Current-Loop Protector
This user's guide describes the evaluation module (EVM) for the Texas instruments TPS2661x current-loop
protector. The document provides EVM configuration information and test setup details for evaluating the
TPS26610 and TPS26612 devices. The EVM schematic, board layout, and bill of materials (BOM) are also
included.
The TPS26611, TPS26613 and TPS26614 devices can also be evaluated on this EVM by replacing
the TPS26610 (U1) device.
