EEPROM-Programmable Hex/Quad
Power-Supply Sequencers/Supervisors with ADC
MARGIN
MARGIN allows system-level testing while power sup-
plies exceed the normal ranges. Registers 41h and 42h
determine whether the programmable outputs assert to
a predetermined state or hold the last state as MARGIN
is driven low (Table 8). Drive MARGIN low to set the
programmable outputs in a known state while system-
level testing occurs. Leave MARGIN unconnected or
connect to DBP if unused. An internal 10μA current
source pulls MARGIN to DBP. The internal ADC contin-
ually monitors IN_ while MARGIN is low. The state of
each programmable output does not change while
MARGIN = GND. MARGIN overrides MR if both assert at
the same time.
