With 15\u03bcA sleep mode current, configurable watchdog, cyclic wake\/sense, and both CAN and LIN wake capability, it is the most feature-rich member of the TLE926x family for automotive seat, door, HVAC, and PDU applications. Software compatible across the entire TLE926x and TLE927x SBC family.","working_principle":"The TLE9263-3BQX integrates power management, dual-bus communication (CAN + 2x LIN), and diagnostic functions into a single SBC. The main LDO (VCC1) provides 5V\/250mA for MCU supply. The sensor LDO (VCC2) provides 5V\/100mA with off-board protection. The external PNP driver (VCC3) supports standalone or load-sharing mode. The CAN FD transceiver supports up to 5Mbps with Partial Networking for selective wake. The two LIN transceivers support LIN 2.2a\/J2602 with configurable TXD timeout for bus stuck-dominant protection and LIN Flash mode for fast reprogramming. The state machine manages SBC modes (Normal, Stop, Sleep, Restart, Fail-Safe). All three communication channels (CAN, LIN1, LIN2) can serve as wake sources from Stop and Sleep modes. The 4 high-side outputs and 2 GPIOs provide flexible peripheral control. The 16-bit SPI provides complete configuration and diagnostic access.","pin_description":"
