OVP_A threshold

R/W

These bits set the threshold for the OVP_A analog comparator. This threshold is programmable

from 0.75 V to 1.5 V. A setting of 0x00 corresponds to a 0.75 V threshold. A setting of 0x3F

corresponds to a 1.5 V threshold. Each LSB increments the threshold by 11.904 mV, as follows:

OVP Threshold = (Code × 0.75/63) + 0.75

Bit Name

R/W

Description

UVP_A flag

debounce time

R/W

This bit sets the UVP_A flag debounce time.

0 = 0 ms.

1 = 100 ms.

[6:0]

UVP_A threshold

R/W

These bits set the UVP_A threshold. The UVP_A flag is set when the UVP_A threshold is larger

than the seven MSBs of the VS_A value register (Register 0xFED5). Each LSB of the UVP_A

threshold corresponds to 12.5 mV. When these bits are set to 0, the UVP_A flag is always cleared.

UVP_B flag

debounce time

R/W

This bit sets the UVP_B flag debounce time.

0 = 0 ms.

1 = 100 ms.

UVP_B threshold

R/W

These bits set the UVP_B threshold. The UVP_B flag is set when the UVP_B threshold is larger

than the seven MSBs of the VS_B value register (Register 0xFED6). Each LSB of the UVP_B

threshold corresponds to 12.5 mV. When these bits are set to 0, the UVP_B flag is always cleared.
