Product details
Overview
TLE82642EXUMA1 from Infineon Technologies is a high-integration CAN FD transceiver with integrated voltage regulator (5 V, 150 mA), bus wake-up capability, and ±70 V bus fault protection. It operates from 4.5 V to 27 V supply, supports data rates up to 5 Mbit/s, and features low-power standby mode with current consumption of 15 µA. It is used in automotive body control modules for robust communication between ECUs under harsh electrical conditions.
For engineers reviewing the TLE82642EXUMA1 datasheet, TLE82642EXUMA1 pinout, TLE82642EXUMA1 application, or TLE82642EXUMA1 equivalent, key selection criteria include bus fault tolerance, integrated LDO output capability, CAN FD timing compliance, and wake-up sensitivity in battery-supplied nodes.
Technical Context
The TLE82642EXUMA1 implements ISO 11898-2:2016-compliant physical layer signaling with symmetric differential bus drive and receiver hysteresis of 150 mV. Its integrated 5 V/150 mA LDO eliminates need for external regulators in ECU power tree design.
Wake-up functionality responds to dominant bus pulses ≥ 150 ns with < 10 µA quiescent current in Standby mode. The device supports split termination via dedicated Rs pin and includes TXD slew-rate control for EMI optimization.

Equivalent & Alternatives
The following parts are listed as comparable options for similar CAN FD transceiver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| NXP TJA1044T/3 | No integrated LDO; requires external 5 V supply; lower bus fault rating (±65 V) | Requires additional regulator IC and decoupling; less suitable for space-constrained modules | Select when LDO integration is unnecessary and cost-per-node is prioritized over board area |
| ST TJA1043TK | Supports only classical CAN (1 Mbit/s); no CAN FD; 5 V LDO rated at 80 mA | Not usable in FD-based architectures requiring >1 Mbit/s data phase | Select only for legacy CAN networks where FD bandwidth and higher LDO current are not required |
Compared with TJA1044T/3 and TJA1043TK, the TLE82642EXUMA1 uniquely combines CAN FD speed, ±70 V fault tolerance, and 150 mA LDO in one DSO-36 package-enabling compact, future-proof body electronics designs without external regulation or derating.

FAQ
What is the maximum data rate supported by the TLE82642EXUMA1?
The TLE82642EXUMA1 supports CAN FD with data phase rates up to 5 Mbit/s, compliant with ISO 11898-2:2016. It maintains full signal integrity and timing margin at 2 Mbit/s over 10 m of twisted-pair wiring, making it suitable for high-throughput body domain controllers requiring fast firmware updates and diagnostics.
Does the TLE82642EXUMA1 require an external voltage regulator?
No. The device integrates a 5 V ±3% LDO capable of delivering 150 mA, sufficient to power typical 32-bit automotive MCUs and associated peripherals. An external 10 µF ceramic capacitor on VOUT is mandatory for stability, but no additional regulator IC is needed in standard implementations.
How does the wake-up function operate in standby mode?
In standby mode (STB = HIGH), the TLE82642EXUMA1 monitors the CAN bus for dominant pulses ≥150 ns duration. Upon detection, WAKE pin goes low, signaling the MCU to exit low-power state. Bus activity is sampled continuously with <10 µA added current, ensuring zero-latency wake-up without polling overhead.
Can the TLE82642EXUMA1 be used in 24 V commercial vehicle systems?
Yes. Its 4.5 V to 27 V operating range covers both 12 V passenger car and 24 V truck/bus systems. The ±70 V bus fault protection exceeds ISO 16750-2 requirements for commercial vehicles, and the LDO remains stable across this full input range without derating or external components.
