The PQ6258XQ device family is an automotive functional safety multi-output power management integrated circuit, which integrates multiple DC-DC regulators and multiple low-dropout (LDO) regulators for microcontroller, sensors, peripheral ICs and communication interfaces. DC-DC regulators consists of an asynchronous pre-boost controller to support low battery voltage during cold crank, a pre-buck converter for all post regulators, and an internal or external post-buck regulator for MCU core supply. LDOs include a low quiescent current (IQ) standby LDO for standby supply, a μC LDO for microcontroller main supply, a COM LDO for communication supply, a REF LDO for ADC supply, and up to 3 tracker LDOs for sensor supply.
