IFX1021SJ

Overview

The IFX1021SJ is a full-duplex LINbus transceiver manufactured by Infineon Technologies. It integrates one driver and one receiver within an 8-lead PG-DSO package. The device operates on a supply voltage ranging from 7V to 27V, supporting data rates up to 20kBd. It features a receiver hysteresis of 300 mV to enhance noise immunity. The component is rated for an operating temperature range of -40°C to 150°C and complies with MSL level 3 standards.

Feature Summary

Supports full-duplex communication over the LINbus protocol
Integrated protection against short circuits and reverse battery conditions
High noise immunity provided by specified receiver hysteresis

Applications

Automotive body electronics modules
LINbus sensor and actuator nodes
Vehicle comfort systems requiring robust serial communication

Procurement Notes

Verify component authenticity through authorized channels as this part is obsolete. Confirm that replacement candidates match the original electrical specifications and pinout compatibility. Check current availability status of substitute parts to ensure supply chain continuity for existing designs.

Selection Notes

Select this component for legacy automotive designs requiring a dedicated LINbus interface. Ensure the system power supply remains within the 7V to 27V operational window. Verify that the thermal environment stays within the -40°C to 150°C range to maintain reliable performance.

Part Context

This transceiver belongs to the IFX1021 family of LINbus interface devices. It serves as a physical layer solution for local interconnect networks in automotive applications. The device facilitates communication between microcontrollers and peripheral nodes.

Replacement Considerations

Public confirmed substitutes include MAX13021ASA/V+T and MCP2003A-E/SN. Evaluate these alternatives for pin compatibility and electrical parameter alignment before implementation.
