The HY2213 series, developed and manufactured by HYCON Technology Corp., presents a high-precision, energy-efficient battery charge balance integrated circuit (IC) specifically designed for single-cell lithium-ion or lithium-polymer batteries. This component encompasses a wide range of features tailored for multi-cell Li-ion rechargeable battery packs applications, including a high-precision voltage detection circuit capable of monitoring overcharge situations with a detection voltage range between 4.000V and 4.500V. Its unique design allows for delay times generated internally, eliminating the need for external capacitors and reducing the overall component count. Operating with a remarkably low consumption current in both operation (Typ. value 2.5uA, Max. value 3.5uA at VDD=3.9V) and standby modes (Max. value 0.5uA at VDD=2.7V), the HY2213 series is designed for energy-sensitive applications. It also offers versatility in operation temperature, ranging from -40℃ to +85℃, and comes in a compact SOT-23-6 package, making it suitable for space-constrained applications. The HY2213 series underscores HYCON Technology Corp.'s commitment to advancing battery management solutions by integrating overcharge detection and release, standby detection, and charge balance functionality into a single, efficient, and easy-to-use IC.

The DW01B, a lithium-ion/polymer battery protection IC, is engineered for safeguarding single-cell lithium-ion/polymer batteries in compact electronics, such as cellular phones, against risks including over-charge, over-discharge, and over-current conditions. This component's functionality enhances the longevity and reliability of battery-powered devices by preventing instances that could otherwise compromise battery health. With its ultra-small SOT-23-6 package, the DW01B facilitates integration into space-constrained battery packs. Highlight features include an ultra-low quiescent current of 2μA at 3.5V supply voltage, precise overcharge protection voltage at 4.30V ± 50mV, and over-discharge protection voltage set between 2.50V ± 75mV. Additionally, the IC features over-current protection with two levels of detection, a broad -40°C to +85°C operating temperature range, and requires minimal external components for operation. The DW01B's low standby current drain and accurate detection voltages ensure the safe and efficient management of battery charging and discharging processes, making it an essential component for developers aiming to optimize the performance and safety of portable electronic devices.
