Notes
1. Stresses above the ones listed here may cause permanent damage to the device. Exposure to absolute
maximum rating conditions for extended periods may affect device reliability.
2. Integrated protection functions are designed to prevent IC destruction under fault conditions described in the
data sheet. Fault conditions are considered as “outside” normal operating range. Protection functions are not
designed for continuous repetitive operation.

Functional Description
5.3.2
Protection by Over Temperature Shutdown
The internal logic permanently monitors the junction temperature of the output stage. In the event of an over
temperature (Tj > Tjt) the output will immediately switch OFF with a latching behavior, see Chapter 5.3.3 for
details.
5.3.3
Infineon® INTELLIGENT LATCH
The BTS50060-1TEA provides Infineon® INTELLIGENT LATCH to avoid permanent resetting of a protective,
latched switch OFF caused by over current shutdown or over temperature shutdown) in PWM applications. To
reset a latched protective switch OFF the fault has to be acknowledged by commanding the input LOW for a
minimum duration of treset. See Figure 15 for details.

Reverse Polarity Protection
Reverse polarity condition is the mix-up of the power supply connections of the entire application. This means,
application GND connector is connected to positive supply voltage, while Vs pin is connected to negative supply
voltage or ground potential. See Figure 16 and Figure 53.
