ISL6252AEVAL1Z

The ISL6252AEVAL1Z evaluation board is designed to demonstrate the power management features of the ISL6252AEVAL1Z chip. It consists of a board containing a 28-pin SOIC package and an onboard rechargeable battery. The board is intended for lab and classroom use, in the evaluation, demonstration and testing of the features of the ISL6252AEVAL1Z chip.

Application Field

The ISL6252AEVAL1Z evaluation board can be used for applications in communications equipment, portable device power supplies, controllers, regulators, automotive systems and power management related applications. It can also be used for testing the load sharing capability of the ISL6252AEVAL1Z, as well as for bench testing or evaluation in systems that require a stable output voltage.

Working Principle

The ISL6252AEVAL1Z is a dual-channel battery charger and power management IC that works according to the embedded charge-pump topology. This topology allows the chip to provide up to 7 A of current without any external components. It can also provide multiple voltage outputs with tight regulation accuracy using its internal DAC and feedback loops.

The ISL6252AEVAL1Z contains two power inputs, both of which can be used to charge Li-ion or nickel-cadmium batteries of varying sizes. While charging, the two channels can be used individually, or both can be connected in parallel to provide a higher current output. The on-board LED indicator indicates the charging status and shows when the battery is fully charged.

The ISL6252AEVAL1Z can also be used to control the power distribution between multiple power sources in a system. It utilizes an on-board analog-to-digital converter and feedback loop controlling mechanism to adjust the current and voltage of each channel, as well as the overall output power. This control mechanism allows the system to adapt to varying conditions and power needs. It also supports the ability to switch between different output voltages and currents to meet the varying needs of different systems.

The ISL6252AEVAL1Z evaluation board also contains a low-power low-dropout voltage regulator, allowing it to operate in battery-powered systems with input voltages as low as 1.8 V. This low input voltage is suitable for Li-ion or nickel-cadmium batteries, and also enables it to regulate the output voltage accurately in a wide operating temperature range.

In summary, the ISL6252AEVAL1Z evaluation board is a useful tool for the evaluation and demonstration of the features of the ISL6252AEVAL1Z chip. It can be used for a variety of applications in communications equipment, portable device power supplies, controllers, regulators, automotive systems and power management related applications. With its multiple power inputs, integrated analog-to-digital converter and feedback loop control mechanism, the evaluation board enables users to accurately control multiple channels of power and switch between different output voltages, making it an ideal choice for testing, evaluation and demonstration purposes.
