8.3.2 Current Limit Configuration

The output current can be configured with an external resistor on ILIM_ADJ pin. The highest current limit setting with an external resistor of 10 kΩ provides a minimum of 300 mA over the operating temperature and voltage range.

Output disable due to current fault and current fault auto recovery features can be disabled by floating ILIM_ADJ pin. However, the current fault indication is still active in this configuration. This feature is useful when driving large capacitances.

When ILIM_ADJ pin is shorted to ground, the TIOL112(x) is configured to be in the IO-link master mode. In this mode, the TIOL112(x) can source or sink minimum of 500 mA to generate a wake-up request. In addition, the TIOL112(x) enables a small current sink of 5 mA (minimum). The current fault indication, output disable, and auto recovery features are disabled in this mode.
