TLE8250G Overview
A CAN transceiver is a network interface IC within the broader communications-semiconductor hierarchy. It converts logic-level TXD and RXD signals into the differential CANH and CANL bus signals, then converts received bus levels back into a controller-compatible RXD signal. High-speed CAN is a two-wire differential network designed for robust, priority-based communication between electronic control units, where common-mode rejection and disturbance tolerance are central to reliable operation.
The TLE8250G combines a 1 Mbit/s-capable CAN driver with a receiver interface and bus protection functions. Its symmetric CANH and CANL behavior supports low EMI in applications where electronic modules must coexist on a shared harness. The device supports partially supplied networks, an important characteristic for automotive systems where some nodes can be unpowered while others remain active. In power-down mode, receiver input resistors are switched off so the transceiver input becomes highly resistive, reducing unwanted loading of an inactive bus.
Infineon Smart Power Technology combines bipolar and CMOS control circuitry with DMOS power devices on one monolithic circuit. The manufacturer describes this technology as supporting high ESD robustness and high electromagnetic immunity. The TLE8250G and its Smart Power Technology are stated to be AEC qualified. The transceiver also meets or exceeds ISO 11898-2 requirements and is offered in a RoHS-compliant PG-DSO-8 package, making it appropriate for electronic control units, body modules, gateways, sensors, and industrial automation interfaces.
Use the TLE8250G when the PCB already expects an eight-pin PG-DSO-8 CAN interface and the bus operates at or below 1 Mbit/s. Designers should confirm the transceiver I/O voltage against their controller, preserve the CAN bus termination network, and follow the manufacturer’s layout guidance to minimize radiated emissions. Because only verified electrical limits, supply ranges, temperature ranges, and pin-level details are not included in the supplied search data, those values require confirmation in the manufacturer datasheet before release to production.
The TLE8250G is also fully pin- and function-compatible with its Infineon predecessor, the TLE6250G, according to the verified manufacturer documentation. This predecessor relationship provides a documented upgrade path, but design reviews should still compare operating voltages, timing, transient immunity, and lifecycle requirements for the exact production variant.

Typical Applications
TLE8250G is suitable for 6 applications: Automotive Body Control Module, Vehicle Gateway Module, Automotive Sensor Node, Industrial Automation Controller, Motor and Power-Control ECU, Distributed Diagnostic Interface.
Automotive Body Control Module
The TLE8250G fits an electronic control unit that connects a CAN controller to a two-wire vehicle harness. Its 1 Mbit/s capability covers the device’s high-speed CAN role, while the stated low emissions, high immunity, and robust ESD behavior help preserve communication reliability in electrically noisy environments. Smart Power Technology integrates CMOS control, bipolar circuitry, and DMOS power devices on one monolithic circuit. The eight-pin PG-DSO-8 package keeps the physical interface compact, and partial-network support is valuable when some modules on the harness are unpowered. Final production design must verify supply voltage, temperature, and exact pin limits from the Infineon datasheet.
Recommended
Vehicle Gateway Module
A gateway controller can use the TLE8250G to bridge its CAN protocol engine to a physical vehicle bus. The transceiver converts controller logic into differential CANH and CANL signals and returns received bus data through RXD. Its documented 1 Mbit/s rate suits high-speed CAN nodes, while low emissions-related interference is valuable when multiple communications domains share an enclosure or harness. The PG-DSO-8 package helps preserve PCB area, and high resistive power-down behavior reduces loading in partially supplied architectures. Engineers should still check signal timing and controller logic thresholds against the exact device operating range before layout release.
Recommended
Automotive Sensor Node
The TLE8250G is suitable for a remote CAN sensor node that must remain connected to a partially powered vehicle network. Its support for partially supplied networks and receiver-resistor shutdown provide a high-impedance state when the node enters power-down, reducing disruption to other active nodes. The one-driver, one-receiver arrangement and 1 Mbit/s speed support the standard high-speed CAN physical layer. Robust ESD protection and high electromagnetic immunity are especially relevant where sensor harnesses connect the module to external sensors. Layout must maintain a short, symmetric bus path and preserve the intended termination network to avoid reflections and excess radiated emissions.
