In case of a detected overtemperature, only the corre-
sponding channel is disabled. The other channel stays
enabled.
The RETURNx is switched off if the voltage at RE-
TURNx is higher than 2 V (short-circuit comparator
threshold) and overtemperature is detected.
The OUTx is switched off if the voltage at OCMx is
higher than 4.6 V (overcurrent detection level) and over-
temperature is detected. The OCM voltage monitors the
output current at OUTx via the current ratio of 0.1. The
overcurrent-detection level of OUTx can be varied by
changing the OCMx resistor. If OUTx is switched off by
overtemperature and overcurrent detection, the CLLx
output remains logic low (overcurrent).
As the IC is only overtemperature-protected for short-cir-
cuit conditions at RETURNx or OUTx, it has to be
checked in each application that the chip temperature
does not exceed T

= 150
°
C in normal operation.
Test Hint
The overtemperature signal can be activated by connect-
ing ENABLE1 or ENABLE2 to 9 V/ 10 mA.

Note:
A good thermal resistance junction ambient (R

nection nearby a metal component (see description of GND-pins).
