Description
General part information
TPS26611 Series
The TPS2661x is a compact, feature-rich, fully integrated current loop protector suitable for analog inputs, analog outputs, sensor transmitters, HART inputs, and UART IO protection. The device provides universal input protection for ±20 mA, 0 mA to 20 mA, and 4 mA–20 mA. Low RONvalues of 7.5 Ω 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 ±50 V. The MODE pin allows flexibility to enable 2x current limit through the device to enable proper start-up of two wire transmitters. Device is capable of operating from an external bipolar supply as low as ± 2.25 V to ±20 V. The device can also be powered from unipolar supplies as low as 3 V to 30 V. The TPS26610 and TPS26613 feature loop power mode to facilitate loop testing in un-powered state without ±Vs supplies.
The device also protects the system from output side miswiring in analog outputs and sensor transmitters by turning off the current path. The internal robust protection control blocks along with the 50-V rating of the TPS2661x help to protect against surge (IEC61000-4-5) and EFT (IEC61000-4-4) transients for signal lines. The device greatly reduces system footprint by its 2.9-mm × 1.6-mm 8-pin SOT-23 package.
