ISL9211IRU68XZ-T

Power Management Integrated Circuits (PMICs) are designed to manage the distributions of the power within electric and electronic systems. PMICs are used to provide power supply, memory and storage, signal conditioning, mixed-signal functions, motor control, and comprehensive power optimization. There are many different types of PMICs, such as battery management and advanced power modules. The ISL9211IRU68XZ-T is a type of PMIC for Battery Management.

ISL9211IRU68XZ-T Application Field

The ISL9211IRU68XZ-T is an ultra-low quiescent current synchronous buck regulator. It is designed to Power System-on-Chip (SoC) applications, offering both lower cost and higher accuracy performance compared to other PMICs. It is also suitable for industrial, consumer and data processing applications. The ISL9211IRU68XZ-T features an input voltage range of 4V to 21V, as well as an adjustable output voltage range of 0.7V to 3.2V. The device features an adjustable switching frequency of 300kHz to 4MHz and can deliver up to 4A of continuous current. The device also provides protection features such as UVLO and thermal warning and shutdown.

ISL9211IRU68XZ-T Working Principle

The ISL9211IRU68XZ-T functions by converting a high input voltage range of 4V to 21V into a low adjusted output voltage range of 0.7V to 3.2V. The device is controlled using the PWM pin, and the output is regulated using an internal error amplifier, current sense and loop compensator. The device can deliver up to 4A of continuous current, and the switching frequency is adjustable from 300kHz to 4MHz. The device also includes a power-on-reset (POR) circuit, which monitors the system power supply, initiating a reset and/or shut down when the supply falls below the programmed POR threshold.

The ISL9211IRU68XZ-T also features a number of protection features, such as under voltage lockout (UVLO), soft start, and thermal warning and shutdown. The UVLO protection prevents a low voltage supply from damaging the system, while the soft start feature allows the regulator to start up gradually. The thermal warning and shutdown features provide thermal regulation, protecting the IC from damage due to high temperature.

The ISL9211IRU68XZ-T combines low power consumption and high accuracy performance to provide efficient power solutions for SoC applications. It is suitable for industrial, consumer, and data processing applications, with an input voltage range of 4V to 21V and an adjustable output voltage range of 0.7V to 3.2V. The device also offers up to 4A of continuous current, adjustable switching frequency of 300kHz to 4MHz, and a number of protection features.
