MARGIN allows system-level testing while power sup-
plies are adjusted from their nominal voltages. Drive
MARGIN low to deassert all outputs (UVOUT_,
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
nect to V
The MAX16063 features a V
(UVLO) that preserves a reset status even if V
low as 1V. The undervoltage lockout circuitry monitors
the voltage at V
threshold (typically 1.735V), RESET is asserted and all
