7. Short Circuit Protection

A short circuit can occur for many reasons , a short on the load, a mistake during the connection of the wires between the device and

the load, an accidental short between the wires and so on. The outputs are not protected against the short circuit and if a short

occurs, the big amount of current flowing through the outputs can destroy the device. To avoid this risk can be useful to add a circuitry

to protect the device. FAN8705 have two types of short circuit protection, output to output short and output to ground short.

8. Thermal Shutdown

Thermal Shutdown Circuit turns OFF all outputs when the junction temperature typically reaches 175°C. It is intended to protect the

device from failures due to excessive junction temperature.

The Thermal Shutdown has the hysteresis of 25°C approximately.
