The HP4059D6-42Y with TDFN-6L(1x1) Battery Management ICs ROHS manufactured by Hypower Microelectronics is a fully integrated power management and charging system that is specifically designed for protection, charge, and management of battery packs used in mobile and portable computing devices. It integrates a variety of battery protection, charge, and management functions, such as over-voltage, over-charge, over-discharge, over-temperature, and charge-detection. The device utilizes a Charge Control FET that provides the primary protection, and ensures that multiple battery chemistries (Li-ion, Li-polymer, NiMH, and LiFePO4) can be used in a single design. This device also supports a multitude of communication protocol between the host device and the pack. With its low power operation, fast response times, and a built-in high accuracy analog-to-digital converter - the HP4059D6-42Y provides a complete solution for system designers that meet the stringent requirements of the space limited designs in mobile and portable computing devices.
