Selection Guide

Choose the TIOL1125 when you need an IO-Link device transceiver with a fixed 5-V LDO output, low residual voltage, and integrated surge protection. It is ideal for industrial sensors and actuators that require a regulated 5-V rail for external components. If you need a selectable 3.3-V/5-V LDO output, consider the TIOL1123L. For designs that do not require an integrated LDO, the TIOL1115 is a lower-cost option. Cross-brand alternatives like the MAX14827A may offer similar functionality but require careful pinout verification. The TIOL1125 is the best choice for new designs seeking a compact, feature-rich IO-Link interface with minimal external components.

Key Differentiators

  • Integrated 5-V LDO output (vs TIOL1115)
  • Low residual voltage of 0.5 V at 200 mA (vs MAX14827A)
  • Pin-compatible with TIOL111 family (vs MAX14827A)

Design Notes

The TIOL1125 integrates a 5-V LDO that can supply external components. Ensure the LDO output capacitor (typically 1 uF to 10 uF) is placed close to the VCC pin to maintain stability. The LDO input is tied to L+, so the supply voltage must be within 7 V to 36 V. For higher load currents, consider the power dissipation in the LDO and provide adequate thermal relief on the PCB.

For optimal EMC performance, place the TIOL1125 close to the IO-Link connector. Use a solid ground plane and minimize loop areas for the CQ line. The integrated surge protection reduces the need for external TVS diodes, but verify that the PCB layout provides a low-impedance path for surge currents to L-.

Do not exceed the absolute maximum ratings for L+ (36 V). Ensure the CQ line is properly terminated according to the IO-Link specification. The ILIM pin sets the current limit; leave it unconnected for default or connect a resistor to adjust. Verify the LDO output voltage matches your load requirements, as the TIOL1125 provides a fixed 5-V output.
