Texas Instruments TPS2661EVM Current Loop Protector EVM
Texas Instruments TPS2661EVM Current Loop Protector Evaluation Module (EVM) allows reference circuit evaluation of TPS26611 and TPS26612 current-loop protectors. The Texas Instruments TPS2661 product is a 50V, universal (±20mA, 0mA to 20mA, 4mA to 20mA) current-loop protector with integrated fixed bipolar 30mA current limit and output overvoltage protection. The product provides protection against miswiring conditions on input/output and offers robust signal line protection in industrial and process automation systems.Features
- Supports bidirectional current loops with 0V to ±50V operating range (with external VCC)
- Fixed ILIMIT = ±30mA ±15%
- Enable (EN) pin control
- Part status reporting through SGOODb pin
- Protection against input-side miswiring
