PS8A0086PEX

The PS8A0086PEX is a power management integrated circuit (PMIC) and the latest addition to the Power Management Specialized (PMS) portfolio. This PMIC offers reliable and efficient control of power on multiple nodes in portable applications, specifically in smart phones, tablets, and portable media players. Its package size is as small as 1.2mm x 1mm and can be combined with other PMICs to offer complete multi-node power management solutions. The PS8A0086PEX can be used for the direct switching of loads in a variety of applications, including battery chargers, wireless charging, hot plugging, and thermal management. It provides dual channel power switching with high-side and low-side N-channel MOSFETs and is designed for P-channel driven loads such as voltage regulator modules (VRMs). The device also offers low-power start-up, over-voltage protection, and over-current protection for improved system efficiency and reliability. The PS8A0086PEX utilizes a simple architecture that combines a synchronous Buck regulator and an efficiency-optimized low-dropout (LDO) linear regulator in a single integrated circuit. The Buck regulator allows for the efficient generation of output voltages up to 5V, while the LDO regulator provides additional current with output voltages up to 3.3V. The integrated synchronous rectifier, switching FETs, and comparator circuitry allows the device to operate up to 10MHz and provide a very high level of efficiency. The PS8A0086PEX also offers several features to help improve system reliability and safety. It includes an integrated power-on reset circuit that is activated whenever the input supply voltage (VDDIN) drops below the internal reset threshold. This helps to ensure a safe reboot of the system in case of an over-voltage or over-current fault. The device also includes an enable input that can be used to enable or disable the the power switching circuitry independently. This allows for the safe disconnection of the load in case of a fault. In addition, the PS8A0086PEX includes short-circuit protection and thermal protection, both of which can help to ensure that the device does not operate outside of its safe operating range. The device also has an on-board voltage detector and comparator that provides system integrity monitoring and allows the detection of out-of-regulation conditions. The PS8A0086PEX offers a fully featured and highly efficient solution for power management in compact portable applications. It offers low standby current consumption and is capable of delivering high output currents in a small form factor. This makes it an ideal solution for applications such as smart phones, tablets, and portable media players.
