2 Pin Connections and Functions
L5988
4/8
12
VREF
Internally regulated voltage of 1.8V. It is used to provide a voltage reference for the
multifunction pin. Filter this pin to ground with at least 1
μF ceramic cap.
7ILIM-ADJ
Connecting a resistor between this pin and GND it is possible to increase the over
current protection threshold. Connecting a resistor between this pin and VREF it is
possible to decrease the over current protection threshold.
11
S/O/U
Multifunction pin. Depending on the voltage level at the input, with this pin it is
possible:
to enable-disable the sink mode current capability after soft-
start;
to enable-disable the latch mode for the OVP;
to set the UVLO threshold for the 3.3V BUS and 12V BUS.
(2.4V and 8V respectively);
The device continuously checks the analog value present at this pin and
sets the function according with the measured voltage.
