TPS2661

SLVSFE3C – NOVEMBER 2020 – REVISED DECEMBER 2021

TPS2661x: 50-V, Universal 4–20 mA, ±20-mA Current Loop Protector With

Input and Output Miswiring Protection

universal input protection for ±20 mA, 0 mA to 20 mA,

1 Features

and 4 mA–20 mA. Low R_ONvalues 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.

•

±50-V operating voltage, ±55-V absolute maximum

Integrated fixed bipolar 32-mA current limit

Allows 2x current limit at start-up

50% space savings compared to a typical discrete

protection circuit

•

Low R-on: 7.5-Ω typical

Low I_Q(< 100 nA) – current drawn from loop when

powered from external supply

Protection against miswiring conditions on IN and

OUT

Protection during signal line surge IEC61000-4-5

(with external TVS)

Criteria-A EFT (IEC61000-4-4) immunity (with

external TVS)

Supports loop testing without supply (TPS26610

only)

•

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.
