TLE92623BQXXUMA1

Specialized Overview

The TLE9262-3BQX is a mid-range System Basis Chip (SBC) from Infineon's OPTIREG family, designed for automotive body applications. It integrates two low-dropout voltage regulators: a main regulator delivering up to 250 mA at 5 V and an auxiliary regulator providing up to 100 mA. The device features a high-speed CAN transceiver supporting FD communication up to 5 Mbit/s with Partial Networking capabilities, alongside a LIN transceiver compliant with LIN 2.2 standards. Power management includes four high-side outputs, two HV GPIOs, and three wake inputs. Configuration and diagnostics are handled via a 16-bit SPI interface.

Specialized Feature Summary

• Integrated high-speed CAN transceiver supporting Flexible Data Rate (FD) communication up to 5 Mbit/s with Partial Networking and FD tolerant mode.
• Dual integrated low-dropout voltage regulators offering configurable output currents of up to 250 mA and 100 mA respectively.
• Built-in LIN transceiver supporting LIN 2.2, ISO 17987-4, and SAE J2602 protocols.
• Comprehensive supervision functions including watchdog timers, reset outputs, and thermal protection mechanisms.

Specialized Applications

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

Specialized Procurement Notes

Verify the specific ordering suffix against the manufacturer's current product status documentation. Confirm that the component meets AEC-Q100 qualification requirements for your target automotive application. Ensure compatibility with your system's voltage input range and thermal management constraints before finalizing procurement.

Specialized Selection Notes

Select this component when a single-chip solution combining power regulation, CAN FD, and LIN communication is required for body electronics. Consider the available output currents and the need for Partial Networking support. Evaluate the package type PG-VQFN-48 against your PCB layout space and thermal dissipation needs.
