TLE8458GV33XUMA1

Drivers, Receivers, Transceivers Overview

The TLE8458GV33XUMA1 is an automotive LIN transceiver with an integrated 3.3 V low-drop voltage regulator, manufactured by Infineon Technologies. It operates within a supply voltage range of 7 V to 27 V and supports data transmission rates up to 20 kbps compliant with LIN 2.1 standards. The device features Normal Slope Mode for optimized electromagnetic compatibility and Software Flash Mode for microcontroller programming. It includes Stop and Sleep modes with quiescent currents as low as 40 µA and 12 µA respectively. The component is housed in a PG-DSO-8-16 package and functions across a junction temperature range of -40 °C to 150 °C.

Drivers, Receivers, Transceivers Feature Summary

• Integrates a 3.3 V LDO capable of delivering 50 mA output current for microcontroller power supply.
• Supports multiple operation modes including Normal Slope, Software Flash, Stop, and Sleep for flexible power management.
• Provides high electrostatic discharge robustness and protection against bus short circuits to ground and battery supply.
• Features local wake-up via the WK pin and remote wake-up via the LIN bus signal.

Drivers, Receivers, Transceivers Applications

• Automotive body electronics modules requiring LIN communication and local power regulation.
• Sensor and actuator nodes in distributed automotive networks.
• Electronic control units (ECUs) needing integrated power supply and interface capabilities.

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix XUMA1 to confirm tape-and-reel packaging configuration. Ensure the GV33 designation matches the required 3.3 V regulator output for your system design. Confirm that the component status aligns with your product lifecycle requirements, as availability may vary based on production schedules.

Drivers, Receivers, Transceivers Selection Notes

Select this variant when a 3.3 V regulated supply is required for the connected microcontroller. Compare with the TLE8458G variant if a 5 V regulator is needed instead. Consider the thermal resistance characteristics and package size constraints when designing the PCB layout for heat dissipation in enclosed automotive environments.

Drivers, Receivers, Transceivers Part Context

This component belongs to the TLE8458 family of LIN transceivers from Infineon. It shares functional similarities with other automotive interface ICs but distinguishes itself through the monolithic integration of the voltage regulator. This integration reduces external component count compared to using separate transceiver and LDO devices.

Drivers, Receivers, Transceivers Replacement Considerations

The datasheet notes pin and function compatibility with stand-alone LIN transceivers such as the TLE7259-3GE. However, direct replacement requires verifying that the target application can accommodate the integrated 3.3 V regulator output and does not require a different voltage level or separate regulator functionality.
