Force-On Function
When the force-on bit for a channel is set to 1 in register
foset[1:0] (see Table 45), the channel is enabled regard-
less of the ON_ voltage or the Chx_EN1 and Chx_EN2
bits in register chxen. In forced-on operation, all func-
tions operate normally with the notable exception that the
channel does not shut down due to any fault conditions
that may arise.
Table 45. Force-On Control Register Format
There is a Force-On Key register fokey that must be set
to 0xA5 in order for the Force-On function to become
active (see Table 46). If this register contains any value
other than 0xA5, writing 1 to the Force-On bits in regis-
ter foset has no effect. This provides protection against
accidental force-on operation that might otherwise be
caused by an erroneous I 2 C write.

Fault Logging and Indications
The MAX5970 provides detailed information about any
fault conditions that have occurred. Independent FAULT_
outputs specifically indicate circuit-breaker shutdown
events, while an ALERT output is asserted whenever a
Fault Dependency
If a fault event occurs (digital UV warning/critical, digital
OV warning/critical, or digital overcurrent warning), the
fault is logged by setting a corresponding bit in registers
fault1 or fault2 (see Tables 47, 48, and 49).
