The LTC2908 is a six input supply monitor for systems requiring a precise and compact monitoring solution for multiple supply voltages. The inputs can be shorted together for monitoring systems with fewer than six supply voltages, and the open drain RST output of two or more LTC2908s can be wired-OR together for monitoring systems with more than six supply voltages. The common reset output remains low until all six inputs have been in compliance for 200ms.
The LTC2908 features a tight 1.5% threshold accuracy over the entire operating temperature range and glitch immunity to ensure reliable reset operation without false triggering. The open-drain RST output state is guaranteed to be in the correct state as long as V1 and/or V2 is 0.5V or greater.
The LTC2908 also features adjustable inputs with a nominal threshold level at 0.5V. This product provides a precise, space-conscious, micropower and general purpose solution for any kind of system requiring supply monitors.
