Order now


The TPS2661EVM allows reference circuit evaluation of TPS26611 and TPS26612 current-loop protectors. The TPS2661 product is a 50-V, universal (±20-mA, 0-mA to 20-mA, 4-mA to 20-mA) current-loop protector with integrated fixed bipolar 30-mA 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.

  • Supports bidirectional current loops with 0-V to ± 50-V operating range (with external VCC)
  • Fixed ILIMIT = ±30 mA ±15%
  • Enable (EN) pin control
  • Part status reporting through SGOODb pin
  • Protection against input-side miswiring
