Voltage Tracking Sense (INS_) Inputs
GPIO1–GPIO4 are configurable as feedback sense
return inputs (INS_) for closed-loop tracking. Connect the
gate of an external n-channel MOSFET to each EN_OUT_
configured for closed-loop tracking. Connect INS_ inputs
to the source of the MOSFETs for tracking feedback.
Internal comparators monitor INS_ with respect to a
control tracking ramp voltage for power-up/power-down
and control each EN_OUT_ voltage. Under normal con-
ditions each INS_ voltage tracks the ramp voltage until
the power-good voltage threshold has been reached.
The slew rate for the ramp voltage and the INS_ to
MON_ power-good threshold are programmable. See
the Closed-Loop Tracking section.
INS_ connections can also act as 100
Ω
pulldowns for
closed-loop tracking channels or for other power sup-
plies, if INS_ are connected to the outputs of the sup-
plies. Set the appropriate bits in r4Eh[7:4] to enable
pulldown functionality. See Table 13.
General-Purpose Logic Inputs/Outputs
Configure GPIO1–GPIO6 be used as general-purpose
inputs/outputs. Write values to GPIOs through r1Ah
when operating as outputs, and read values from r1Bh
when operating as inputs. Register r1Bh is read-only.
See Table 6 for more information on reading and writing
to the GPIOs as logic inputs/outputs. Both registers
r1Ah and r1Bh are located in the extended page and
are therefore not loaded from EEPROM on boot-up.
