TCA505BG

Sensor And Detector Interfaces Overview

The TCA505BG is a bipolar monolithic IC designed for inductive proximity switches, featuring an integrated oscillator, demodulator, and threshold switch. It operates within a supply voltage range of 4 V to 40 V (or 3.1 V to 4.5 V when VREF is connected to VS). The device includes two antiphase output stages capable of up to 60 mA, with short-circuit and overload protection. Current consumption is less than 0.8 mA. It supports switching frequencies up to 5 kHz and functions across a temperature range of -40 °C to 110 °C.
