TLE7263E 概述
A system basis chip is an automotive power and communication component that consolidates supply regulation, high-side switching, diagnostic interfaces, and network transceivers. In the hierarchy, this TLE7263E combines a LIN transceiver, high-speed CAN interface, two low-dropout voltage regulators, and a high-side switch to support centralized electrical architecture and body or comfort-system electronics.
The principal verified features include compatibility with the LIN 2.0 specification and ISO 9141, a 13.5 V supply configuration, a 1 mA supply-current figure reported by a distributor index, and two integrated low-dropout regulators. The 16-bit SPI interface allows a host microcontroller to configure and monitor the system basis functions, while stop and sleep modes support reduced-power operating states.
The TLE7263E consolidates several discrete automotive functions into one IC, reducing PCB area and the number of external network-interface components. Its 150 mA, 5 V regulator capability is suitable for low-power automotive loads, although it is not intended to power loads whose current exceeds that rating. The exposed-pad package also requires attention to PCB thermal design and copper placement.
Typical uses include automotive body-control modules, door and seat controllers, climate-control electronics, lighting-control units, LIN-connected actuators, gateways combining LIN and CAN, and other low-voltage vehicle electronics. Designers should verify transceiver limits, regulator startup behavior, pin electrical limits, and watchdog operation directly against the manufacturer datasheet before production release.
For layout, place the device close to protected vehicle-power entry, route high-current switched paths with adequate copper, and keep sensitive CAN and LIN nodes compact and isolated from switching edges. Confirm startup sequencing, diagnostic behavior, watchdog timing, and sleep-mode current in the target ECU environment.
This page combines verified manufacturer-linked specifications, distributor package information, application guidance, and replacement-policy checks. It does not claim an unqualified drop-in alternative because the supplied cross-reference results did not verify five pin-compatible parts.

典型应用
TLE7263E 适用于 6 应用s: Automotive LIN Actuator Controller, CAN-LIN Body Control Gateway, Door and Seat Control Module, Climate-Control Electronics, Automotive Lighting Control Unit, Automotive Sensor Hub.
Automotive LIN Actuator Controller
The TLE7263E fits a LIN actuator controller because it combines a LIN 2.0-compatible transceiver, a 30 kOhm internal pull-up, and a 5 V regulator rated at 150 mA in one PG-DSO-36-24 device. The integrated regulator can supply a small solenoid, sensor, valve driver, or indicator circuit when its transient and thermal demand remain within limits. The 16-bit SPI interface also lets the host MCU configure and monitor system functions instead of relying on separate CAN and power-control ICs. Designers should verify actuator peak current, flyback behavior, bus fault handling, and exposed-pad thermal performance against the full datasheet.
推荐
CAN-LIN Body Control Gateway
The TLE7263E is appropriate for a compact automotive gateway or body-control node that needs both HS-CAN and LIN connectivity. Its verified integration combines ISO 9141-compatible CAN, LIN 2.0-compatible communication, two LDOs, a 150 mA 5 V rail, a high-side switch, SPI control, and a window watchdog. This can reduce board area for supervisory modules that translate or aggregate vehicle-network information. The 13.5 V supply figure must be reconciled with the ECU's production battery and transient specification, while CAN and LIN routing require protection, grounding, and diagnostic validation.
推荐
Door and Seat Control Module
A door or seat module can use the TLE7263E to consolidate local power regulation and vehicle-network communication. Its 5 V, 150 mA regulator suits low-power switches, position sensors, indicators, and logic when their combined transient load is controlled. Integrated LIN capability supports distributed vehicle sub-buses, while HS-CAN provides backbone or diagnostic connectivity. The 50 µA sleep-mode figure and controller stop-mode support are useful for parked-vehicle current budgets, but actual module current depends on external loads, pull networks, wake conditions, and firmware. Copper spreading for the exposed pad is especially important under repeated switching loads.
推荐
Climate-Control Electronics
The TLE7263E can support distributed climate-control electronics where a module needs a regulated low-voltage rail and vehicle-network communications in limited board area. The 5 V output rated at 150 mA can serve compatible control logic and small sensor or indicator loads, while HS-CAN and LIN interfaces support centralized vehicle networks. Two LDOs allow additional rail organization when their limits and external components meet the datasheet requirements. Fan, compressor, heater, or actuator power should not be placed directly on this rail without a suitable driver. Engineers must validate sleep behavior, wake timing, watchdog settings, EMI margin, and thermal performance across the complete operating temperature range.
推荐
Automotive Lighting Control Unit
For low-current automotive lighting-control electronics, the TLE7263E offers a 5 V rail, integrated communication interfaces, a high-side switch, and supervisory functions in one package. The 150 mA regulator is appropriate only for logic and control loads, not for lamp current. The high-side switch and external protection network must be checked against the exact lighting load, fault behavior, and automotive transient requirements. SPI-connected diagnostics and the window watchdog can improve system control, while sleep mode helps manage parked-vehicle demand. A lighting design should use separate appropriately rated drive circuitry and validate brownout, open-load, short-circuit, and thermal behavior.
推荐
Automotive Sensor Hub
The TLE7263E can act as a low-power hub for distributed automotive sensors that communicate through LIN or CAN and require a compact regulated supply. The LIN transceiver's integrated 30 kOhm pull-up simplifies the bus interface, while the 5 V rail rated at 150 mA can power compatible sensing electronics and conditioning components. HS-CAN support allows the hub to relay information to a higher-level network node. The two LDOs may organize additional low-current rails if their requirements are compatible. Design verification should include sensor-transient loading, ground-offset behavior, watchdog settings, wake current, and the temperature limits associated with the vehicle compartment.

关键差异点
- Integrates two vehicle-network interfaces and regulated power （对比 TJA1021T/20/C)
- Provides system-level power supervision （对比 SN75176BD)
- Supports low-power distributed vehicle nodes （对比 KSZ8001LI)
设计说明
Treat the PG-DSO-36-24 footprint as a controlled automotive land pattern. Place input, output, and reference components at the locations specified by the manufacturer layout guidance, preserve the exposed-pad copper geometry, and avoid adding solder-mask features unless assembly documentation approves them. The verified package information confirms an exposed pad but does not provide a complete land pattern, so use the full Infineon footprint rather than estimating dimensions.
Budget the regulated 5 V load against the verified 150 mA rating, including startup inrush, sensor transients, indicator loads, and external circuitry. The 13.5 V supply entry must also be checked against the complete automotive battery and transient range. Do not drive pumps, fan motors, heater elements, or high-current lamps from this regulator; use an appropriately rated switch and protection stage while retaining the TLE7263E for control logic.
Do not substitute a standalone CAN transceiver for the TLE7263E. A CAN-only device may match one bus function but will not provide the integrated LIN transceiver, two LDOs, high-side switch, window watchdog, SPI configuration, and sleep behavior. Because no verified same-footprint replacement was supplied, qualify any future alternate through pin-by-pin, clock, watchdog, regulator, CAN, LIN, ESD, and fail-safe comparison.
Route CAN and LIN according to their bus topology and impedance requirements, keeping sensitive nodes compact and separated from high-dv/dt switched outputs. Provide the required protection network and return-path continuity, and verify timing and radiated-emissions behavior on the completed module. The TLE7263E's 30 kOhm internal LIN pull-up simplifies the bus, but external loading, fault conditions, and network-level termination still require schematic review.
合规信息
