Reset Output
A μP’s reset input starts the μP in a known state.
Whenever the μP is in an unknown state, it should be
held in reset. The MAX814/MAX815/MAX816 assert reset
during power-up, power-down, or brownout conditions.
On power-up, once V
CC
reaches 1V, RESET is a guar-
anteed logic low of 0.4V or less. As V
CC
rises, RESET
stays low. As V
CC
rises above the reset threshold, an
internal timer releases RESET after 200ms. RESET also
pulses low whenever V
CC
dips below the reset thresh-
old (i.e., brownout condition). If brownout occurs in the
middle of a previously initiated reset, the internal timer
is reset and the output remains low for at least another
140ms after the brownout ends. On power-down, once
V
CC
falls below the reset threshold, RESET stays low
and is guaranteed to be less than 0.3V until V
CC
drops
below 1V.
The MAX814 and MAX816 also offer active-high RESET
outputs. They are the inverse of the RESEToutputs.
