JAJSJD1D February 2022 – March 2023 TIOL112 , TIOL1123 , TIOL1125
PRODUCTION DATA
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.
ILIM_ADJ Pin Condition | CQ Current Limit (Min.) | NFAULT Indication During Current Fault | Output Disable and Auto Recovery |
---|---|---|---|
RSET resistor to L- (10 kΩ to 110 kΩ) | Variable (35 mA to 300 mA) | Yes | Yes |
Connected to L- (RSET 0 to 5 kΩ) | 500 mA | No | No |
OPEN | 260 mA | Yes | No |
