The MAX16047A/MAX16049A include selectable internal
100
pulldown resistors to ensure that tracked voltages
are not held high by large external capacitors during a
fault event. The pulldowns help to ensure that monitored
INS_ voltages are fully discharged before the next
power-up cycle is initiated. These pulldowns are high
impedance during normal operation. Set r4Eh[7:4] to ‘1’
to enable the pulldown resistors (Table 12). These pull-
down resistors may also be used with EN_OUT1–
EN_OUT4 channels not configured for closed-loop track-
ing, which is useful to discharge the output capacitors of
a DC-DC converter during shutdown. For this case, con-
figure the GPIO as an INS_ input and set the 100
pull-
down bit, but do not enable closed-loop tracking.
Connect the INS_ input to the output of the power supply.
