1 pcs : TPS26610DDFR - Hot Swap Voltage Controllers 50-V, universal 4-20-mA, +/-20-mA current loop protector 8-SOT-23-THIN -40 t

TPS2661x Current Loop Protector Texas Instruments TPS2661x Current Loop Protector is a compact, feature-rich, fully integrated current loop protector suitable for analog inputs, analog outputs, sensor transmitters, HART Inputs, and UART IO protection. It provides Universal Input protection for ±20mA, 0 to 20mA, and 4-20mA. A low RON of 7.5Ω minimizes drop in the current loop, thereby extending operating range and supporting operation even with lower voltage power supplies. The device can withstand and protect the loads from positive and negative supply voltages up to ±50V. The MODE pin allows flexibility to enable a 2x current limit through the device to enable the proper startup of two-wire transmitters. The device is capable of operating from an external bipolar supply as low as ± 2.25V to ±20V. It can also be powered from unipolar supplies as low as 3V to 30V. The Texas Instruments TPS2661x features loop power mode to facilitate loop testing in an un-powered state without ±Vs supplies.
