Thermal Protection
The NIS5135 has an integrated temperature sensing circuit that protects the die in the event of over temperature. The trip point has been
intentionally set high at +175˚C to allow for increased trip times during high power transient events. The NIS5135 will shut down current flow to
the output when the die temperature reaches +175°C. The NIS5135MN1 will restart after the Enable pin has been toggled or the input power has
been cycled. The NIS5135MN2 will auto restart after the die temperature has been reduced by -45°C.
Even though the thermal trip point has been set high to allow for high current transients the circuit design should accomplish best thermal
performance with good thermal layout of the PCB. It is not recommended to operate NIS5135 above +150°C over extended periods of time.
