Bits Bit Name Settings Description
5 VOUT_UV_WARN_EN1 0 Default. Disables generation of SMBAlert when the VOUT_UV_WARN bit is set.
1 Generate SMBAlert when the VOUT_UV_WARN bit is set.
4 HS_INLIM_EN1 0 Default. Disables generation of SMBAlert when the HS_INLIM bit is set.
1 Generate SMBAlert when the HS_INLIM bit is set.
3
INVERT_SMBALERT_1
0
Default. SMBAlert is active low when a fault/warning bit that is enabled becomes set.
1 SMBAlert is active high when a fault/warning bit that is enabled becomes set.
2 CONVERT_EN 0
Default. GPO1/
ALERT1/CONV is configured as an output pin.
1
GPO1/
ALERT1/CONV is configured as an input pin. All other settings in ALERT1_CONFIG
are ignored.
1 GPO1_EN 0
Default. GPO1/
ALERT1/CONV can be configured as either a power monitor convert
input or an SMBAlert output.
1
GPO1/
ALERT1/CONV is configured as a general-purpose output unless CONVERT_EN is
set to 1.
0 GPO1_DATA 0
Default. Sets GPO1/
ALERT1/CONV low when configured as a general-purpose output.
1
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.

Bits Bit Name Settings Description
15 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.
14 IOUT_OC_FAULT_EN2 0 Default. Disables generation of SMBAlert when the IOUT_OC_FAULT bit is set.
1 Generate SMBAlert when the IOUT_OC_FAULT bit is set.
13 VIN_OV_FAULT_EN2 0 Default. Disables generation of SMBAlert when the VIN_OV_FAULT bit is set.
1 Generate SMBAlert when the VIN_OV_FAULT bit is set.
12 VIN_UV_FAULT_EN2 0 Default. Disables generation of SMBAlert when the VIN_UV_FAULT bit is set.
1 Generate SMBAlert when the VIN_UV_FAULT bit is set.
11 CML_ERROR_EN2 0 Default. Disables generation of SMBAlert when the CML_ERROR bit is set.
1 Generate SMBAlert when the CML_ERROR bit is set.
10
IOUT_OC_WARN_EN2
0
Default. Disables generation of SMBAlert when the IOUT_OC_WARN bit is set.
1 Generate SMBAlert when the IOUT_OC_WARN bit is set.
9 IOUT_WARN2_EN2 0 Default. Disables generation of SMBAlert when the IOUT_WARN2 bit is set.
1 Generate SMBAlert when the IOUT_WARN2 bit is set.
8 VIN_OV_WARN_EN2 0 Default. Disables generation of SMBAlert when the VIN_OV_WARN bit is set.
1 Generate SMBAlert when the VIN_OV_WARN bit is set.
7 VIN_UV_WARN_EN2 0 Default. Disables generation of SMBAlert when the VIN_UV_WARN bit is set.
1 Generate SMBAlert when the VIN_UV_WARN bit is set.
6 VOUT_OV_WARN_EN2 0 Default. Disables generation of SMBAlert when the VOUT_OV_WARN bit is set.
1 Generate SMBAlert when the VOUT_OV_WARN bit is set.
5 VOUT_UV_WARN_EN2 0 Default. Disables generation of SMBAlert when the VOUT_UV_WARN bit is set.
1
Generate SMBAlert when the VOUT_UV_WARN bit is set.
4 HS_INLIM_EN2 0 Default. Disables generation of SMBAlert when the HS_INLIM bit is set.
1 Generate SMBAlert when the HS_INLIM bit is set.
3 INVERT_SMBALERT_2 0 Default. SMBAlert is active low when a fault/warning bit that is enabled becomes set.
1 SMBAlert is active high when a fault/warning bit that is enabled becomes set.
2 Reserved 0 Always reads as 0.
