Over current protection

Over current threshold setting
L6728 allows to easily program a 1
st
level Over Current Threshold ranging from 50mV to
550mV, simply by adding a resistor (R
OCSET
) between LGATE and GND. 2
nd
level threshold
will be automatically set accordingly.
During a short period of time (about 5ms) following VCC rising over UVLO threshold, an
internal 10μA current (I
OCSET
) is sourced from LGATE pin, determining a voltage drop
across R
OCSET
. This voltage drop will be sampled and internally held by the device as 1
st
level Over Current Threshold. The OC setting procedure overall time length is about 5ms.
Connecting a R
OCSET
resistor between LGATE and GND, the programmed 1
st
level
threshold will be:
the programmed 2
nd
level threshold will be:
R
OCSET
values range from 5k
to 55k
.
In case R
OCSET
is not connected, the device sets the OCP thresholds to the maximum
values: an internal safety clamp on LGATE is triggered as soon as LGATE voltage reaches
600mV, setting the maximum threshold and suddenly ending OC setting phase.
