OVOUT_, and RESET) regardless of the voltage at any
monitored input. The state of each output does not
change while MARGIN = GND. While MARGIN is low,
the IC continues to monitor all voltages. When MARGIN
is deasserted, the outputs go to their monitored states
after a short propagation delay. The MARGIN input is
internally pulled up to V
CC
. Leave unconnected or con-
nect to V
CC
if unused.
Power-Supply Bypassing
The MAX16008/MAX16009 operate from a 2.0V to 5.5V
supply. An undervoltage lockout ensures that the out-
puts are in the correct states when the UVLO is
exceeded. In noisy applications, bypass V
CC
to ground
with a 0.1µF capacitor as close to the device as possi-
ble. In addition, the additional capacitor improves tran-
sient immunity. For fast-rising V
CC
transients, additional
capacitance may be required.
