slot on different devices will not come up in the desired
order even if the sequence delays are identical.
U Consider using an external FP to control the EN inputs
or the software enable bits of cascaded devices,
monitoring the RESET outputs as a power-good signal.
U For a large number of voltage rails, the MAX16065/
MAX16066s can be cascaded hierarchically by using
one master device’s EN_OUT_s to control the EN
inputs of several slave devices.
Controlling Power Supplies Without
Using the Sequencer
A FP may control power supplies manually without
involving the sequencing slot system by controlling
EN_OUT_s configured as GPIO_. The output of a power
supply controlled this way can be monitored using a
MON_ input configured as “Monitoring Only(Primary
Sequence)” or “Monitoring Only(Secondary Sequence)”
(see the Monitoring Inputs while Sequencing section). To
monitor the supply for critical faults, the FP will need to
manually set the critical fault enable bit in r6Eh to r72h
after turning on the EN_OUT_, and manually clear the
critical fault enable bit before turning off the EN_OUT_.
Monitoring Current Using the
Differential Inputs
The MAX16065/MAX16066 can monitor up to seven
currents using the dedicated current-sense amplifier as
well as up to six pairs of inputs configured in differential
mode. The accuracy of the differential pairs is limited by
the voltage range and the 10-bit conversions. Each input
pair uses an odd-numbered MON_ input in combination
with an even-numbered MON_ input to monitor both the
voltage from the odd-numbered MON_ to ground and
the voltage difference between the two MON_ inputs.
