Table 10. Right-Channel Mask Register
MSVDDR: Set MSVDDR to 1 to enable the short to V
MSGNDR: Set MSGNDR to 1 to enable the short to GND detection on the right channel.
MLIMITR: Set MLIMITR to 1 to enable overcurrent detection on the right channel.
MOFFSETR: Set MOFFSETR to 1 to enable excessive-offset detection on the right channel.
MOPENR: Set MOPENR to 1 to enable open-load detection on the right channel.
When the DIAG bit and the appropriate mask bits are set
to 1, the MAX13325/MAX13326 enter diagnostic mode.
In this mode, the MAX13325/MAX13326 detect short
to GND, short to battery, overcurrent condition, over-
temperature condition, excessive offset, and report the
diagnosis using the I
the FLAG output.

For stand-alone mode, there exists a 500ms stand-alone
fault retry function (for autoretry) until the fault goes
away. The FLAG output is pulsed to indicate a fault.
When in diagnostic mode, the MAX13325/MAX13326
detect if any of the differential outputs is shorted to V
or battery. Upon detection of the short to V
the faulted channel is switched off and its output goes
into a high-impedance state. The fault is reported using
