TLE9262BQXV33XUMA1

Specialized Overview

The TLE9262BQXV33 is an OPTIREG Mid-Range+ System Basis Chip (SBC) designed for automotive applications. It integrates a main low-dropout regulator providing 3.3 V up to 250 mA and an auxiliary regulator delivering 5 V up to 100 mA with off-board protection. The device features a high-speed CAN transceiver supporting FD communication up to 5 Mbit/s per ISO 11898-2:2016, alongside a LIN transceiver compliant with LIN 2.2/ISO 17987-4/SAE J2602. Power management includes four high-side outputs with typical on-resistance of 7 Ω, two HV GPIOs, and three HV wake inputs. Configuration and diagnostics are managed via a 16-bit SPI interface.

Specialized Feature Summary

• Integrated dual voltage regulators with dedicated off-board usage protection for the auxiliary output.
• High-speed CAN transceiver supporting Flexible Data-rate communication up to 5 Mbit/s.
• LIN transceiver supporting LIN 2.2 standard with flash programming capabilities.
