ILIM

This pin cannot be left floating and can be used to program the limitation current value through an external

resistor (RILIM) see Table 8. Protection and diagnostic. The resistor RILIM has to be connected between ILIM and

SGND pins. When the IPS4260L ICs are used in the same application, their ILIM pins cannot be wired together:

each IC must be connected to its own resistor ( see Section 6.3 Current limitation and cut-off )

2.9

CoD

This pin cannot be left floating and can be used to program the cut-off delay time tcoff (see Table 8. Protection and

diagnostic) through an external resistor (RCoD). The resistor RCoD has to be connected between CoD and SGND

pins. The cut-off function can be completely disabled by shorting CoD pin to SGND: in this condition the power

stage channel remains ON in limitation condition, supplying the current to the load until the input is forced LOW or

the thermal shutdown threshold is triggered (see Section 6.3 Current limitation and cut-off )
