VOUT_OV_FAULT_LIMIT (40h)

Definition: Sets the VOUT overvoltage fault threshold.

Data Length in Bytes: 2

Data Format: L16u

Type: R/W

Default Value: 1.15xVOUT_COMMAND pin strap setting

Units: V

Range: 0V to VOUT_MAX

VOUT_OV_FAULT_RESPONSE (41h)

Definition: Configures the VOUT overvoltage fault response. Note that the device cannot be set to ignore this fault mode.

Data Length in Bytes: 1

Data Format: BIT

Type: R/W

Default Value: 80h (Disable and no retry)

Units: N/A

VOUT_OV_WARN_LIMIT (42h)

Definition: Sets the VOUT overvoltage warning threshold. The power-good signal is pulled low when output voltage goes higher than this

threshold.

Data Length in Bytes: 2

Data Format: L16u

Type: R/W

Default Value: 1.10xVOUT_COMMAND pin strap setting

Units: V

Range: 0V to VOUT_MAX

VOUT_UV_WARN_LIMIT (43h)

Definition: Sets the VOUT undervoltage warning threshold. The power-good signal is pulled low when output voltage goes lower than this

threshold.

Data Length in Bytes: 2

Data Format: L16u

Type: R/W

Default Value: 0.90xVOUT_COMMAND pin strap setting

Units: V

Range: 0V to VOUT_MAX

VOUT_UV_FAULT_LIMIT (44h)

Definition: Sets the VOUT undervoltage fault threshold. This fault is masked during ramp or when disabled.

Data Length in Bytes: 2

Data Format: L16u

Type: R/W

Default Value: 0.85xVOUT_COMMAND pin strap setting

Units: V

Range: 0V to VOUT_MAX

SETTINGS
