TLE6263GNUMA1 - LS-CAN Transceiver with LDO & HS Switch | Infineon
MPN: TLE6263GNUMA1 ✓ AktifTLE6263GNUMA1 Genel Bakış
A CAN transceiver is the physical-layer interface between a microcontroller and the differential CAN bus. The "half" designation means the device implements one transceiver channel rather than two, which lowers board area and supply current when a node needs only one bus connection. The LS-CAN family from Infineon is optimised for body, comfort and low-speed vehicle networks running at classical CAN data rates, where robustness against bus faults, sleep current and wake-up behaviour matter more than maximum bandwidth.
The key feature of the TLE6263 is integration: besides the CAN transmitter and receiver, the same silicon carries an internal LDO that supplies the transceiver's own logic rail, plus a high-side switch that can drive an external load or act as a wake-up path. This removes separate regulator and load-switch components from the module, shrinking the PCB area and reducing the component count for ECUs, door modules and sensor nodes.
Because the transceiver, regulator and switch are combined, the device reduces the number of external passives a designer must qualify. The integrated LDO avoids the need for a discrete supply for the transceiver logic domain, while the high-side switch provides a controlled output for downstream circuitry, typically with enable control from the host microcontroller.
Typical applications include automotive body control units, door and window modules, comfort systems, seat and climate sensor nodes, as well as industrial and building automation CAN nodes that use the same low-speed CAN physical layer.
Design considerations focus on bus termination (120 ohm split termination), correct CANH/CANL routing away from switching nodes, stable decoupling close to the LDO and transceiver supply pins, and validating sleep current and wake-up timing against the system power budget. Use the Infineon TLE6263 datasheet for the authoritative pin assignment, electrical limits and timing values.

Tipik Uygulamalar
TLE6263GNUMA1 için uygundur 6 uygulamas: Automotive Body Control Unit (BCU) CAN Interface, Door and Window Module CAN Node, Comfort and Sensor Node with Local Load Switch, Industrial CAN Gateway with Regulated Local Rail, Vehicle Lighting and Exterior Node, CAN-to-Analog Sensor Interface.
Automotive Body Control Unit (BCU) CAN Interface
The TLE6263GNUMA1 suits body control units that terminate a single low-speed CAN segment. Because the device integrates the LS-CAN transceiver with an LDO and a high-side switch in one PG-DSO-28-27 package, a module can source its own regulated logic rail and switch an external load without adding separate regulator and load-switch ICs. In a distributed body node this reduces BOM count and routing, and the single-channel half architecture lowers quiescent current compared with a dual-channel transceiver. Because the CAN data rate, VCC range and sleep current were not carried in the verified distributor data, engineers should confirm these limits in the Infineon TLE6263 datasheet before release, and verify the 120 ohm split termination network and CANH/CANL routing on the final layout.

Door and Window Module CAN Node
Door, window and seat modules on low-speed vehicle networks typically need one CAN channel, a local regulated supply and a switched output for a motor or latch driver. The TLE6263GNUMA1 provides exactly that combination in a single 28-lead DSO outline: the transceiver handles the differential bus interface, the internal LDO supplies the transceiver logic domain, and the high-side switch drives or enables the external actuator. Consolidating three functions cuts the footprint that is critical in a space-constrained door module and reduces the number of decoupling networks to qualify. The wake-up path through the high-side switch also supports low-quiescent-current sleep designs. Verify bus fault behaviour, standby current and the wake-up timing against the Infineon TLE6263 datasheet, since these figures were not present in the verified web data.

