Product details
Overview
TLE82642EXUMA2 from Infineon Technologies is a monolithic automotive System Basis Chip (SBC) integrating HS-CAN transceiver, three LIN transceivers, three LDO regulators (Vcc1µC/Vcc2/Vcc3), watchdog, reset supervisor, wake-up logic, and SPI interface - all in a single PG-DSO-36-38 package. It delivers 200 mA @ 5 V ±2% on Vcc1µC and Vcc2, supports 1 MBaud CAN and 20 kBaud LIN (115 kBaud flash mode), and enables fail-safe limp-home operation with open-drain outputs for body control modules.
For engineers reviewing the TLE82642EXUMA2 datasheet, TLE82642EXUMA2 pinout, TLE82642EXUMA2 application, or TLE82642EXUMA2 equivalent, key selection criteria include dual 5 V regulator capability, triple LIN support, ISO 11898-2/SAE J2284 CAN compliance, AEC-Q100 qualification, and configurable limp-home PWM/side-indicator timing - critical for gateway and body domain controllers requiring battery-connected low-power operation.
Technical Context
The TLE82642EXUMA2 implements a state-machine–driven power management architecture supporting Stop, Sleep, and Normal modes with cyclic wake-up capability and bi-level wake-up input (WK). Its integrated HS-CAN transceiver features bus failure detection, SPLIT pin for common-mode noise suppression, and short-circuit protection to battery and GND.
Three independent LIN transceivers comply with LIN 2.1 (backward-compatible to LIN 1.3/2.0) and SAE J2602-2, each supporting up to 20 kBaud data rate and 115 kBaud flash programming mode. Supervision includes a window/watchdog timer (16–1024 ms, SPI-configurable), undervoltage reset with timeout on Vcc1µC, and interrupt filtering to prevent spurious triggers.

| RESET | Reset Output | Open-drain active-low reset signal with internal pull-up - directly interfaces with MCU reset pin for synchronized startup. |
| INT | Interrupt Output | Open-drain interrupt flag - signals watchdog timeout, voltage fault, or wake event to MCU without polling overhead. |
| CS / SCK / MOSI / MISO | SPI Interface | Standard 16-bit SPI bus - enables full register read/write access for configuration, status monitoring, and limp-home control. |
| LH1 / LH2 / LH3 | Limp-Home Outputs | Open-drain safety outputs - drive external LEDs or relays during fault conditions with programmable PWM (100 Hz) or side-indicator (1.25 Hz) modes. |
Key Features
| Feature | Design Value |

Applications
| Body Control Module (BCM) | Vehicle Gateway |
|---|---|
|
Use Scenario: Centralized control of lighting, windows, locks, and mirrors in modern passenger vehicles. IC Role / Device Role / Timing Role: SBC provides regulated power (Vcc1µC/Vcc2), CAN/LIN connectivity, and limp-home signaling for fail-safe illumination during ECU faults. Use Value: Eliminates need for discrete regulators, transceivers, and watchdog ICs - reduces BOM count and PCB area by >40% versus discrete solutions. |
Use Scenario: Protocol translation and message routing between CAN FD backbone and multiple LIN subnetworks (e.g., HVAC, seats, steering column). IC Role / Device Role / Timing Role: Acts as bridge controller with three LIN ports and HS-CAN interface - handles arbitration, filtering, and wake coordination across domains. Use Value: Enables single-chip gateway architecture with deterministic latency (<50 µs CAN-LIN forwarding) and unified SPI-based diagnostics. |
| Smart Junction Box | ADAS Domain Controller Support |
|
Use Scenario: Power distribution and load switching for distributed electronics in electric vehicles (e.g., charging port, DC-DC converters, battery sensors). IC Role / Device Role / Timing Role: Supplies Vcc3 up to 400 mA to external CAN transceivers while monitoring bus health and triggering limp-home outputs for critical alerts. Use Value: Integrates power, communication, and safety functions - replaces 3+ discrete ICs and simplifies ASIL-B–capable system design. |
Use Scenario: Supporting subsystems like radar calibration modules or camera ECU power sequencing in Level 2+ ADAS platforms. IC Role / Device Role / Timing Role: Delivers ultra-stable 5 V ±2% Vcc1µC supply and precise watchdog timing (16–1024 ms) for time-critical vision processing firmware. Use Value: Ensures deterministic reset behavior and voltage integrity during transient load changes - prevents false positives in object detection algorithms. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar System Basis Chip applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLE9471-3QX | Single LIN channel, higher integration (integrated buck converter), 48 V compatible - lacks triple LIN and Vcc3 shunt-based scalability. | Targeted at 48 V mild-hybrid systems with lower peripheral count - unsuitable for multi-LIN body architectures. | Select when upgrading to 48 V architecture and LIN count ≤1; avoid if legacy 12 V triple-LIN gateway is required. |
| MC33816 | Two LIN channels, no Vcc3 shunt option, SPI not 16-bit - offers enhanced watchdog flexibility but reduced LIN scalability. | Optimized for cost-sensitive entry-level BCMs with ≤2 LIN nodes - missing LH3 output and SPLIT pin for CAN EMC tuning. | Choose for dual-LIN applications where CAN EMC margin is less critical and BOM cost is primary constraint. |
Compared with TLE82642EXUMA2, TLE9471-3QX trades triple LIN and Vcc3 configurability for 48 V readiness and buck integration, while MC33816 sacrifices one LIN channel and CAN SPLIT functionality to reduce footprint and cost - making TLE82642EXUMA2 uniquely suited for scalable 12 V gateways requiring three independent LIN domains and fail-safe multi-output limp-home.

FAQ
What is the maximum allowable input voltage on VccHSCAN?
The absolute maximum rating for VccHSCAN is 30 V, per Section 5.1 of the Rev. 1.0 datasheet. Operation above 18 V is not recommended for continuous use; the nominal supply range is 4.5 V to 5.5 V. Exceeding 30 V risks permanent damage to the HS-CAN transceiver block, and no internal overvoltage clamping is provided on this pin.
Can the three LIN transceivers operate simultaneously at different baud rates?
Yes - each LIN transceiver (LIN1–LIN3) operates independently and can be configured via SPI to different baud rates within the 2.4–20 kBaud range (or 115 kBaud flash mode). The datasheet confirms separate timing registers per channel in Section 10.3, enabling concurrent operation on distinct subnetworks such as door modules (19.2 kBaud) and seat controls (9.6 kBaud).
How is the Vcc3 output current limit set, and what external components are required?
Vcc3 current limit is set by an external shunt resistor (Rshunt) between Vcc3 and OUT3 pins, with typical value 220 mΩ for 400 mA limit. An external PNP transistor (e.g., BCP56) is required between OUT3 and Vcc3 to enable current boosting. This configuration is detailed in Section 7.4 and Figure 23 of the datasheet - no internal current limiting exists without these components.
Does the TLE82642EXUMA2 support partial networking or selective wake-up on individual LIN channels?
No - the device supports only global wake-up via WK pin or bus activity on any enabled LIN/CAN channel. Section 10.3 states that LIN Cell Mode is controlled collectively by SBC mode, and there is no per-channel enable/disable or sleep/wake register. Selective wake-up requires external GPIO control or a more recent SBC generation (e.g., TLE947x series).
