The RTQ2080-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. The RTQ2080-QF offers overvoltage and undervoltage monitors, two error input receivers, one error output indicator, and fault status reported by I2C for functional safety purposes.The RTQ2080-QF is equipped with a standard built-in watchdog timer function. This feature offers versatility for a wide range of applications through configurable setting for both upper and lower window tolerances.The device offers system design flexibility with I2C or factory-trimmed configurable functions, including adjustable output voltage for each channel, customizable power-on sequencing, overvoltage (OV) or undervoltage (UV) monitor threshold voltage, and the watchdog timeout setting. The RTQ2080-QF is available in a WET-WQFN-24AL 4x4 package with wettable flanks. The recommended junction temperature range is -40°C to 125°C, and the ambient temperature range is -40°C to 125°C.
