SUMMARY DESCRIPTION
The STM809/810/811/812 MICROPROCESSOR RESET Circuits are low-power supervisory devices used to monitor power supplies. They perform a single function: asserting a reset signal whenever the VCCsupply voltage drops below a preset value and keeping it asserted until VCChas risen above the preset threshold for a minimum period of time (trec). The STM811/812 also provide a push-button reset input (MR).
FEATURES SUMMARY
■ PRECISION MONITORING OF 3V, 3.3V, and 5V SUPPLY VOLTAGES
■ TWO OUTPUT CONFIGURATIONS
– Push-pull RSTOutput (STM809/811)
– Push-pull RST Output (STM810/812)
■ 140ms RESET PULSE WIDTH (MIN)
■ LOW SUPPLY CURRENT - 6µA (TYP)
■ GUARANTEED RST/RST ASSERTION DOWN TO VCC= 1.0V
■ OPERATING TEMPERATURE: –40°C to 85°C (Industrial Grade)
■ LEAD-FREE, SMALL SOT23 and SOT143 PACKAGE
