The MC34674CEPR2 is a three-phase power management and battery charging integrated circuit specifically designed for Li-Ion and Li-Po (Polymer) battery packs. It is specifically designed for use in smart phones, tablets, wearables, IoT devices and other battery-powered applications. The MC34674CEPR2 offers a range of features and benefits to ensure that your application runs optimally.

The MC34674CEPR2 offers a comprehensive range of power management and battery charging capabilities. It can efficiently manage up to 3-series Li-Ion or Li-Po (Polymer) battery packs, with an input voltage range of 2.0V - 20V. It takes a wide range of input voltage and current levels and deliver current up to 2.5A per phase. The MC34674CEPR2 is a highly efficient, four-phase buck converter that provides up to 2.5A of output current per phase. It is also capable of providing up to 14.25A of total system load current.

The MC34674CEPR2 includes a variety of features to manage the overall power needs of your application and battery system. It features an efficient, three-phase power-stage architecture which works in unison with the battery charger state machine and advanced monitoring capabilities. This ensures that the battery system is always operating in the most efficient manner and keeps you informed of the battery system\'s status. Additionally, the MC34674CEPR2 provides two on-chip regulators which support low-voltage and audio amplifier system designs.

The battery charger state machine on the MC34674CEPR2 is designed to detect battery charging conditions and initiate charging automatically. It can also detect when the battery is fully charged and shut down the charger in order to protect the battery from overcharging. The charger state machine also monitors the battery voltage to detect when the battery is low and initiate a boost phase in order to get the battery back up to its ideal voltage. During the three-phase buck converter powerstage operation, the charger state machine can detect any short circuit or overvoltage conditions and quickly shut down the powerstage to prevent any damage.

The MC34674CEPR2 integrates a highly efficient step-down DC/DC power conversion feature. The step-down feature reduces the input voltage level to a required downstream voltage level and enables the delivery of the desired current. The integrated step-down DC/DC power conversion feature works seamlessly with the battery charger state machine and advanced monitoring capabilities to keep your application and battery system efficient.
