The A81412 is a fully integrated power management IC designed for safety-critical automotive applications, featuring a 2.2 MHz synchronous buck-boost preregulator and six linear regulators with fold-back short-circuit protection. It operates from a 3.2 V to 36 V input range, with a maximum voltage of 40 V, and is AEC-Q100 Grade 0 qualified and ASIL D compliant per ISO 26262. The device includes a 3.3 V microcontroller regulator (VUC), a 5 V regulator (VLDOA), a 5 V A/D reference regulator (VLDOC), two SPI-controlled regulators (VLDOP1 and VLDOP2) with short-to-battery protection, and a configurable VLDOB regulator. It provides watchdog timers, SPI diagnostic reporting, a battery-disconnect switch, and a standby timer. The part is housed in a 48-pin QFN package measuring 7 mm × 7 mm with an exposed thermal pad and wettable flanks.
