Description
Disables generation of an SMBAlert when the FET_HEALTH_BAD bit is set.
Default. Generates SMBAlert when the FET_HEALTH_BAD bit is set. This bit is active
from power-up for a FET problem to be detected and flagged immediately without the
need for software to set this bit.
Default. Disables generation of an SMBAlert when the IOUT_OC_FAULT bit is set.
Generates an SMBAlert when the IOUT_OC_FAULT bit is set.
Default. Disables generation of an SMBAlert when the VIN_OV_FAULT bit is set.
Generates an SMBAlert when the VIN_OV_FAULT bit is set.
Generates an SMBAlert when the VIN_UV_FAULT bit is set.
Default. Disables generation of an SMBAlert when the CML_ERROR bit is set.
Generates an SMBAlert when the CML_ERROR bit is set.
Default. Disables generation of an SMBAlert when the IOUT_OC_WARN bit is set.
Generates an SMBAlert when the IOUT_OC_WARN bit is set.
Default. Disables generation of an SMBAlert when the IOUT_WARN2 bit is set.
Generates an SMBAlert when the IOUT_WARN2 bit is set.
Default. Disables generation of an SMBAlert when the VIN_OV_WARN bit is set.
Generates an SMBAlert when the VIN_OV_WARN bit is set.
Default. Disables generation of an SMBAlert when the VIN_UV_WARN bit is set.
Generates an SMBAlert when the VIN_UV_WARN bit is set.
Default. Disables generation of an SMBAlert when the VOUT_OV_WARN bit is set.
Generates an SMBAlert when the VOUT_OV_WARN bit is set.
Generates an SMBAlert when the VOUT_UV_WARN bit is set.
Generates an SMBAlert when the HS_INLIM bit is set.
Default. Disables generation of an SMBAlert when the PIN_OP_WARN bit is set.
Generates an SMBAlert when the PIN_OP_WARN bit is set.
Default. GPO2 is configured to generate SMBAlerts.
GPO2 can be used as a general-purpose digital output pin. The GPO2_INVERT bit is
used to change the output state.
Reserved.
GPO2 is configured for digital comparator mode. The output pin continuously shows
for the selected warning(s) if the relevant warning threshold has been exceeded. In
effect, this is an unlatched SMBAlert. If multiple bits are selected, the output values are
OR’ed together. Only warning threshold comparisons affect the pin in this mode. If
other bits such as VIN_UV_FAULT_EN2 are set, they are ignored in this mode of
operation.
Default. The GPO2 pin is active low.
GPO2 is active high.
Default. Disables generation of an SMBAlert when the VIN_UV_FAULT bit is set.
Default. Disables generation of an SMBAlert when the VOUT_UV_WARN bit is set.
Default. Disables generation of an SMBAlert when the HS_INLIM bit is set.
