Infineon Technologies TLE8262EXUMA3

Overview

TLE8262EXUMA3 from Infineon Technologies is a high-speed CAN transceiver IC compliant with ISO 11898-2:2016, supporting data rates up to 5 Mbps, operating from 4.5 V to 27 V supply, and featuring integrated wake-up via bus activity detection. It is used in automotive body control modules for reliable communication between ECUs in harsh environments.

For engineers reviewing the TLE8262EXUMA3 datasheet, TLE8262EXUMA3 pinout, TLE8262EXUMA3 application, or TLE8262EXUMA3 equivalent, key selection criteria include bus fault protection level (±70 V), common-mode voltage range (−2 V to +14 V), low-power standby current (≤15 µA), and compatibility with 3.3 V or 5 V microcontroller I/O interfaces.

Technical Context

The TLE8262EXUMA3 implements a differential driver/receiver pair with dominant timeout protection, thermal shutdown, and TXD-controlled silent mode. Its RXD output is slew-rate controlled and compatible with both 3.3 V and 5 V logic families.

It integrates a VIO supply pin for independent I/O voltage reference, supports bus wake-up without host intervention, and features a fail-safe architecture where RXD goes recessive during supply undervoltage or bus fault conditions.

FAQ

What is the maximum allowable common-mode voltage for TLE8262EXUMA3?

The TLE8262EXUMA3 supports a common-mode voltage range of −2 V to +14 V per ISO 11898-2:2016. This ensures reliable operation during ground offset events caused by high-current loads like motors or solenoids, and provides immunity against typical automotive EMI coupling onto the CAN bus pair.

Does TLE8262EXUMA3 require an external bus termination resistor?

Yes, the TLE8262EXUMA3 does not integrate bus termination resistors. A 120 Ω resistor must be placed across CANH and CANL at each end of the bus segment to prevent signal reflections and ensure signal integrity at data rates up to 5 Mbps.

Can TLE8262EXUMA3 operate with a 3.3 V microcontroller without level shifting?

Yes - the dedicated VIO pin accepts 3.0 V to 5.5 V, allowing direct connection to 3.3 V MCU I/O. TXD and RXD are fully compatible with 3.3 V CMOS logic thresholds, eliminating need for external level translators in mixed-voltage designs.

How does the wake-up functionality work in standby mode?

In standby mode (STB = high), the TLE8262EXUMA3 monitors bus activity. When dominant or recessive transitions occur on CANH/CANL, the open-drain WAKE pin is pulled low within 1 µs, signaling the host MCU to exit low-power state and resume communication - all without CPU polling or external components.
