PMIC - Battery Chargers

The ISL6258AHRTZ is an integrated circuit electronic component designed for battery charging applications. This component is a single-channel, high-efficiency, synchronized switching boost converter that can regulate input voltage from 4.5V to 20V. It was designed specifically to allow for fast charging of both lead-acid and lithium-ion batteries and is extremely energy-efficient with a power conversion efficiency greater than 90%.

Application Field

The ISL6258AHRTZ is used in electrical applications which require the charging of multiple battery types. It is compatible with lead-acid, lithium-ion and nickel-metal hydride batteries, along with any other type of battery cell with a voltage of between 4.5 and 20 volts. The component is most commonly used in portable devices and those applications requiring fast-charging, such as electric and hybrid vehicles, medical and military equipment, and computers.

Working Principle

The ISL6258AHRTZ operates by using a synchronous boost converter to protect the battery and regulate the charge. The component contains an internal power MOSFET and current sense circuitry which allows the chip to constantly monitor and adjust the energy delivered to the battery. This is done by measuring the voltage across the inductor and comparing it to the battery voltage. The component then dynamically adjusts to account for changing environmental conditions, such as temperature, and optimizes for the fastest possible charging time.

The component also offers several advanced features, such as built-in voltage, current and temperature protection, over-voltage protection, short-circuit protection, under-voltage lockout protection and reverse current protection. Additionally, the component is capable of compensating for both low and high-temperature charging scenarios, ensuring optimal performance and maximum battery life.

The ISL6258AHRTZ is an ideal component for charging applications, offering high power conversion efficiency, advanced safety features and operation in a wide variety of environmental conditions. This makes it suitable for a range of battery charging applications and electric vehicle solutions.
