Description
There are no active status bits to be read by STATUS_VOUT.
There are one or more active status bits to be read by STATUS_VOUT.
There are no active status bits to be read by STATUS_IOUT.
There are one or more active status bits to be read by STATUS_IOUT.
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.
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.
The voltage on the FLB 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 FLB 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
Always reads as 0.
No overvoltage condition on the output supply detected by the power
monitor.
An overvoltage condition on the output supply was detected by the
power monitor.
No undervoltage condition on the output supply detected by the power
monitor.
An undervoltage condition on the output supply was detected by the
power monitor.
Always reads as 00000.
Description
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.
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.
