Description
Always reads as 0.
The hot swap gate drive output is enabled.
The hot swap gate drive output is disabled, and the GATE pin is pulled
down. This can be due to, for example, an overcurrent fault that causes
the ADM1276 to latch off, an undervoltage condition on the UV pin, or
the use of the OPERATION command to turn the output off.
Always reads as 0.
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.
No undervoltage input fault detected on the UV pin.
An undervoltage input fault was detected on the UV pin.
Always reads as 0.
No communications error detected on the I
An error was detected on the I
unsupported command, an invalid PEC byte, and an incorrectly
structured message.
No other active status bit to be reported by any other status command.
Active status bits are waiting to be read by one or more status commands.
