General Description

The MAX6854/MAX6855/MAX6856/MAX6858/MAX6860– MAX6869 ultra-low-current (170nA, typ) microprocessor (µP) supervisory circuits combine voltage monitoring, watchdog timer, and manual reset input functions in a 5pin SOT23 package.

These devices assert a reset signal whenever the monitored voltage drops below the factorytrimmed reset threshold voltage, manual reset is asserted, or the watchdog timer expires.

The reset output remains asserted for a minimum timeout period after VCC rises above the reset threshold and manual reset is deasserted.
