Working with a 12 V BUS, setting the UVLO at 8.6 V can be very helpful to limit the input
current in case of BUS fall.

Adjustable masking time
By connecting the masking time pin to VCCDR or GND it is possible to select two different
values for the peak current protection leading edge blanking time. This is useful to avoid any
false OCP trigger due to spikes and oscillations generated at the turn-on of the high-side
MOSFET(s). The amount of this noise depends very much on the layout, MOSFETs, free-
wheeling diode, switched current, and input voltage.
When good layout and medium current are used, the minimum masking time can be
chosen, while in case of higher noise, it is better to select the maximum masking time. By
connecting the tMASK pin to VCCDR the masking time is about 400 ns, while connecting it to
GND results in about 260 ns masking time.

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 5 V BUS and 12 V busses
