The TIOL1115 EVM provides users with the ability to evaluate TI's TIOL111x family of IO-Link transceivers. The EVM includes the TIOL1115 which provides full IO-Link functionality and an on-chip 5-V LDO. With pin- to-pin compatibility throughout the TIOL111 family, the EVM can also support the TIOL111 (no LDO) or the TIOL1113 (3.3-V LDO). The EVM includes the ability to measure and monitor numerous signals including L+, L-, CQ, TX, RX, and more while also being able to adjust the device output current via an on-board potentiometer. Although the TIOL111 family of devices include on-chip ESD (IEC61000-4-2) and surge protection, which eliminates or reduces the size of any TVS diodes, pads for these diodes are included for modification to meet users' requirements.
