TLE8458GXUMA1 - Integrated 5V LIN Transceiver | Infineon
MPN: TLE8458GXUMA1 ✓ AktifTLE8458GXUMA1 Ringkasan
A LIN transceiver is a physical-layer interface IC for the LIN bus, a low-cost single-wire automotive communication network. Its hierarchy runs from LIN transceiver to vehicle-network transceiver, automotive interface IC, and power-management semiconductor. Integrating the regulator eliminates a separate 5 V supply circuit for compatible microcontroller domains and reduces PCB area, component count, and the number of power-supply interconnects.
Verified distributor data identifies the TLE8458GXUMA1 as a fixed positive, single-output LDO regulator with a minimum input voltage of 5.5 V, 2% maximum voltage tolerance, eight gull-wing terminals, and a 10.4 kBd LIN interface rate. The same 5.5 V minimum input condition permits the regulator and LIN transceiver to operate from a common automotive supply while providing a regulated 5 V rail to the attached microcontroller.
The LIN side provides one driver and one receiver for a typical LIN master or slave node. It supports nodes requiring combined communication and regulated supply, such as door modules, body controllers, seat controllers, climate-control panels, lighting modules, and compact automotive sensor nodes. Because LIN uses a single-wire bus, the interface reduces wiring cost compared with a multiwire automotive network while retaining a defined physical-layer interface for distributed vehicle electronics.
The 8-pin DSO package is surface mount and compact, but the exposed environmental requirements of automotive electronics make PCB planning important. Route the LIN connection away from sensitive analog and communication nodes, keep the regulator output close to its decoupling capacitor, and use a return path that avoids high-current switching currents. Verify absolute maximum voltages, output load conditions, bus termination strategy, and supply transient behavior against the manufacturer datasheet before releasing a production design.
Pricing, exact absolute maximum ratings, temperature limits, output-current capability, and a complete pin map were not supplied in the verified data and therefore remain marked as data needed rather than inferred. This page consolidates distributor identification, the TLE8458G family relationship, pin-compatible stand-alone LIN-transceiver context, and practical application guidance beyond a distributor catalog listing.

Aplikasi Biasa
TLE8458GXUMA1 patut untuk 6 aplikasis: Automotive Door Control Module, Body Control Module LIN Node, Seat and Climate Control Panel, Automotive Lighting Controller, LIN Automotive Sensor Node, Automotive Access and Convenience Module.
Automotive Door Control Module
The TLE8458GXUMA1 suits a door-control node that must communicate over a LIN bus and power a local controller from one device. Its verified 10.4 kBd LIN rate and one-driver, one-receiver arrangement provide the physical interface for a single LIN node, while the integrated 5 V regulator removes a separate LDO from the 5.5 V minimum-input supply domain. The eight-terminal surface-mount DSO package also helps preserve PCB area in space-constrained body modules. Before release, confirm the regulator output-current rating against the controller and attached loads, and verify the LIN pull-up, wake-up, and fault-handling requirements against the Infineon datasheet.
Body Control Module LIN Node
The TLE8458GXUMA1 can support a distributed body controller that combines LIN communication with a locally regulated 5 V domain. Instead of allocating a separate regulator and its surrounding capacitor and routing to an isolated transceiver, one IC can provide the 10.4 kBd LIN physical layer and the 5 V supply function. This is particularly useful in modules with limited board area and moderate controller current. The 5.5 V minimum input rating must be checked against the raw automotive supply after transients and load dump, while the complete pinout and decoupling requirements must be taken from the manufacturer documentation rather than a generic eight-pin footprint.
Seat and Climate Control Panel
A seat-adjustment or climate-control panel can use the TLE8458GXUMA1 where the controller needs both a 5 V rail and LIN connectivity. Combining the interface and regulator reduces component count and avoids routing a separate regulator output across the PCB, which can improve robustness against supply noise and board-area constraints. The integrated interface supports a one-driver, one-receiver LIN node at the verified 10.4 kBd rate. Validate the available regulator current against the panel's controller, sensors, LEDs, and actuator drivers, and confirm that the exact order code provides the 5 V output and environmental grade required by the vehicle platform.
