ISL6257HRZ-T is a battery charger manufactured by Intersil. It is specifically designed for use in portable consumer applications where efficient battery charging is required. The ISL6257HRZ-T is part of Intersil\'s XHZ-T family of PMICs and battery chargers, which combine high current battery charging and system protection into a single IC. The ISL6257HRZ-T is designed to charge single cell Li-Ion batteries (3.2 to 4.3V). The ISL6257HRZ-T operates from an input voltage range of 4.6 to 32V and is able to support up to 1.5A of fast charging current. It utilizes an analog current-limited control circuit to regulate the output current and provide protection from short-circuits, input under voltage and thermal overload. The ISL6257HRZ-T also features programmable charge termination and a Charge Termination LED output.

The ISL6257HRZ-T allows for fast and controlled charging of batteries with a wide variety of use cases. It can be used for cell phones, tablets and other portable consumer devices, or in industrial and medical design suites. The wide range of supported input voltages and high charging current makes the ISL6257HRZ-T suitable for a variety of applications, including power tools, unmanned vehicles, medical equipment and instrumentation.

The ISL6257HRZ-T\'s working principle is based on an analog current-limited control circuit. This circuit uses feedback from an internal current sense resistor to regulate the output current and provide protection from short-circuits, input under voltage, and thermal overload. The circuit also contains a programmable termination timer, which is used to set the charge termination threshold. When the battery is charged to the termination voltage, the ISL6257HRZ-T will enter a sleep mode and shut off the charge cycle.

The ISL6257HRZ-T contains a Charge Termination LED output, which is used to signal the charge termination status. Additionally, the ISL6257HRZ-T can be configured to operate without the LED output in order to minimize the power consumption of the finished device.

The ISL6257HRZ-T is a versatile and efficient battery charger that is designed forefficient and fast battery charging, providing high current battery charging and system protection. The ISL6257HRZ-T is a great choice for a variety of portable consumer applications where efficient and sustained battery power is required.
