TLE7263E

Specialized Overview

The TLE7263E is an integrated System Basis Chip (SBC) designed for CAN-LIN gateway applications in automotive environments. It features a high-speed CAN transceiver supporting up to 1 MBaud and a LIN transceiver compatible with specifications 1.3, 2.0, and 2.1, operating at rates up to 20 kBaud. The device includes two low-dropout voltage regulators (LDOs), VCC1 and VCC2, each providing 5 V ±2% output with a maximum current of 150 mA. A 150 mA high-side switch is integrated for external load control. Communication with the host microcontroller is managed via a standard 16-bit SPI interface. The chip supports multiple power modes, including Active, Standby, Stop, and Sleep, with a typical sleep mode current consumption of 50 µA.

Specialized Feature Summary

• Integrated HS-CAN and LIN transceivers with bus wake-up capabilities and short-circuit protection.
• Dual 5V LDOs with 150 mA output capability and overtemperature/short-circuit protection.
• 16-bit SPI interface for comprehensive control, monitoring, and diagnosis.
• Window watchdog circuit with reset feature and fail-safe output generation.

Specialized Applications

• CAN-LIN gateway systems
• Automotive electronic control units (ECUs)
• Microcontroller supply management in harsh automotive environments

Specialized Procurement Notes

Verify component authenticity by checking the manufacturer marking against the datasheet specifications. Confirm the package type matches PG-DSO-36-24 with an exposed pad. Ensure the ordering suffix corresponds to the required tape and reel quantity. Cross-reference the revision level with the latest official documentation to confirm feature compatibility.

Specialized Selection Notes

Select this component when a combined power management and communication solution is required for CAN-LIN architectures. Verify that the 150 mA regulator current meets the load requirements for both the microcontroller and peripheral devices. Ensure the system design accommodates the specific thermal dissipation needs of the DSO-36-24 package under maximum load conditions.

Specialized Part Context

The TLE7263E belongs to Infineon's OPTIREG family of system basis chips. It is specifically engineered to bridge the gap between high-speed data transmission protocols and robust power distribution in vehicle networks. This integration reduces board space and simplifies the overall system architecture compared to discrete solutions.

Specialized Replacement Considerations

Check for updated revisions within the TLE7263 series. Verify pin-to-pin compatibility if considering alternative SBCs from other manufacturers. Ensure that any substitute part supports the same CAN/LIN specifications and regulatory automotive qualifications.
