SUMMARY DESCRIPTION

The STM1001 MICROPROCESSOR RESET Circuit is a low-power supervisory device used to monitor power supplies. It performs a single function: asserting a reset signal whenever the VCC supply voltage drops below a preset value and keeping it asserted until VCC has risen above the preset threshold for a minimum period of time (trec).

FEATURES SUMMARY

■ PRECISION MONITORING OF 3V, 3.3V, and 5V SUPPLY VOLTAGES

■ 140ms RESET PULSE WIDTH (MIN)

■ LOW SUPPLY CURRENT - 6µA (TYP)

■ GUARANTEED RST ASSERTION DOWN TO VCC = 1.0V

■ OPERATING TEMPERATURE: –40°C to 85°C (Industrial Grade)
