Introduction

The ISL6291-1CR is a power management integrated circuit (PMIC) containing a high-efficiency, full-featured battery charging controller. It is specifically designed to bring exceptional system level power management for applications such as smartphones, tablets, notebooks, and other portable devices.

Application Field

The ISL6291-1CR battery charger is ideal for applications that require a highly integrated, efficient and powerful battery charger. It is well suited for charging high-capacity batteries with a wide range of voltage and current levels, with the capability to recharge lithium-ion (Li-Ion) and nickel-cadmium (NiCd) batteries. The ISL6291-1CR also features multiple modes of operation, giving users the flexibility to charge their batteries as desired. The IC can be used on a wide range of applications, including portable computers and tablets, smartphones, Bluetooth accessories and other AC/DC powered devices.

Working Principle

The ISL6291-1CR uses a combination of buck-boost and linear regulators to precisely control the output from the battery charger. The USB port is the primary source of input power for the charger, which is then regulated and divided into two components, one for powering the IC itself, and one for charging the battery.The battery charger also supports a wide range of charging capacities. This allows users to easily adjust the charge rate from slow to fast, depending on the capacity of the battery being charged. The IC also includes a selectable charge termination feature to ensure that the battery stops charging at the optimal voltage and that the charging process is safe. Additional features of the IC include input over-voltage protection and battery temperature monitoring to prevent overcharging, and an adjustable over-voltage protection and reverse current protection circuit to prevent any damage to the battery during charging. Finally, the ISL6291-1CR supports current-based charging, which helps to reduce total charging time.

Conclusion

The ISL6291-1CR is a high-efficiency, full-featured battery charging controller specifically designed to bring exceptional power management for portable devices like smartphones and tablets. Through a combination of buck-boost and linear regulators, the IC can charge Li-ion and NiCd batteries with a wide range of voltage and current levels, with adjustable charge rates and current-based charging to reduce total charging time. The IC also offers multiple modes of operation, input over-voltage protection, battery temperature monitoring, and adjustable over-voltage and reverse current protection.
