STATUS_WORD
Code: 0x79, read word. Value after reset: 0x0000.
Table 20. Bit Descriptions for STATUS_WORD Command
Bits Bit Name Behavior Settings Description
[15] VOUT_STATUS Live 0 There are no active status bits to be read by STATUS_VOUT.
1 There are one or more active status bits to be read by STATUS_VOUT.
[14]
IOUT_STATUS
Live
0
There are no active status bits to be read by STATUS_IOUT.
1 There are one or more active status bits to be read by STATUS_IOUT.
[13] INPUT_STATUS Live 0 There are no active status bits to be read by STATUS_INPUT.
1
There are one or more active status bits to be read by STATUS_INPUT.
[12] MFR_STATUS Live 0 There are no active status bits to be read by STATUS_MFR_SPECIFIC.
1 There are one or more active status bits to be read by STATUS_MFR_SPECIFIC.
[11] POWER_GOOD# Live 0
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.
1
The voltage on the FLB pin is below the required threshold, indicating
that output power is considered bad.
[10:8] Reserved 000 Always reads as 000.
[7:0] STATUS_BYTE This byte is the same as the byte returned by the STATUS_BYTE command.
STATUS_VOUT
Code: 0x7A, read byte. Value after reset: 0x00.
Table 21. Bit Descriptions for STATUS_VOUT Command
Bits Bit Name Behavior Settings Description
[7] Reserved 0 Always reads as 0.
[6] VOUT_OV_WARN Latched 0
No overvoltage condition on the output supply detected by the power
monitor.
1
An overvoltage condition on the output supply was detected by the
power monitor.
[5] VOUT_UV_WARN Latched 0
No undervoltage condition on the output supply detected by the power
monitor.
1
An undervoltage condition on the output supply was detected by the
power monitor.
[4:0] Reserved 00000 Always reads as 00000.
STATUS_IOUT
Code: 0x7B, read byte. Value after reset: 0x00.
Table 22. Bit Descriptions for STATUS_IOUT Command
Bits Bit Name Behavior Settings Description
[7] IOUT_OC_FAULT Latched 0 No overcurrent output fault detected.
1
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.
[6] Reserved 0 Always reads as 0.
[5] IOUT_OC_WARN Latched 0
No overcurrent condition on the output supply detected by the power
monitor using the IOUT_OC_WARN_LIMIT command.
1
An overcurrent condition was detected by the power monitor using the
IOUT_OC_WARN_LIMIT command.
[4:0] Reserved 00000 Always reads as 00000.