Recommended
Industrial Automation Controller
The TLE8250G can interface an industrial automation controller with a high-speed CAN fieldbus segment at rates up to 1 Mbit/s. ISO 11898-2 compliance provides a defined high-speed CAN physical-layer basis, while high immunity and low emissions help operation near motors, relays, and switching equipment. The eight-pin PG-DSO-8 package supports compact controller boards, and partial-network support can simplify systems where some field devices start or shut down independently. For industrial deployment, validate the exact operating temperature, supply levels, bus fault thresholds, isolation strategy, and connector-level surge requirements before treating the interface as a complete industrial protection solution.
Recommended
Motor and Power-Control ECU
The TLE8250G fits communication logic in a motor-control or power-control electronic unit where switching events can couple noise into connected harnesses. Its manufacturer-stated high electromagnetic immunity and ESD robustness help the receiver and interface logic withstand automotive disturbances. The one-driver, one-receiver high-speed CAN interface provides connectivity up to 1 Mbit/s without occupying a large package footprint. Smart Power Technology is relevant because it combines controller circuitry with DMOS power devices in a monolithic implementation. Place the transceiver near the bus connector, keep CANH and CANL routing balanced, and follow the manufacturer grounding and termination guidance to minimize common-mode conversion.
Recommended
Distributed Diagnostic Interface
The TLE8250G is appropriate for a diagnostic or service interface that connects an embedded controller to a high-speed CAN network. Compliance with or exceedance of ISO 11898-2 and operation up to 1 Mbit/s align with established automotive CAN physical layers. The low-EMI design reduces interference in compact diagnostic modules, while ESD robustness supports connection to external harnesses and service connectors. The transceiver’s partially supplied-network behavior can be helpful where ignition or sleep states isolate modules unevenly. Designers should ensure the controller supports the selected CAN data rate, provide the prescribed termination only at appropriate bus locations, and confirm recessive and dominant timing margins from the manufacturer data sheet.

Design Notes
Route CANH and CANL as a tightly coupled differential pair with continuous return-path geometry, equalized lengths, and minimal stubs. Position the TLE8250G near the bus connector and follow the exact pin and grounding arrangement in the Infineon datasheet. Avoid placing switching-regulator loops, high-current motor returns, or crystal clocks beneath the bus pair, because those paths can increase common-mode conversion and radiated emissions.
Do not treat every node in a CAN network as an individual termination point. Use the bus termination scheme required by the selected network topology and verify that CANH and CANL receive their intended resistor network. Incorrect termination can create excessive reflections, while placing termination at every node can over-damp the bus. Also confirm that the controller logic thresholds and supply levels match the TLE8250G.
The TLE8250G is positioned as a low-emissions CAN interface, but package placement still determines practical EMI performance. Keep the bus pins away from antenna-like test pads and long unprotected traces, use a compact ground return, and observe the manufacturer’s recommended decoupling arrangement. Validate radiated and immunity performance at the module level because connector cables, chassis grounding, and neighboring converters can dominate system emissions.
In power-down mode, the TLE8250G switches off receiver input resistors so the transceiver input becomes high resistive. Use this behavior when planning partially supplied networks, but do not infer that every supply rail is removed; verify the exact device power-down and unpowered conditions in the datasheet. The TLE8250G is not itself an isolated CAN interface, so galvanic-isolation requirements must be handled separately when a module crosses large ground-potential differences.
Compliance Information
The verified Infineon documentation identifies a RoHS-compliant PG-DSO-8 package and states that the TLE8250G and Smart Power Technology are AEC qualified. No verified REACH, lead-free, halogen-free, or conflict-minerals statement was supplied.
