TLE62512GXUMA3 - 1 MBd HS-CAN Transceiver, ISO 11898-5 | Infineon
MPN: TLE62512GXUMA3 ✓ सक्रियTLE62512GXUMA3 अवलोकन
A CAN transceiver, also called a CAN physical-layer interface or CAN PHY, is the bridge between a microcontroller's CAN controller and a differential CAN bus. It converts logic-level TXD and RXD signals into the differential CANH and CANL bus pair and converts received bus levels back to digital logic. The Infineon TLE6251-2G family belongs to the high-speed CAN (HS-CAN) class of interface ICs, sitting at the physical layer of an automotive communication network.
Key features of the TLE62512GXUMA3 include very low power consumption in Sleep mode, bus wake-up capability, a local wake-up inhibit output to control external circuitry, and split termination to stabilize the recessive bus level. A separate failure diagnosis output gives the host microcontroller a hardware health check on the physical layer, and the device is optimized for low electromagnetic interference, which reduces the need for external shielding and filtering in the ECU.
Technically, the TLE6251-2G is positioned as the successor of the TLE6251G, with excellent passive behaviour in power down. This makes the part well suited to mixed power-supply HS-CAN networks where some nodes are unpowered at times while the bus remains active. The TLE6251G and the TLE6251-2G are pin compatible and function compatible, so the two devices can be used interchangeably on the same PCB land pattern. The separate VIO pin allows the transceiver to be interfaced to microcontrollers supplied from 3.3 V or 5 V without level-shifting logic.
Typical applications include electronic control units in body and powertrain domains, CAN gateways, climate control and comfort modules, sensor nodes in distributed vehicle networks, industrial CANopen and DeviceNet equipment, and diagnostic interfaces in workshop tooling.
When laying out the board, place the 100 nF and 1 uF supply decoupling capacitors directly at the VCC and VIO pins, and keep the CANH and CANL traces short, impedance-matched, and free of stubs. Use the split termination feature instead of fitting a single 60 ohm resistor so that split values can be tuned for EMC margin.

सामान्य अनुप्रयोग
TLE62512GXUMA3 के लिए उपयुक्त है 6 अनुप्रयोगs: Automotive Body Control Unit CAN Interface, Powertrain and Chassis Network Node, CAN Gateway and Communication Hub, Industrial CANopen and DeviceNet Equipment, Vehicle Sensor and Actuator Node, Automotive Diagnostic and Workshop Interface.
Automotive Body Control Unit CAN Interface
The TLE62512GXUMA3 gives a body control unit a 1 MBd ISO 11898-5 physical layer for door, lighting, and climate subsystems sharing one HS-CAN backbone. Its passive behaviour in power down matters in mixed power-supply vehicles, where a gateway node may be asleep while others transmit, so an unpowered transceiver must not disturb the recessive bus level. The split termination option and the separate failure diagnosis output both help the ECU qualify EMC margin and confirm bus health at self-test time, while the 14-pin PG-DSO-14 package keeps the footprint compact for densely populated body modules.
अनुशंसित
Powertrain and Chassis Network Node
In a powertrain or chassis node, the TLE62512GXUMA3 links a controller to a noisy vehicle bus where radiated and conducted emissions are tightly constrained. The device is optimized for low electromagnetic interference, so the ECU can pass CISPR 25 style emissions testing with less external filtering, and the 1 MBd HS-CAN rate matches the throughput expected of powertrain messaging. AEC-Q100 qualification supports use in this domain, and the separate VIO input lets the transceiver interface with a lower-voltage domain logic without adding level shifters.
अनुशंसित
CAN Gateway and Communication Hub
A gateway that bridges CAN segments benefits from the TLE62512GXUMA3 because bus wake-up lets a sleeping gateway module be revived by traffic on any connected segment, while the local wake-up inhibit output controls the external circuitry that holds the gateway in reset or removes it from the bus. Passive behaviour in power down ensures that a gateway segment can be powered off during shutdown without corrupting the recessive level of the remaining active network. The 1 MBd ISO 11898-5 compliance makes it interoperable with legacy HS-CAN devices in mixed-generation vehicle fleets.
अनुशंसित
Industrial CANopen and DeviceNet Equipment
For industrial CANopen masters, remote I/O modules, and DeviceNet sensors, the TLE62512GXUMA3 provides a 1 MBd physical layer that meets ISO 11898-5 timing so it interoperates with a wide installed base of controllers. The separate VIO input is useful in factory equipment where the logic rail is 3.3 V while the transceiver core stays at 5 V, removing a discrete level-shifter stage from the board. Bus wake-up supports remote station reconnection, and the failure diagnosis output gives the PLC a hardware indication of bus health for maintenance logging.
अनुशंसित
Vehicle Sensor and Actuator Node
Distributed sensor nodes and actuator drivers in a vehicle often sit at the end of a CAN branch where space, cost, and standby current dominate. The TLE62512GXUMA3 combines a 14-pin PG-DSO-14 footprint with very low power consumption in Sleep mode, so a node that only wakes on bus traffic does not drain the vehicle battery. Local wake-up inhibit gives the node a way to mask its own wake path, avoiding a wake storm when several parked modules share a bus, and the small package leaves PCB area for the sensing and drive circuitry.
अनुशंसित
Automotive Diagnostic and Workshop Interface
Diagnostic tools that tap into an existing vehicle CAN network rely on a transceiver that behaves predictably and does not disturb the bus during connection or removal. The TLE62512GXUMA3 offers bus wake-up for triggering a diagnostic session on a sleeping vehicle network and a failure diagnosis output that indicates physical-layer faults to the tool firmware. Its low EMI behaviour reduces reflections on the stub connection used by workshop equipment, and the ISO 11898-5 compliance guarantees correct arbitration with the many legacy ECUs found across mixed vehicle generations.

डिज़ाइन नोट्स
Place the VCC and VIO decoupling capacitors immediately at the device pins rather than at the connector or regulator. Use a 100 nF ceramic capacitor in parallel with a 1 uF capacitor on each supply pin, with a short ground return and a solid ground plane directly under the transceiver. Keep the CANH and CANL traces as a tightly coupled differential pair with continuous reference plane underneath, avoid any stubs, and route the pair away from switching nodes and antenna feeds.
Use the split termination feature rather than a single 60 ohm resistor across CANH and CANL. The split network lets the recessive common-mode voltage be tuned, which reduces radiated emissions and improves immunity in the vehicle environment. Mount the termination network at the physical end of the bus only, not at every node, and keep the connection from the transceiver to the bus connector as short as possible to limit stub reflections that cause data errors at 1 MBd.
The VIO input may be tied to the microcontroller supply rail so that TXD and RXD logic levels match the MCU, while VCC stays at 5 V for the transceiver core. Do not leave VIO floating. In sleep designs, drive the sleep or standby control pin from the MCU so the node can be woken either by bus traffic or locally, and use the local wake-up inhibit output to prevent repeated wake attempts from masked nodes.
Do not substitute an 8-pin HS-CAN transceiver such as the TJA1057 family for the TLE62512GXUMA3. The competitor devices use a smaller SOIC-8 footprint with a different pin arrangement and a different VIO arrangement, so they are not drop-in and require a PCB respin. When upgrading within Infineon, verify the wake-up inhibit and failure diagnosis pin functions in the datasheet pin table before release, because the earlier TLE6251G generation behaves differently in power down.
