TCA305GXLLA1

Overview

The TCA305GXLLA1 is a bipolar IC designed for inductive proximity switches, operating within a supply voltage range of 5 V to 30 V. It features an open-loop current consumption (IS) of less than 1 mA and supports switching frequencies up to 5 kHz without external integration capacitors. The device provides short-circuit proof outputs and includes internal stabilization that disables outputs when the supply voltage falls below approximately 4.5 V. It operates reliably across an ambient temperature range of -25 °C to 85 °C.

Feature Summary

• Lower open-loop current consumption and output saturation voltage
• Constant switching hysteresis regardless of temperature or supply voltage variations
• Internal oscillator stabilization with automatic output enable/disable logic
• Temporarily short-circuit proof outputs

Applications

• Inductive proximity switch design
• Automotive sensor systems
• Industrial automation monitoring

Procurement Notes

Verify the specific ordering suffix against official Infineon documentation to confirm package type and compliance status. Ensure the component matches the required PG-DSO-8-1 form factor. Confirm RoHS compliance and lead-free plating specifications prior to procurement to meet environmental standards.

Selection Notes

Select this component for applications requiring lower power consumption and stable hysteresis. Consider the TCA355 variant if a smaller PG-DSO-8-1 package is preferred over the standard DIP options. Evaluate the need for external integrating capacitors based on required noise immunity levels.

Part Context

This part belongs to the TCA 305/355 family of bipolar ICs developed from the TCA 205 series. These devices integrate all necessary functions for designing inductive proximity switches, including oscillator circuits and output stages, eliminating the need for external discrete components in basic configurations.

Replacement Considerations

The TCA355G serves as a pin-compatible alternative offering the same functionality in a PG-DSO-8-1 SMD package.
