TLE7250GVIOXUMA2 - 1Mbps CAN Transceiver, 3.3/5V VIO | Infineon
Référence : TLE7250GVIOXUMA2 ✓ ActifTLE7250GVIOXUMA2 Présentation
A CAN transceiver (also called a CAN physical-layer interface) is the component that sits between a microcontroller's CAN protocol controller and the differential CANH/CANL bus wiring. It converts the digital TXD signal into a dominant/ recessive differential bus voltage, and converts the received bus levels into a clean RXD logic signal, while protecting the host controller from bus faults and external interference.
Key features of this device include a 1 Mbps maximum data rate for classic CAN, separate VIO supply pin for 3.3 V or 5 V microcontroller logic levels, 100 mV receiver hysteresis for noise immunity, half-duplex operation, a normal/standby operating mode for low-power parks, and MSL 2A moisture-sensitivity classification. The transceiver is specified for low bus emissions and high electromagnetic immunity, both of which are essential in automotive environments.
Internally the device combines a CAN bus driver stage, a comparator-based receiver with defined hysteresis, internal biasing, and bus-fault and ESD protection on CANH and CANL. The VIO domain decoupling the digital interface from the 5 V transceiver domain lets a 3.3 V MCU talk directly to the bus without level shifters, while the separate transceiver supply keeps bus-side biasing stable.
Typical applications include automotive body control units, electric-vehicle and powertrain CAN gateways, industrial PLC and robot controller CAN networks, elevator and building automation controllers, and sensor-hub CAN nodes in 3.3 V microcontroller systems.
When designing around this part, place the VIO decoupling capacitor directly at the VIO pin and treat CANH and CANL as a tightly coupled differential pair, keeping stub lengths short and the loop area minimal. Use the standby input to force a defined low-power state during wake-up sequences.
This page consolidates the device specification, drop-in alternatives within the Infineon CAN portfolio, comparison parameters, and practical design guidance so that designers can qualify the transceiver quickly instead of parsing multiple catalogue entries.

Applications typiques
TLE7250GVIOXUMA2 convient pour 6 applications: Automotive Body Control Module CAN Node, Electric Vehicle Powertrain CAN Gateway, Industrial PLC and Robotics CAN Network, Building Automation and Elevator Control, 3.3 V Microcontroller Sensor Hub Node, CAN-to-Serial Gateway and Test Equipment.
Automotive Body Control Module CAN Node
The TLE7250GVIOXUMA2 suits body control modules that sit on a 500 kbit/s to 1 Mbit/s vehicle CAN backbone. Its 1 Mbps ISO 11898-2 compliant data rate, low bus emissions and high electromagnetic immunity let the module coexist with cranking, alternator and body-actuator switching noise on the same harness. The 3.3 V or 5 V VIO pin means a modern 3.3 V automotive MCU drives TXD and reads RXD directly, while the transceiver domain still runs from a clean 5 V rail. In a standby-capable design the controller can park the bus during key-off and wake it in a defined state before other nodes start transmitting.
Recommandé
Electric Vehicle Powertrain CAN Gateway
Battery management, inverter and vehicle-controller subsystems often share a high-speed CAN backbone, and the TLE7250GVIOXUMA2 gives a compact, protected physical-layer interface for each of them. The 1/1 half-duplex topology suits the classic CAN segment used for powertrain coordination rather than CAN FD diagnostics links. The device's high immunity lets it operate on harnesses routed next to traction motors and contactors, while low emissions prevent the transceiver from disturbing neighbouring nodes. The 8-pin SOIC-8 footprint keeps the interface small enough for a densely packed inverter control board.
Recommandé
Industrial PLC and Robotics CAN Network
Factory automation cells frequently use CAN as the backbone between PLCs, robot controllers and sensor nodes, and the TLE7250GVIOXUMA2 covers that physical layer in a 1 Mbps segment. Because the transceiver accepts 3.3 V VIO, it can pair directly with 3.3 V industrial controllers and wireless-capable IO modules without level translators. The 100 mV receiver hysteresis rejects induced noise from nearby variable-frequency drives and contactors, and the normal/standby mode allows a robot cell to drop the bus to a low-power state during safe-stop cycles. Use the standby control input as part of the cell's safety chain.
Recommandé
Building Automation and Elevator Control
Lift and building-automation controllers talk to door units, call panels and ventilation equipment over CAN segments, and the TLE7250GVIOXUMA2 provides a rugged, compact interface for those nodes. The 1 Mbps rate comfortably covers short in-cabinet CAN networks, while the 5 V transceiver supply matches the regulated rails already present in control cabinets. Standby operation lets the controller keep the bus quiet during maintenance mode so other nodes see a predictable bus state, and the small SOIC-8 outline leaves room for the connector and protection circuitry on a crowded elevator car board.
Recommandé
3.3 V Microcontroller Sensor Hub Node
Compact sensor hubs built around modern 3.3 V MCUs often lack a 5 V logic-compatible CAN interface, and the TLE7250GVIOXUMA2 solves this through its dedicated VIO pin set to 3.3 V. The bus side still runs from a 4.75 V to 5.25 V supply, so the transceiver can be powered from a local 5 V rail while the digital side matches the MCU. The 100 mV receiver hysteresis preserves data integrity on long sensor cables, and the half-duplex 1/1 arrangement is exactly what a single host CAN port requires. This makes it a natural fit for environmental, vibration and energy-monitoring nodes.
Recommandé
CAN-to-Serial Gateway and Test Equipment
Protocol analysers, service tools and gateways that bridge a legacy CAN bus to a serial console are built on a single-transceiver CAN port, and the TLE7250GVIOXUMA2 fits that slot. The device protects the host controller against bus faults and external interference, so a bench instrument connected to a live vehicle or machine bus is less likely to be damaged by transients. The standby input is useful in a test fixture that must keep the bus in a defined recessive state between measurement runs, and the small SOIC-8 footprint leaves room for USB or Ethernet interface electronics beside it.

