MAX16066s can be cascaded hierarchically by using
one master device’s EN_OUT_s to control the EN

(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_.
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.
