Description
Default. Disables generation of SMBAlert when the VOUT_UV_WARN bit is set.
Generate SMBAlert when the VOUT_UV_WARN bit is set.
Default. Disables generation of SMBAlert when the HS_INLIM bit is set.
Generate SMBAlert when the HS_INLIM bit is set.
Default. SMBAlert is active low when a fault/warning bit that is enabled becomes set.
SMBAlert is active high when a fault/warning bit that is enabled becomes set.
Default. GPO1/ALERT1/CONV is configured as an output pin.
GPO1/ALERT1/CONV is configured as an input pin. All other settings in ALERT1_CONFIG
are ignored.
Default. GPO1/ALERT1/CONV can be configured as either a power monitor convert
input or an SMBAlert output.
GPO1/ALERT1/CONV is configured as a general-purpose output unless CONVERT_EN is
set to 1.
Default. Sets GPO1/ALERT1/CONV low when configured as a general-purpose output.
Sets GPO1/ALERT1/CONV high when configured as a general-purpose output.
ALERT2_CONFIG
Code: 0xD6, read/write word. Value after reset: 0x8000.
This command is supported on the ADM1275-1 and the ADM1275-3. The ADM1275-2 does not have a GPO2/ALERT2 pin.

FET_HEALTH_BAD_EN2
0 Disables generation of SMBAlert when the FET_HEALTH_BAD bit is set.
1 Default. Generate SMBAlert when the FET_HEALTH_BAD bit is set. This bit is active
from power-up so that a FET problem can be detected and flagged immediately
without the need for software to set this bit.
