Description
Reserved.
This bit specifies whether the blanking time for the CS1_B OCP comparator is referenced to the
rising edge of OUT6.
0 = no blanking at OUT6 rising edge.
1 = blanking time referenced to OUT6 rising edge.
This bit specifies whether the blanking time for the CS1_B OCP comparator is referenced to the
rising edge of OUT5.
0 = no blanking at OUT5 rising edge.
1 = blanking time referenced to OUT5 rising edge.
This bit specifies whether the blanking time for the CS1_B OCP comparator is referenced to the
rising edge of OUT2.
0 = no blanking at OUT2 rising edge.
1 = blanking time referenced to OUT2 rising edge.
This bit specifies whether the blanking time for the CS1_B OCP comparator is referenced to the
rising edge of OUT1.
0 = no blanking at OUT1 rising edge.
1 = blanking time referenced to OUT1 rising edge.
Description
Reserved.
When this bit is set, an OCP signal on the channel to which OUT8 is assigned causes OUT8 to
turn on. The falling edge of the SR output still follows the programmed value.
When this bit is set, an OCP signal on the channel to which OUT7 is assigned causes OUT7 to
turn on. The falling edge of the SR output still follows the programmed value.
When this bit is set, an OCP signal on the channel to which OUT4 is assigned causes OUT4 to
turn on. The falling edge of the SR output still follows the programmed value.
When this bit is set, an OCP signal on the channel to which OUT3 is assigned causes OUT3 to
turn on. The falling edge of the SR output still follows the programmed value.
Description
1 = negative gain is introduced.
0 = positive gain is introduced.
This value calibrates the primary side current sense gain. For more information, see the CS,
CS1_A, and CS1_B Gain Trim section.
Description
Setting this bit causes the CS OCP comparator output to be ignored. The flag is always cleared.
These bits specify the blanking time. During this time, the CS OCP comparator output is
ignored. The CS OCP blanking time is measured from OUT1 and OUT2.
