JAJSKF6C November 2020 – December 2021 TPS2661
PRODUCTION DATA
TPS26610 can be used for protection of current inputs in an Analog Input module as shown in Figure 9-1. The current signal is measured by ADC across Rburden. Bipolar current limit of ±32 mA ensures that the precision burden resistor as well as the ADC front end stays well protected against any unwanted voltages or currents caused due to faulty transmitter or miswiring. High Voltage rating of IN pin of TPS26610 ensures that it also protects the system from surge and EFT events as well. For reverse current blocking (OUT to IN), connect burden resistor to GND (SW1 = Closed) and used single supply (+Vs,GND) with TPS26610.
