LTC Intros LTC2908 Six Supply Monitor

Linear Technology Corp. (LTC, Milpitas, CA) introduced the LTC2908, a six supply monitor for densely packed systems with large numbers of supplies. Housed in small SOT-23 and DFN packages, the hex supply supervisor accommodates the latest generation of systems, with multiple, low-voltage supply rails in addition to the traditional 5 V or 3.3 V logic supplies. The LTC2908 is suitable for multi-voltage, high-density systems such as desktop and notebook computers, optical networking systems, and wireless base stations.

The LTC2908 features two adjustable inputs with a nominal threshold of 0.5 V and four fitted thresholds. The LTC2908-A1 gives a choice of monitoring 5 V, 3.3 V, 2.5 V, 1.8 V, ADJ1 and ADJ2 voltages, while the LTC2908-B1 monitors accommodates the 3.3 V, 2.5 V, 1.8 V, 1.5 V, ADJ1 and ADJ2 voltages. The tight 1.5-percent threshold accuracy over the entire operating temperature range of -40 °C to +85 °C provides an extra degree of precision.

The LTC2908 is offered in eight-pin, SOT-23 and 2 mm x 3 mm DFN packages. The IC is specified over the commercial and industrial temperature ranges, and pricing begins at $2.50 each for 1,000-piece quantities.
