AC_OK
This output is true when either AC
SENSE
1 or AC
SENSE
2 is true
(configurable). It can be configured as an open-drain N-channel
or P-channel MOSFET and as positive or negative (inverted)
logic. A pull-up or pull-down resistor is required. This pin can
be wire-ORed with the same pin on other ADM1041 ASICs in
the power supply. When the AC_OK pin is not used as such, it
can be configured as an analog input, MON5, or as a voltage
reference.
MON5
This is the alternative analog comparator function for the
AC_OK/V
REF
pin (Pin 18). The threshold is 2.5 V, and it has a
100 μA current source that allows hysteresis to be controlled by
adjusting the external source resistance. It is ideal for an OTP
sensing circuit using a thermistor as part of a voltage divider.
The OTP condition can be configured to latch off the power
supply (similar to OVP) or to allow an auto-restart (soft OTP).
See Figure 22.

Figure 22. Example of MON Pin Configuration
In the preceding example, MON2 and MON3 are configured to
monitor a negative 12 V rail. MON2 is configured as negative
going OVP, and MON3 is configured as positive going UVP.
The 5 V power rail is used for bias voltage.
