Overtemperature shutdown

Overtemperature shutdown
It is very simple to achieve overtemperature shutdown using the DIS pin. This protection is
latched disabled. We need to recycle the VCC voltage to restart the device. A simple circuit
using NTC, which is mounted on the MOSFET/rectifier heat sink can be used as shown
below. During normal temperature conditions, the voltage at the DIS pin is set lower than 4.5
V. As the temperature of the power device increases, NTC resistance falls and voltage at
the DIS pin starts increasing. As the voltage reaches at 4.5 V, the device gets shut down and
latched.
