The MC33FS6520CAER2 is a power manager integrated circuit from ON Semiconductor which provides multiple low-power functionality in a single device by controlling and monitoring several power paths and powering down for substantial power savings. It is a specialized PMIC and designed for use in system level applications in embedded systems, personal electronics, white goods, automotive and industrial applications.

The expression of the device’s power savings potential is the eSMI (Enhanced System Management Interface), a system management mode for applications that require more intelligent power management than most typical power management systems. The eSMI power management capability is enabled by the presence of a bidirectional I2C bus connection, allowing the device to be pre-programmed to automatically turn off its power paths if activity is not detected.

The device provides various current level settings, fault detect and protection, output monitoring, and phase change detection capabilities. It also has integrated over-voltage-protection (OVP) and over-current-protection (OCP) of power paths monitored by the three digital-power-switches (DPS1-DPS3) and the high-side-switch (HS). The three power paths are configured to with programmability of the current levels for each output by the existing external sense resistors.

The MC33FS6520CAER2 provides an industry-standard I2C interface that facilitates configuration, monitoring and control. Built-in phase-change-detection logic allows the device to monitor the topology of each phase, detect changes in phase configuration, and respond accordingly to ensure safe operation. It features programmable over/under-voltage settings and includes an OVP/OCP-compensation-mode (CPM).

The MC33FS6520CAER2 is a low-power, specialized PMIC designed for applications requiring system level power management and monitoring. It provides a comprehensive feature set with power savings potential, robust fault protection, and digital control of power paths with I2C interface. Its tight current monitoring, over/undervoltage detection, and phase change detection capabilities provide a high level of reliability. This device is suitable for embedded systems, personal electronics, white goods, automotive and industrial applications.
