Common error states and their meaning are summarized below. Refer to the MAX15500 IC data sheet for full
details on the error detection capabilities and register behavior.
When operating in voltage
modes, the Short Circuit error is
asserted if the respective output
is shorted to analog ground.
If the short circuit condition has
been resolved, a subsequent
Refresh asserts both the
Intermittent Fault and Short Circuit
errors. A second Refresh clears
the error unless the short circuit
condition has returned.
If the short circuit condition
remains, the error remains
asserted as shown above.
When operating in current
modes, the Open Load error is
asserted if there is an open
circuit in the current loop for the
respective output.
If the open load condition has
been resolved, a subsequent
Refresh asserts both the
Intermittent Fault and Open Load
errors. A second Refresh clears
the error unless the open load
condition has returned.
If the open load condition
remains, the error remains
asserted as shown above.
If the Intermittent Fault error is
ever asserted, one or more of the
other asserted error conditions
has cleared before the user read
the status register.
A subsequent Refresh clears the
intermittent errors and leaves any
persistent error alarms asserted.
