PIN FUNCTIONS
1. POWERSUPPLY
Supplyvoltageinput.Whenthe supply reachesthe
maximum operatingvoltage(32V)thedeviceis tur-
ned off, protecting itself andthe load.
Turningoff guaranteedfor V
S
> 41V.
2. INPUT

sticoutputreducingto the minimumvaluethequie-
scent current.
3. GROUND
This pin mustbe connectedto ground.
4. DIAGNOSTICFEEDBACK
The diagnosticcircuit is active in inputhigh level
condition.ThisoutputdetectswithTipically45ms
delayat T
amb

°
C thefollowingfaults:
-
Overvoltagecondition.
-
Thermalshutdown.
-
Shortcircuit.Thepowerstagecurrentisinternally
limitedat 25A.
-
Open load. The openload conditionis detected
withload current < 0.6A.
The diagnosticoutput is activelow. The diagnostic
delay timeallows to avoidspuriousdiagnosys(i.e :
turn ON overcurrent,overvoltagespikes etc.).
5. POWEROUTPUT
The device is provided with short circuit protection
