TLE9263BQXV33XUMA1

Specialized Overview

The TLE9263BQXV33 is a monolithic System Basis Chip (SBC) in a PG-VQFN-48 package, designed for automotive CAN-LIN applications. It features a 3.3 V main LDO (250 mA), a 5 V auxiliary LDO (100 mA), and an external regulator driver (up to 350 mA). Communication includes one HS-CAN transceiver supporting FD up to 5 Mbps and two LIN 2.2 transceivers. The device provides four high-side switches, three wake inputs, and two GPIOs. It operates within a supply voltage range of 4.75 V to 28 V and supports temperatures from -40 °C to +150 °C.

Specialized Feature Summary

• Integrated power management with multiple low-dropout regulators and high-side switches for load distribution.
• Dual communication interfaces including a high-speed CAN transceiver with FD support and dual LIN transceivers.
• Advanced low-power modes with configurable cyclic wake and sense capabilities for battery optimization.
• Comprehensive supervision functions including watchdog timers, reset generation, and thermal protection.

Specialized Applications

• Body Control Modules (BMC)
• Passive keyless entry and start modules
• Gateway applications
• Heating, ventilation and air conditioning (HVAC)
• Seat, roof, tailgate, trailer, door and other closure modules

Specialized Procurement Notes

Verify the specific suffix XUMA1 corresponds to the required reel packaging configuration before ordering. Confirm that the 3.3 V output variant matches the system requirements, as 5 V variants exist within the same family. Ensure compatibility with existing firmware, as the datasheet notes software compatibility across the TLE926x family.

Specialized Selection Notes

Select this variant specifically when a 3.3 V main regulator is required for the microcontroller supply. Consider the TLE9263 over the TLE9262 if dual LIN transceivers are necessary for the application architecture. Evaluate the need for the external PNP transistor configuration if higher current loads or load sharing are required beyond the internal regulator limits.

Specialized Part Context

This component belongs to the OPTIREG Mid-Range+ SBC family. It shares hardware and software compatibility with other members like the TLE9262 and TLE9261. The primary distinction lies in the number of integrated LIN transceivers; the TLE9263 includes two, whereas the TLE9262 includes one. This makes it suitable for more complex network topologies requiring additional LIN nodes.

Specialized Replacement Considerations

TLE9263BQXXUMA1 is listed as a previous part number revision. Verify functional equivalence if substituting. No other direct cross-model replacements are confirmed in the provided documentation without potential architectural changes regarding LIN channel counts.
