9.2.2.2 Driving Capacitive Loads
These devices are capable of driving capacitive loads on the OUT output. Assuming a pure capacitive load without series/parallel resistance, the maximum capacitance that can be charged without triggering current fault can be calculated as:
To drive higher capacitive loads and avoid overcurrent condition disabling the driver, it is recommended to leave ILIM_ADJ pin floating. With ILIM_ADJ floating, TIOS102(x) indicates overcurrent fault without blanking time delay (tSC) but does not disable the driver. Another approach is to drive high capacitive loads with a series resistor between the output and the load to avoid overcurrent condition. Capacitive loads can be connected to GND or VCC
