TLE62633GXUMA1

Specialized Overview

The TLE6263-3G is a monolithic System Basis Chip designed for automotive body and convenience applications. It integrates a fault-tolerant low-speed CAN transceiver supporting up to 125 kBaud, an LDO voltage regulator providing 5V output with a maximum current of 110 mA, and a high-side switch capable of driving loads up to 150 mA. The device features two wake-up inputs (WK1, WK2), a window watchdog circuit, and a fail-safe output. Communication with the host microcontroller is managed via an 8-bit SPI interface. It operates within a supply voltage range of 4.75 V to 27 V and supports a junction temperature range from -40 °C to 150 °C in a PG-DSO-28-27 package.

Specialized Feature Summary

• Integrated fault-tolerant CAN transceiver with automatic bus failure management for single-wire operation
• Low dropout voltage regulator for internal and external 5V power supply
• High-side switch with cyclic sense capability for external wake-up circuits
• Window watchdog with fail-safe output for critical application supervision

Specialized Applications

• Automotive electronic control units for body and convenience systems
• Central gateway modules requiring integrated power and communication management
• Smart power distribution nodes with CAN connectivity

Specialized Procurement Notes

Verify the specific ordering code against the manufacturer's current product status. Confirm that the PG-DSO-28-27 package variant matches the design requirements. Ensure compliance with AEC-Q100 qualification standards if required for the target automotive application. Check for any recent revisions to the datasheet that may affect pin definitions or electrical characteristics.

Specialized Selection Notes

Select this component when a combined solution for power regulation, high-side switching, and low-speed CAN communication is needed. It is suitable for applications requiring robust bus failure management and low-power standby modes. Consider the thermal resistance of the PG-DSO package and ensure adequate PCB cooling areas are allocated for the ground pins to maintain performance within the specified temperature range.

Specialized Part Context

This component belongs to Infineon's TLE62xx series of System Basis Chips.
