Infineon TLE94613ESV33XUMA1: A Comprehensive Technical Overview
The Infineon TLE94613ESV33XUMA1 represents a highly integrated, monolithic System Basis Chip (SBC) meticulously engineered for sophisticated automotive body control modules and other power-centric applications. This device exemplifies the trend towards greater functional integration, reducing system complexity, board space, and overall cost while enhancing reliability.
Core Architecture and Power Management
At its heart, the TLE94613ESV33XUMA1 features a highly efficient primary voltage regulator pre-configured to deliver a stable 3.3V output, capable of supplying microcontrollers and other logic circuits. This is complemented by a suite of low-dropout (LDO) linear regulators providing additional, well-regulated voltage rails for peripherals and sensors. A critical component of its power management system is the integrated high-speed CAN FD (Flexible Data-Rate) transceiver, which supports data rates up to 5 Mbit/s in the data phase, enabling fast and robust network communication essential for modern vehicle networks. It is fully compliant with the ISO 11898-2:2016 standard.
Advanced System Control and Monitoring
The device is designed for resilience and safety. It incorporates a windowed watchdog timer and a fail-safe output to ensure microcontroller supervision and initiate safe states in the event of a software hang or hardware fault. Furthermore, it boasts a comprehensive set of protection features, including over-voltage, under-voltage, and over-temperature protection, safeguarding both the SBC itself and the broader system from potential damage.
Interface and Control Capabilities
Beyond power and communication, the TLE94613ESV33XUMA1 offers significant interface flexibility. It includes six high-side drivers, which can be directly controlled via a Serial Peripheral Interface (SPI), allowing for precise control of loads like LEDs, relays, or lamps. This SPI interface also provides detailed diagnostic feedback on the status of outputs and internal registers, enabling advanced system health monitoring.
Target Applications
This SBC is predominantly targeted at the automotive market, finding its place in a wide array of applications:
Body Control Modules (BCMs)
Door control units
Seat control units
