8.3.1 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 specifies 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 capacitance.

When the ILIM_ADJ pin is shorted to ground, the TIOS102(x) is configured to source or sink a minimum of 500 mA. In this mode, current fault indication is disabled. Output Disable and Auto Recovery feature is also disabled in this mode. The driver is disabled if the power dissipation in the device causes the junction temperature to reach T(SDN).
