Infineon TLE94713ESXUMA1: A Comprehensive System Basis Chip for Automotive Applications

The increasing complexity of modern automotive electronic control units (ECUs) demands highly integrated and robust power management solutions. Addressing this need, Infineon Technologies has developed the TLE94713ESXUMA1, a state-of-the-art System Basis Chip (SBC) that combines multiple critical functions into a single, compact package. This device is engineered to serve as the central power and communication hub for a wide range of automotive applications, particularly in body control modules, gateways, and sensor integration.

At its core, the TLE94713ESXUMA1 is built for exceptional reliability and performance in harsh automotive environments. It features a primary voltage regulator that supplies the microcontroller and other ICs, alongside a fully independent low-power mode (LPM) controller. This LPM is crucial for modern vehicles, enabling key comfort features like wake-up on remote key entry while maintaining ultra-low quiescent current to prevent battery drain during extended parking periods.

A standout feature of this SBC is its integrated high-speed CAN FD (Flexible Data-Rate) transceiver. Supporting data rates up to 5 Mbit/s, it ensures robust and high-bandwidth communication within the vehicle network, which is essential for handling the vast amounts of data required by advanced driver-assistance systems (ADAS) and other data-intensive functions. The transceiver is designed to be highly immune to electromagnetic interference (EMI) and boasts very low electromagnetic emission (EME), complying with stringent automotive OEM requirements.

Beyond communication, the chip integrates two high-side switches capable of driving loads such as LEDs or relays directly. More importantly, it includes a safety power supply for a microcontroller including a watchdog and a fail-safe output. This integrated safety architecture is vital for applications requiring functional safety, as it can monitor the microcontroller and initiate a controlled system reset or a safe state in case of a software freeze or failure, aligning with standards like ISO 26262.

The device is offered in a space-saving PG-DSO-28 package, making it suitable for space-constrained ECU designs. Its operational junction temperature range of -40°C to 150°C ensures full functionality under the hood in all climate conditions, from frigid cold starts to scorching summer heat.

ICGOODFIND: The Infineon TLE94713ESXUMA1 stands out as a premier all-in-one power and communication solution for next-generation automotive ECUs. Its deep integration of voltage regulation, network communication, power switching, and critical safety features into a single chip significantly reduces system complexity, board space, and overall bill-of-materials costs. For designers aiming to build reliable, efficient, and feature-rich automotive electronic systems, this SBC represents a superior and highly competitive foundation.
