inputs, designed for systems with multiple supplies. This IC for voltage monitoring has the flexibility to configure specific UV and OV trip thresholds. It guarantees ±1,5% threshold accuracy over temperature. A buffered reference output and a three-state input polarity-select pin allows for monitoring of up to two separate negative voltages without the need of any external components. All monitors share open-drain outputs that can be wired-OR'd together to indicate a single fault. The LTC2914-1 has latching capabilities and features input glitch noise filters. The LTC2914 comes in 16-pin SSOP and 16-pin 5 mm x 3 mm DFN packages. A dual version, the LTC2913 in 10-pin MSOP and DFN packages is also available.
