Device description
27/52
5.10
Multifunction pin (S/O/U L6730) (CC/O/U L6730B)
With this pin it is possible:
to enable disable the sink mode current capability (L6730) or the constant current
protection (L6730B) at the end of the soft-start.
to enable or disable the latch-mode for the OVP.
to set the UVLO threshold for 5V BUS and 12V Busses.
Table 6 shows how to set the different options through an external resistor divider:
