The LTC^®2908 is a six supply monitor for systems with a large number of supply voltages that require a precise and compact solution. 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 (40°C to 85°C) 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 two 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.