Automotive Lighting Controller
The TLE8458GXUMA1 is applicable to a small LIN lighting module that combines bus communication with regulated controller power. The verified integration allows a compact node to use one IC instead of separate LIN and regulator components, while the 8-pin DSO-8-16 package supports automated surface-mount assembly. The 5.5 V minimum regulator input and fixed 5 V output provide the baseline architecture for a compact driver, but they do not by themselves describe LED-string current capability. Use the device only for logic and control supply, then drive the LED load with an appropriately rated discrete or integrated power stage. Validate load-dump exposure, transient suppression, and thermal performance at the vehicle level.
LIN Automotive Sensor Node
The TLE8458GXUMA1 fits a remote LIN sensor node that needs a regulated 5 V micro rail and low-speed vehicle-network communication in one package. Its verified 10.4 kBd LIN interface is suitable for the low-bandwidth environment typical of body and comfort sensors, while the integrated regulator can power a controller and low-current sensing circuitry. Consolidation reduces board area and assembly cost, although regulator dynamic performance, quiescent current, and current limit must be confirmed from the datasheet. For analog sensor accuracy, decouple the 5 V rail locally and isolate sensitive sensor returns from the LIN and switching currents.
Automotive Access and Convenience Module
The TLE8458GXUMA1 can support an access-control, mirror, switch, or convenience module that communicates with a vehicle master over LIN. Integrating the 5 V regulator with the one-driver, one-receiver LIN interface reduces the number of components in space-constrained modules and allows local controller power to come from the same supply domain used by the transceiver. The verified 5.5 V minimum input, 2% maximum voltage tolerance, and 10.4 kBd rate describe the essential interface and regulation values. Production use still requires confirmation of automotive qualification, operating-temperature grade, wake-up behavior, bus-receiver thresholds, and protection against reverse battery and load-dump conditions.

Catatan Desain
The TLE8458GXUMA1 is specified with a 5.5 V minimum input voltage and a 5 V regulator output, leaving limited voltage headroom. Verify the automotive supply waveform, reverse-battery behavior, and load-dump protection before connecting the input directly to battery-derived power. If transient energy exceeds the device rating, add the protection network recommended by the vehicle platform or Infineon application guidance. The regulator is intended to power local electronics; a separate power stage may be required for lamps, motors, or other high-current loads.
Place the regulator input and output capacitors directly beside their associated package pins, using the shortest and lowest-inductance connections permitted by the datasheet layout. Keep the LIN bus trace away from the 5 V output and sensitive sensor nodes, and avoid routing it parallel with high-current edge currents. Because the supplied data identifies a DSO-8-16 package, confirm whether the center thermal or exposed pad requires soldering from the manufacturer's land pattern rather than assuming a standard SOIC-8 footprint.
Do not treat the TLE7259-2GE as a functional drop-in replacement simply because the TLE8458Gx family is described as pin compatible with stand-alone LIN transceivers. The TLE7259-2GE is a stand-alone interface, while the TLE8458GXUMA1 also integrates the regulator. A reused board would lose the 5 V regulator function unless that function is added elsewhere. Likewise, verify the suffix-specific output voltage and automotive grade of TLE8458GV33, TLE8458GU, and TLE8458GUV33 before approving them as substitutions.
Review the LIN bus topology, termination, pull-up arrangement, and grounding against the manufacturer datasheet and vehicle-network specification. The integrated regulator output should use a local return path that does not carry LIN return current or actuator current. This helps prevent bus-threshold errors when the node drives a load or shares a ground conductor with a high-current actuator. Test both bus-recessive and bus-dominant states using the exact production harness, including tolerance of the external network nodes.
Maklumat Kesediaan
The verified sources identify automotive LIN use but do not explicitly state RoHS, REACH, AEC-Q100, halogen-free, or conflict-minerals status. These values remain unknown rather than assumed. The datasheet URL points to a distributor-hosted datasheet entry because an official Infineon PDF URL was not included in the supplied search results.
