With 15\u03bcA sleep mode current, configurable watchdog, cyclic wake\/sense, and three HV wake inputs, it is designed for automotive body control, door, HVAC, and light control modules. Software compatible across the entire TLE926x and TLE927x SBC family.","working_principle":"The TLE9261-3BQX integrates power management, bus communication, 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 short-circuit protection. The external PNP driver (VCC3) can operate in standalone mode (5V or 3.3V, current limited by external shunt resistor up to 350mA) or load-sharing mode with VCC1. The CAN FD transceiver supports up to 5Mbps with Partial Networking (selective wake via WUF pattern detection). The state machine manages SBC modes: Normal (all functions active), Stop (VCC1\/VCC2 on, CAN monitoring, 44\u03bcA), Sleep (VCC1 off, CAN\/LIN wake capable, 15\u03bcA), Restart (temporary wake from Sleep), and Fail-Safe (safe state). The 4 high-side outputs can drive LEDs, relays, or sensors. The configurable window\/timeout watchdog ensures MCU health, and the SPI provides full diagnostic readback including over-temperature, short-circuit, and open-load flags.","pin_description":"
