FUNCTIONAL DEVICE OPERATION
OPERATIONAL MODES
The 15XS3400 is in Fault mode when:
• V
• wake-up = 1,
• fail = X,
• fault=1.
This device indicates the faults below as they occur by
• Over-temperature fault,
• Over-current fault,
• Severe short-circuit fault,
• Output(s) shorted to VPWR fault in OFF state,
• Open load fault in OFF state,
• Over-voltage fault (enabled by default),
• Under-voltage fault.
The
Fault information is retained in the SPI fault register and is
