MAX810LTRG

Very Low Supply Current  3-Pin Microprocessor  Reset Monitors

监控电路 4.63V uP Reset

The MAX810LTRG 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 VCC rises above

the reset threshold. The MAX810 has an active−high RESET output

while the MAX809 has an active−low RESET output. Both devices

are available in SOT−23 and SC−70 packages.
