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.
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.

EN_OUT10 Configuration*:
00 = EN_OUT10 is an open-drain active-low output
01 = EN_OUT10 is an open-drain active-high output
10 = EN_OUT10 is a push-pull active-low output
11 = EN_OUT10 is a push-pull active-high output
EN_OUT11 Configuration*:
00 = EN_OUT11 is an open-drain active-low output
01 = EN_OUT11 is an open-drain active-high output
10 = EN_OUT11 is a push-pull active-low output
11 = EN_OUT11 is a push-pull active-high output
EN_OUT12 Configuration*:
00 = EN_OUT12 is an open-drain active-low output
01 = EN_OUT12 is an open-drain active high output
10 = EN_OUT12 is a push-pull active-low output
11 = EN_OUT12 is a push-pull active-high output

Connect an external pullup resistor from the output to
an external voltage up to 6V (abs max, EN_OUT7 to
EN_OUT12) or 12V (abs max, EN_OUT1 to 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.
The MAX16046A/MAX16048As’ programmable outputs
sink 2mA and source 100µA when configured as push-
pull outputs.
