Six Supply Monitor

FEATURES

DESCRIPTIO

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.

■

Ultralow Voltage Reset: V_CC= 0.5V Guaranteed*

■

Monitors Six Inputs Simultaneously:

5V, 3.3V, 2.5V, 1.8V, ADJ1, ADJ2 (LTC2908-A1)

3.3V, 2.5V, 1.8V, 1.5V, ADJ1, ADJ2 (LTC2908-B1)

■

Guaranteed Threshold Accuracy: ±1.5% of

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 opera-

tion 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 pur-

pose solution for any kind of system requiring supply

monitors.
