The RTQ2081C-QF is a highly integrated PMIC designed for automotive radar applications. It includes three buck converters, one high PSRR low-dropout (LDO) regulator, and one general low-dropout (LDO) regulator. The high-voltage buck 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 RTQ2081C-QF features built-in overvoltage and undervoltage monitoring circuits on each channel, an error output indicator, and fault status reporting via I2C for enhanced functional safety.The RTQ2081C-QF is equipped with a standard built-in WDT (Watchdog Timer) function. This feature offers versatility for a wide range of applications through configurable settings 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 RTQ2081C-QF is available in a WET-WQFN4x4-24A 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.
