Charge-Pump Configuration
EN_OUT1–EN_OUT6 can act as high-voltage charge-
pump outputs to drive up to six external n-channel
MOSFETs. During sequencing, an EN_OUT_ output
configured this way drives 6μA until the voltage reach-
es 5V above the corresponding MON_ to fully enhance
the external n-channel MOSFET. For example,
EN_OUT2 will rise to 5V above MON2. See the
Sequencing section for more detailed information on
power-supply sequencing.
Closed-Loop Tracking Operation
EN_OUT1–EN_OUT4 can operate in closed-loop track-
ing mode. When configured for closed-loop tracking,
EN_OUT1–EN_OUT4 are capable of driving the gates
of up to four external n-channel MOSFETs. For closed-
loop tracking, configure GPIO1–GPIO4 as return-sense
line inputs (INS_) to be used in conjunction with
EN_OUT1 –EN_OUT4 and MON1 –MON4. See the
Closed-Loop Tracking section.
Open-Drain Output Configuration
Connect an external pullup resistor from the output to
an external voltage up to 6V (abs max, EN_OUT7 –
EN_OUT12) or 12V (abs max, EN_OUT1–EN_OUT6)
when configured as an open-drain output. Choose the
pullup resistor depending on the number of devices
connected to the open-drain output and the allowable
current consumption. The open-drain output configura-
tion allows wire-ORed connection.
Push-Pull Output Configuration
The MAX16047/MAX16049s ’ programmable outputs
sink 2mA and source 100μA when configured as push-
pull outputs.
EN_OUT_ State During Power-Up
When V CC is ramped from 0V to the operating supply
voltage, the EN_OUT_ output is high impedance until
V CC is approximately 2.4V and then EN_OUT_ will be in
its configured deasserted state. See Figures 3 and 4.
RESET is configured as an active-low open-drain out-
put pulled up to V CC through a 10k Ω resistor for
Figures 3 and 4.
