Application information

DocID029238 Rev 4

25/37

Where :



VSENSE is voltage measurable on RSENSE resistor



ISENSE is current provided from CS pin in current output mode



IOUT is current flowing through output



K factor represents the ratio between PowerMOS cells and SenseMOS cells; its

spread includes geometric factor spread, current sense amplifier offset and process

parameters spread of overall circuitry specifying ratio between IOUT and ISENSE.

Failure flag indication

In case of power limitation/overtemperature, the fault is indicated by the CS pin which is

switched to a “current limited” voltage source, VSENSEH .

In any case, the current sourced by the CS in this condition is limited to ISENSEH
