Part Number : MAX809
Function : Very Low Supply Current 3-Pin Microprocessor Reset Monitor
Package : SOT-23, SOT-323 Type
Maker : ON Semiconductor
The MAX809 and MAX810 are cost−effective system supervisor circuits designed to monitor VCC in digital systems and provide a reset signal to the host processor when necessary.
No external components are required.
The reset output is driven active within 10 sec of VCC falling through the reset voltage threshold. Reset is maintained active for a timeout period which is trimmed by the factory after VCCrises above the reset threshold. The MAX810 has an active−high RESET output while the MAX809 has an active−low RESEToutput. Both devices are available in SOT−23 and SC−70 packages.
