The A4408 is an automotive-grade power management IC designed to convert battery voltages into regulated outputs for microprocessor and CAN bus power supplies in high-temperature underhood environments. It features a buck or buck-boost pre-regulator with a 2.8 V to 36 V input range, a 5 V/325 mA LDO, a 3.3 V/165 mA LDO, an adjustable 1.25 V/700 mA synchronous buck regulator, and a tracking 5 V LDO with short-to-battery protection. The device includes a programmable watchdog timer, dual bandgaps for reliability, NPOR and POK5V diagnostic outputs, and two fault flags (FF0/FF1). It is supplied in a 38-pin eTSSOP package with an exposed thermal pad and operates from −40°C to 150°C junction temperature. The part is AEC-Q100 qualified and supports PWM frequency adjustment from 250 kHz to 2.4 MHz with external synchronization capability.
