Infineon Technologies TLE62512GXUMA1

Overview

TLE62512GXUMA1 from Infineon is a high-speed CAN transceiver compliant with ISO 11898-5, supporting up to 1 MBaud data rate, featuring bus wake-up and local wake-up capability, integrated failure diagnosis via NERR output, split termination for recessive level stabilization, and separate VIO supply (1.8–5.5 V) for microcontroller interface compatibility.

For engineers reviewing the TLE62512GXUMA1 datasheet, TLE62512GXUMA1 pinout, TLE62512GXUMA1 application, or TLE62512GXUMA1 equivalent, this device is selected for automotive HS-CAN networks requiring low-power sleep mode (<15 µA), robust ESD protection (±9 kV IEC 61000-4-2), and comprehensive fault detection including TxD–RxD short, CANH/CANL short, dominant clamping, and under-voltage monitoring at VCC/VIO/VS.

Technical Context

The TLE62512GXUMA1 implements a differential physical layer driver/receiver pair with symmetrical CANH/CANL output stages optimized for low electromagnetic emission (EME) and high immunity to electromagnetic interference (EMI). Its internal mode control logic supports five operation modes - Normal, Receive-Only, Stand-By, Go-To-Sleep, and Sleep - each governed by EN, NSTB, and WK inputs.

Failure diagnostics are hardware-asserted through dedicated outputs: NERR (open-drain, active-low error flag) indicates bus faults (CANH/CANL short, dominant clamping), local faults (TxD timeout, RxD recessive clamp), and power faults (VCC/VIO/VS undervoltage); INH provides open-drain inhibit control of external circuitry; SPLIT supplies a stabilized 0.5×VCC reference for external split termination.

FAQ

What is the function of the SPLIT pin on the TLE62512GXUMA1?

The SPLIT pin provides a stable 0.5×VCC reference voltage used to bias external split termination resistors (typically two 60 Ω resistors between CANH/CANL and SPLIT). This configuration improves recessive bus voltage stability, reduces common-mode noise, and enhances EMC performance in long or branched CAN networks - a requirement for robust automotive implementations per OEM specifications.

How does the TLE62512GXUMA1 handle bus failure detection?

The device detects 11 distinct fault conditions in hardware, including CANH/CANL short to battery or ground, TxD-to-RxD short, RxD permanent recessive clamping, bus dominant clamping, and under-voltage events on VCC, VIO, and VS. All are reported synchronously via the open-drain NERR pin, enabling immediate MCU response without software polling or timing-critical interrupt servicing.

Can the TLE62512GXUMA1 operate with a 3.3 V microcontroller while powered from a 5 V supply?

Yes. The TLE62512GXUMA1 features a dedicated VIO pin (1.8–5.5 V range) that independently powers the TxD, RxD, EN, NERR, and NSTB logic interfaces. With VCC = 5 V and VIO = 3.3 V, the transceiver fully supports 3.3 V MCU signaling while maintaining full 5 V analog/driver stage performance and fault detection integrity.

Is the TLE62512GXUMA1 pin-compatible with earlier Infineon CAN transceivers?

Yes. The TLE62512GXUMA1 is fully pin-compatible and function-compatible with the TLE6251G, allowing drop-in replacement in existing designs. Both share identical PG-DSO-14 footprint, pin assignment, electrical characteristics, and functional behavior - including Sleep mode current, wake-up sources, and failure diagnosis logic - simplifying migration and second-source validation.