Comfort and Sensor Node with Local Load Switch
Small comfort and sensor nodes, such as seat occupancy, ambient temperature or HVAC sensors, are often deployed in large numbers where per-node standby current dominates the system power budget. The TLE6263GNUMA1 integrates an LDO with the LS-CAN transceiver, removing one supply rail and its associated inductor or regulator package, while the integrated high-side switch provides a controlled output for the sensor or indicator. Sharing the transceiver's own supply domain also simplifies the power tree and reduces the number of rails to sequence. In a 32-node network the per-node savings compound meaningfully. The exact sleep and standby currents, supply voltage range and operating temperature grade must be read from the Infineon TLE6263 datasheet before the node power budget is signed off.
Önerilen
Industrial CAN Gateway with Regulated Local Rail
Industrial CAN gateways and building-automation controllers frequently need a robust low-speed CAN physical layer plus a locally regulated rail for sensors or a modem. The TLE6263GNUMA1 places the LS-CAN transceiver, an LDO and a high-side switch in one PG-DSO-28-27 device, which simplifies the power tree and limits the number of external passives on a crowded gateway board. The high-side switch can enable a downstream sensor bank or a termination-presenting stage, and the integrated LDO keeps the transceiver supply clean without an extra regulator footprint. As a half transceiver it is ideally paired with a second channel when the gateway terminates two bus segments. Confirm the operating temperature grade, CAN compliance and fault behaviour from the Infineon TLE6263 datasheet, as they were not included in the verified distributor data.
Önerilen
Vehicle Lighting and Exterior Node
Exterior lighting modules such as tail lamps, position lamps and side markers sit on low-speed CAN segments and need a switched output for the LED or bulb driver stage. The TLE6263GNUMA1 combines the CAN transceiver with a high-side switch that can source the driver enable, plus an LDO that supports the transceiver and local logic domain from a single incoming supply. This consolidation removes a discrete load switch and regulator from the lamp module, lowering cost and improving vibration tolerance by reducing solder-joint count in a harsh environment. Care must be taken with the high-side switch current capability and thermal behaviour, which should be verified against the Infineon TLE6263 datasheet and the maximum load current of the lighting driver. The CAN data rate limit and short-circuit protection features also require datasheet confirmation.
Önerilen
CAN-to-Analog Sensor Interface
In mixed analog/digital systems, a CAN node often feeds a sensor front end that needs a stable local supply. The TLE6263GNUMA1 provides that supply through its integrated LDO, and because the LDO sits inside the same package as the transceiver, the analog domain can be referenced to the transceiver ground with a short, low-impedance path, helping to keep noise out of the measurement chain. The high-side switch provides a defined enable for the sensor supply, allowing the front end to be powered down in standby to save current in battery-fed installations. Keep the analog routing physically separated from CANH/CANL to avoid injecting bus edges into the measurement path. Verify the LDO output options, ripple and enable polarity in the Infineon TLE6263 datasheet, as they were not part of the verified web data.

Tasarım Notları
Place the transceiver supply decoupling capacitor directly between the VCC pin and the ground reference of the PG-DSO-28-27 footprint, as close to the device as the land pattern allows. Because the LDO is integrated in the same package as the transceiver, its supply pin shares a common return path with the CAN receiver. Keep this loop area minimal to avoid picking up bus edges. Route CANH and CANL as a tight, symmetric, 50 ohm-impedance-matched differential pair away from switching nodes, high-current inductors and the high-side switch output, and provide a 120 ohm split termination (60 ohm per leg to ground) at each bus end.
The integrated LDO and high-side switch change the power-tree design: the transceiver logic domain no longer needs a dedicated regulator, and the high-side switch output is driven from the same supply, so the input rail must be sized to cover the transceiver, the LDO load and the switched load simultaneously. Use the Infineon TLE6263 datasheet for the maximum total input current and the high-side switch continuous and short-circuit current limits before choosing the upstream supply and any protection fuse. Decouple the switched output separately at the load to limit transient coupling back into the transceiver supply.
Power dissipation in this part comes from the transceiver itself plus the LDO drop and the high-side switch in its on state. Estimated: with VIN minus VOUT across the LDO and a 50 mA load, dissipation is roughly VIN minus VOUT times 0.05 A; for example a 5 V in, 3.3 V out condition at 50 mA gives about 85 mW, plus the high-side switch conduction loss of I_switch squared times R_on, which for 100 mA at 1 ohm is only 10 mW. Confirm R_on and thermal resistance from the Infineon datasheet and provide copper area on the exposed pad.
Do not treat this device as a high-speed CAN FD transceiver: the TLE6263 family is an LS-CAN (low-speed CAN) product, and substituting it into a CAN FD node will fail at the physical layer even if the pin count matches. Also note that TLE6263GNUMA1 is a specific ordering variant with bulk packing; if your BOM specifies tape-and-reel or a different packaging code, confirm the full ordering information in the Infineon TLE6263 datasheet and the distributor stock records, because Octopart currently lists only one distributor for this code.
Uyumluluk Bilgisi
The verified web data contains only distributor listings (DigiKey via Rochester Electronics, Octopart, GoodChip, IC-Components, Veswin, Xilinx-Components) and the manufacturer description "INTEGRATED LS-CAN, LDO AND HS-SW" for ordering code TLE6263GNUMA1. No RoHS, REACH, AEC-Q100, lead-free or halogen-free statements appeared in the retrieved data, so all compliance fields are marked unknown and must be confirmed from the Infineon TLE6263 datasheet or the Infineon material declaration.