Guide de sélection
Pick the TLE7250GVIOXUMA1 when the electrical function is identical but you need a different packing/ordering form for your assembly line; both share the same PG-DSO-8-16 footprint, 1 Mbps rate, 1/1 half-duplex configuration and 100 mV receiver hysteresis, so the change is a supply-form decision rather than an engineering one. The family name TLE7250GVIO is equivalent whenever the purchasing channel quotes the family rather than a specific ordering code.
Do not select this part if your network requires CAN FD data rates above 1 Mbps, or if you need galvanic isolation, dual CAN channels, or a bus operating outside the classic CAN physical layer. Those requirements call for a different transceiver family with a different package and pinout, and they cannot be dropped into the same footprint without redesign.

Principaux différenciateurs
- Integrated 3.3 V / 5 V logic level adaptation on VIO (vs Fixed 5 V-logic CAN transceivers)
- Standby operating mode for defined low-power bus states (vs Transceivers without a standby input)
- 100 mV receiver hysteresis with low-emission driver stage (vs Transceivers with lower hysteresis)
- AEC-Q100 automotive qualification in an 8-pin SOIC-8 footprint (vs Non-automotive CAN transceivers in larger packages)
Notes de conception
Route CANH and CANL as a tightly coupled differential pair with a constant spacing, keep the pair length matched within a few millimetres, and avoid stubs, vias and test pads on the bus legs. Place the transceiver close to the bus connector so that the unshielded run on the PCB is minimal. A common mistake is to bring CANH and CANL to the connector on separate layers, which destroys the magnetic coupling and increases radiated emissions.
Decouple the VCC and VIO pins independently with 100 nF ceramic capacitors placed directly at the pins, plus bulk capacitance close to the transceiver. Keep the ground return short and use a solid ground plane under and around the device so that bus return currents do not flow through the logic ground of the host controller. Because VIO may be tied to 3.3 V or 5 V independently of the 5 V transceiver rail, verify that the rail connected to VIO is always within the logic input thresholds before power-up sequencing.
Do not substitute a transceiver with a CAN FD data rate for this design: the TLE7250GVIOXUMA2 is specified for 1 Mbps classic CAN, and a bus running above that rate is not supported. Also confirm the standby pin state at reset. If the host MCU drives the control input at an undefined level during startup, the bus may be left active. Add a pull resistor so the transceiver is always in a defined state before the controller begins transmission.
A CAN transceiver's emissions are dominated by the common-mode voltage on the bus, which is set by the network impedance and termination. Ensure the bus is properly terminated with 120 ohm at both ends of the segment and that the stub lengths stay short, since improper termination produces reflections that increase both emissions and susceptibility. Use a common-mode choke if the harness is long or runs next to switching power stages.
