VOUT_OV_WARN_LIMIT

The VOUT_OV_WARN_LIMIT command sets the value, in volts, of the output voltage measured by the ADC at the

VSENSE± pins that causes an output overvoltage warning. If the VOUT_OV_WARN_LIMIT is exceeded, the device:

• Sets the VOUT Bit in the STATUS_WORD

• Sets the VOUT Overvoltage Warning Bit in the STATUS_VOUT Command

• Notifies the Host by Asserting ALERT, Unless Masked

This command has two data bytes in Linear_16u format.

VOUT_UV_WARN_LIMIT

The VOUT_UV_WARN_LIMIT command sets the value, in volts, of the output voltage measured by the ADC at the

VSENSE± pins that causes an output undervoltage warning. If the VOUT_UV_WARN_LIMIT is exceeded, the device:

• Sets the VOUT Bit in the STATUS_WORD

• Sets the VOUT Undervoltage Warning Bit in the STATUS_VOUT Command

• Notifies the Host by Asserting ALERT, Unless Masked

This command has two data bytes in Linear_16u format.

VOUT_UV_FAULT_LIMIT

The VOUT_UV_FAULT_LIMIT command sets the value of the output voltage measured by the UV supervisor at the

VSENSE± pins, in volts, which causes an output undervoltage fault.

This command has two data bytes in Linear_16u format.
