DESCRIPTION

The LTC699 provides power supply monitoring for microprocessor-based systems. The features include microprocessor reset and watchdog timing. Precise internal voltage reference and comparator circuit monitor the power supply line. When an out-of-tolerance condition occurs, the RESET output is forced to active low. In addition, the RESET output is guaranteed to remain logic low even with VCC as low as 1V.

FEATURES

■ Guaranteed Reset Assertion at VCC = 1V
■ 1.5mA Maximum Supply Current
■ SO-8 Packaging
■ 4.65V Precision Voltage Monitor
■ Power OK/Reset Time Delay: 200ms
■ Minimum External Component Count
■ Performance Specified Over Temperature
■ Superior Upgrade for MAX699

APPLICATIONS

■ Critical µP Power Monitoring
■ Intelligent Instruments
■ Computers and Controllers
■ Automotive Systems
