Description
Live register.
There are no active status bits to be read by STATUS_INPUT.
There are one or more active status bits to be read by STATUS_INPUT.
Live register.
There are no active status bits to be read by STATUS_MFR_SPECIFIC.
There are one or more active status bits to be read by
STATUS_MFR_SPECIFIC.
Live register.
The voltage on the DRAIN pin is above the required threshold,
indicating that output power is considered good. This bit is the
logical inversion of the PWRGD pin on the part.
The voltage on the DRAIN pin is below the required threshold,
indicating that output power is considered bad.
Always reads as 000.
This byte is the same as the byte returned by the STATUS_BYTE
command.
Description
Latched register.
No overcurrent output fault detected.
The hot swap controller detected an overcurrent condition and the
time limit set by the capacitor on the TIMER pin has elapsed, causing
the hot swap gate drive to shut down.
Always reads as 0.
Latched register.
No overcurrent condition on the output supply detected by the
power monitor using the IOUT_OC_WARN_LIMIT command.
An overcurrent condition was detected by the power monitor using
the IOUT_OC_WARN_LIMIT command.
Always reads as 00000.
Description
Latched register.
No overvoltage detected on the OV pin.
An overvoltage was detected on the OV pin.
Latched register.
No overvoltage condition on the input supply detected by the
power monitor.
An overvoltage condition on the input supply was detected by the
power monitor.
Latched register.
No undervoltage condition on the input supply detected by the
power monitor.
An undervoltage condition on the input supply was detected by the
power monitor.
