Powerquark has introduced a new high-end automotive-grade MCU PMIC PQ6258XQ, designed to provide efficient and stable power support for MCU core in systems such as domain controllers, body control modules, powertrains, and ADAS. PQ6258XQ has obtained ISO26262 ASIL-D functional safety certification and AEC-Q100 certification. It features low static current and high energy efficiency, supporting the diverse functions of high-end MCUs in automotive systems.
PQ6258XQ employs a high-voltage converter pre-regulation + low-voltage converter output target voltage architecture, integrating multiple power rails, including 1 buck-boost controller, 2 buck converters, 1 high-voltage LDO, and multiple post-LDOs for MCU main power supply, core power supply, peripheral interface power supply, ADC power supply, and sensor power supply. In standby mode, the static current is as low as 20μA, and in sleep mode, it is as low as 300μA, effectively reducing energy dissipation and extending the driving miles of electric vehicles.
PQ6258XQ offers system-level functions such as AMUX and external voltage monitoring, and supports flexible power-up/power-down sequences. It is compatible with mainstream automotive-grade MCUs.
