... The device provides many diagnostics of the load enabling both open load and short circuit detection. The SPI diagnostic bits indicate any eventual latched fault condition. Each output stage is protected against short circuit. In case of over load, the affected channel switches off. Temperature sensors are available for each channel in order to protect the device against over temperature. ...
