The ISL6251HAZ is a Prime Cell Li-Ion/Li-Polymer Battery Charger IC that integrates multiple high performance power elements—including power MOSFETs, current sense amplifiers and a Charge Curation Control (CCC) engine. It is designed to simplify circuit design and reduce BOM count for entry- level Li-Ion and Li-Polymer battery charger designs with various Input Sources.

The ISL6251HAZ battery charger is part of a family of ICs used in the power management industry for battery charging applications. It allows entry-level battery chargers to be designed quickly and efficiently. It has been designed to meet the highest standards in function, quality, performance and ease of integration.

The ISL6251HAZ Battery Charger IC is available in two versions: a Dual Channel version (DC) and a Single Channel version (SC). The Dual Channel version supports dual battery charging, while the Single Channel version supports single battery charging. The ISL6251HAZ ICs offer low power dissipation and a feature set that is tailored to battery charging applications.

The ISL6251HAZ uses an advanced Charge Curation Control (CCC) engine for improved charge acceptance and thermal stability. The CCC engine controls the charging and discharging currents of the battery and provides improved performance compared to conventional charge control methods. The CCC engine also helps to prevent overcharging and cell imbalance by monitoring the voltage of each cell. Additionally, the CCC engine can optionally provide temperature control to protect the battery from excessive temperature.

The ISL6251HAZ offers a range of features designed for battery charging applications. These features include: adjustable charge current, adjustable charge voltage, overvoltage protection, overdischarge protection, and an integrated charge status indicator. Additionally, the ISL6251HAZ supports two programmable safety timers, which can be used to monitor the battery temperature or to shutdown the charger if the charging process is not completed within the specified time.

The ISL6251HAZ is powered by an internal linear charge controller. This allows the IC to be powered from a wide range of input sources, including USB power sources, wall chargers and automotive power sources. The charge controller is designed to provide the highest level of efficiency, allowing the IC to operate at lower power levels and reducing power consumption and heat dissipation.

The ISL6251HAZ is a highly efficient battery charger IC, capable of supporting a wide variety of charging applications. The integrated CCC engine and safety timers increase the level of safety and reliability, while the adjustable charge current and voltage provide flexibility in meeting application requirements. The ISL6251HAZ is ideal for entry-level Li-Ion and Li-Polymer battery charging applications.
