<!-- Paste General Description -->The RTQ2079-QA 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-QA offers overvoltage and undervoltage monitors, two error input receivers, one error output indicator, and fault status reported by I<SUP>2</SUP>C for system fault reporting purpose.The device offers system design flexibility with I<SUP>2</SUP>C or factory-trimmed configurable functions, including adjustable output voltage for each channel, customizable power-on sequencing, and overvoltage (OV) or undervoltage (UV) monitor threshold voltage. The RTQ2079-QA is available in a WET-WQFN-24AL 4x4 package with wettable flanks.The recommended junction temperature range is -40°C to 150°C, and the ambient temperature range is -40°C to 125°C.
