LTC1232C Hoja de datos - Linear Technology

DESCRIPTION
The LTC1232 provides power supply monitoring, watchdog timing and external reset for microprocessor systems. A precise internal voltage reference and comparator circuit monitor the power supply line. When an out-of-tolerance condition occurs, the reset outputs are forced to active states. The RST output is guaranteed to remain logic low even with VCC as low as 1V.

FEATURES
■ Guaranteed Reset Assertion at VCC = 1V
■ 8-Pin SO Plastic Package
■ 2.0mA Maximum Supply Current
■ 4.62V/4.37V Precision Voltage Monitor
■ Power OK/Reset Time Delay: 600ms
■ Minimum External Component Count
■ Superior Upgrade for DS1232

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