TLE7263EXUMA2

Specialized Overview

The TLE7263EXUMA2 is a System Basis Chip (SBC) designed for automotive CAN-LIN gateway applications. It integrates a high-speed CAN transceiver supporting up to 1 MBaud, a LIN transceiver compatible with specifications 1.3 through 2.1 and SAE J2602-2, and dual low-dropout voltage regulators providing 5 V outputs at 150 mA each. The device includes a 150 mA high-side switch, four monitoring/wake-up inputs, and a window watchdog. Communication with the microcontroller is handled via a standard 16-bit SPI interface. It operates within an extended temperature range of -40°C to +150°C and is housed in a PG-DSO-36-53 package.

Specialized Feature Summary

• Integrated HS-CAN and LIN transceivers with bus short-circuit protection and wake-up capabilities
• Dual 5V LDO voltage regulators with independent control and overload protection
• Configurable high-side switch for periodic external circuit supply during low power modes
• Advanced low power management including Sleep, Stop, and Cyclic Sense/Wake modes

Specialized Applications

• CAN-LIN gateway modules
• Automotive body control units
• Smart power distribution systems

Specialized Procurement Notes

Verify component authenticity by checking the marking code on the PG-DSO-36-53 package against official Infineon documentation. Confirm the specific suffix matches the requested reel or cut tape configuration. Ensure the supplier provides valid traceability records for automotive-grade components.

Specialized Selection Notes

Select this component when a combined CAN and LIN interface is required alongside integrated power regulation. The dual 5V LDOs are suitable for powering both the microcontroller and internal CAN modules. Verify that the 150 mA current rating of the high-side switch meets the requirements for any connected peripheral loads.
