The device provides embedded protective functions. Integrated protection functions are designed to prevent IC
destruction under fault conditions described in this data sheet. Fault conditions are considered as “outside” normal
operating range. Protection functions are not designed for continuous repetitive operation.
6.1
The SPIDER - TLE 7240SL is protected in case of over load or short circuit of the load. After time t
over loaded channel n switches off and the according diagnosis flag Dn is set.The channel can be switched on
after clearing the diagnosis flag. Please refer to
Figure 7
The current sink to ground ensures that the channels switch off in case of open input pin. The zener diode protects
the input circuit against ESD pulses. After power-on reset, the device enters idle mode.
6.2
A temperature sensor for each channel causes an overheated channel n to switch off to prevent destruction and
the according diagnosis flag Dn is set. The channel can be switched on after clearing the diagnosis flag. Please
refer to
6.3
In case of reverse polarity, the intrinsic body diode of the power transistor causes power dissipation. The reverse
current through the intrinsic body diode of the power transistor has to be limited by the connected load. The
and
protection is not active during reverse polarity.
