Readback Operations
Write to the command addresses 4h or 5h to read back the
configuration register data or the internal error information
through DOUT[9:0]. For error readback operations, each
bit corresponds to a specific error condition, with multiple
bits indicating multiple error conditions present.
Intermittent Errors
An intermittent error is defined as an error that is detected
and is resolved before the error register is read back.
When the error is resolved without intervention, the inter-
mittent bit (bit 9) is set. The output short-circuit and output
open-load errors trigger the intermittent bit. Internal over-
temperature and supply voltage brownout do not trigger
the intermittent bit.
Error Reporting Applications
The ERROR output is typically connected to an inter-
rupt input of the system microcontroller. The MAX15500/
MAX15501 only issue an interrupt when a new error con-
dition is detected. The devices do not issue interrupts
when errors (either individual or multiple) are resolved
or when already reported errors persist. The system
microcontroller resets ERROR when the system micro-
controller reads back the error register. ERROR does not
assert again unless a different error occurs.
