The Texas Instruments O3850AQDCARQ1 is a multirail power supply designed for microcontrollers in safety-relevant automotive applications. It is qualified for automotive use and AEC-Q100 certified.
Key electrical specifications include an input voltage range of 7V to 36V for initial battery power-up, and 4V to 36V for full functionality. The device features multiple supply rails with internal FETs, including a 6V synchronous buck-boost preregulator, a 5V LDO for CAN and peripherals, and a 3.3V or 5V LDO for the MCU. It also includes two protected LDOs for sensor supply or peripherals.
Monitoring and protection features are extensive, with independent undervoltage and overvoltage monitoring on all regulator outputs, battery voltage, and internal supplies. The device is protected with current limit and overtemperature prewarning and shutdown. The microcontroller interface includes watchdog functions, diagnostic states, and a reset circuit.
Packaged in a 48-HTSSOP with an exposed pad, the O3850AQDCARQ1 is designed for surface mount applications. Its operating temperature range is -40°C to 125°C (TA).
