TCA355GXLLA1

Overview

The TCA355GXLLA1 is a bipolar IC designed for inductive proximity switches, housed in an 8-pin PG-DSO-1 package. It operates within a supply voltage range of 5 V to 30 V and supports ambient temperatures from -25 °C to 85 °C. The device features lower open-loop current consumption (IS < 1 mA) and lower output saturation voltage compared to predecessors. It provides constant switching hysteresis regardless of temperature or supply voltage variations. The outputs are temporarily short-circuit proof and enable automatically once the oscillator stabilizes at VS ≥ 5 V.

Feature Summary

• Lower open-loop current consumption and reduced output saturation voltage
• Constant switching hysteresis independent of temperature and supply voltage
• Temporarily short-circuit proof outputs with automatic enable upon oscillator stabilization

Applications

• Inductive proximity switch design
• Metal plate detection systems
• Resonant circuit damping applications

Procurement Notes

Verify component authenticity by checking markings against official Infineon datasheets. Confirm the package type matches the specified PG-DSO-8-1 format. Ensure environmental compliance documentation aligns with RoHS standards. Validate supplier authorization status before purchase.

Selection Notes

Select this component when designing inductive sensors requiring stable hysteresis across varying thermal conditions. Consider its low current consumption for battery-operated or energy-efficient applications. Verify that the operating voltage range meets system requirements between 5 V and 30 V.

Part Context

This part belongs to the TCA 305/355 family of bipolar ICs developed from the TCA 205 series. It integrates all necessary functions for inductive proximity switch designs, including oscillator and logic outputs. The TCA 355 variant specifically utilizes surface-mount packaging for compact integration.

Replacement Considerations

The TCA 305 G serves as a functional alternative within the same family, offering similar capabilities in a different package configuration.
