... FUNCTIONAL DESCRIPTION General The L9825 integrated circuit features 8 power low-side-driver outputs. Data is transmitted to the device using the Serial Peripheral Interface, SPI protocol. Outputs 1 and 2 can be controlled parallel or serial. The power outputs features voltage clamping function for flyback current recirculation and are protected against short cir- cuit to Vbat ...

... L9825 Fault condition 2) "open load" or "output short circuit to GND" : the output is switched off and the voltage at the output drops below the diagnostics threshold, because the load current is lower than the output diagnostic cur- rent source, the load is interrupted. The diagnostic bit is low. ...

... All outputs withstand testpulses without damage. The correct function of the circuit with the Test Pulses coupled to the outputs is verified during the characteriza- tion for the typical application with R = 16W to 200W 600mH loads. The Test Pulses are coupled to the outputs with 200pF series capacitor. L9825 9/11 ...
