RTQ2079-QF Functional Safety PMIC for Automotive Camera Sensors/ Modules 1 General Description The RTQ2079-QF is a highly integrated PMIC designed for automotive camera applications. It includes three step-down converters, one high PSRR low-dropout (LDO) regulator, and one general low-dropout (LDO) regulator. The high-voltage step-down converter operates with an input voltage range of up to 24V and is capable of sustaining a 36V load dump. It is suitable for a direct connection to a 12V battery or Power Over Coaxial (PoC) connection. The RTQ2079-QF offers overvoltage and undervoltage monitors, two error input receivers, one error output indicator, and fault status reported by I2C for system fault reporting purpose.
