PMIC - Power Management IC
Infineon‘s power management IC (PMIC) portfolio covers a wide range of embedded applications for IoT, automotive, industrial and consumer products. Our innovative power management technology solutions enhance the performance and reliability of electronic systems.
Energy Harvesting PMICs are tiny, low power solutions. Infineon‘s Energy Harvesting PMIC portfolio offers breakthrough low quiescent and start up current requirements that enable compact energy harvesting systems.
The S6AE10xA family of Energy Harvesting Power Management ICs enable tiny, solar-powered Internet of Things (IoT) devices. They are the world’s lowest-power, single-chip Energy Harvesting PMICs, and can be used with solar cells as small as 1 cm2 due to their low startup and quiescent current. The PMICs are highly integrated, with family members offering power gated outputs, low dropout regulators, CR timers, comparators, and battery backup operation. They are ideal for battery-less Wireless Sensor Nodes (WSNs) that monitor physical and environmental conditions for smart homes, commercial buildings, factories, infrastructure and agriculture.

Infineon‘s automotive power management ICs (PMICs) provide highly-integrated and robust power management solutions for automotive applications. The PMICs support comprehensive power supply for the system by a small form factor.
Check Infineon‘s automotive PMIC family OPTIREGTM portfolio providing integrated, multi-rail power supply solutions especially in the segments chassis, safety, powertrain, and electrical drive train.
The former Cypress’ solution portfolio complements our automotive MCU family and provides comprehensive power supply by a small form factor. Boost function integrated in the PMICs avoids system blackout under extreme battery voltage fluctuations. Low quiescent current of the PMICs reduce standby current of always-on functions. The PMICs comply with AEC-Q100, and rich system safety functions help to comply with modern vehicle ECU requirements.
S6BP20x series (S6BP201A, S6BP202A, and S6BP203A) PMICs are automotive grade, one-channel buck-boost DC/DC converters for automotive and industrial applications. They are ideal for automotive applications such as Body Control modules, Instrument Clusters, and ADAS. These PMICs have low standby current, and provide stable power output across a wide range of input voltages.
