Description

VOUT_UV_WARN_EN1

Default. Disables generation of SMBAlert when the VOUT_UV_WARN bit is set.

Generate SMBAlert when the VOUT_UV_WARN bit is set.

HS_INLIM_EN1

Default. Disables generation of SMBAlert when the HS_INLIM bit is set.

Generate SMBAlert when the HS_INLIM bit is set.

INVERT_SMBALERT_1

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.

CONVERT_EN

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.

GPO1_EN

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.

GPO1_DATA

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.

Description

FET_HEALTH_BAD_EN2

Disables generation of SMBAlert when the FET_HEALTH_BAD bit is set.

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.

IOUT_OC_FAULT_EN2

Default. Disables generation of SMBAlert when the IOUT_OC_FAULT bit is set.

Generate SMBAlert when the IOUT_OC_FAULT bit is set.

VIN_OV_FAULT_EN2

Default. Disables generation of SMBAlert when the VIN_OV_FAULT bit is set.

Generate SMBAlert when the VIN_OV_FAULT bit is set.

VIN_UV_FAULT_EN2

Default. Disables generation of SMBAlert when the VIN_UV_FAULT bit is set.

Generate SMBAlert when the VIN_UV_FAULT bit is set.

CML_ERROR_EN2

Default. Disables generation of SMBAlert when the CML_ERROR bit is set.

Generate SMBAlert when the CML_ERROR bit is set.

IOUT_OC_WARN_EN2

Default. Disables generation of SMBAlert when the IOUT_OC_WARN bit is set.

Generate SMBAlert when the IOUT_OC_WARN bit is set.

IOUT_WARN2_EN2

Default. Disables generation of SMBAlert when the IOUT_WARN2 bit is set.

Generate SMBAlert when the IOUT_WARN2 bit is set.

VIN_OV_WARN_EN2

Default. Disables generation of SMBAlert when the VIN_OV_WARN bit is set.

Generate SMBAlert when the VIN_OV_WARN bit is set.

VIN_UV_WARN_EN2

Default. Disables generation of SMBAlert when the VIN_UV_WARN bit is set.

Generate SMBAlert when the VIN_UV_WARN bit is set.

VOUT_OV_WARN_EN2

Default. Disables generation of SMBAlert when the VOUT_OV_WARN bit is set.

Generate SMBAlert when the VOUT_OV_WARN bit is set.

VOUT_UV_WARN_EN2

Default. Disables generation of SMBAlert when the VOUT_UV_WARN bit is set.

Generate SMBAlert when the VOUT_UV_WARN bit is set.

HS_INLIM_EN2

Default. Disables generation of SMBAlert when the HS_INLIM bit is set.

Generate SMBAlert when the HS_INLIM bit is set.

INVERT_SMBALERT_2

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.
