Power Management Integrated Circuits (PMICs) are semiconductor devices designed to provide constant power to semiconductor devices for extended periods of time without sacrificing performance or efficiency. PMICs (sometimes referred to as Battery Management ICs) are used in almost every electronic device today. They are used to manage power consumption, regulate the supply of power, and keep the battery levels in check. The HPA02135DBTR is a type of PMIC, specifically a battery management IC.

Application Field of the HPA02135DBTR

The HPA02135DBTR is a battery charging and monitoring IC used in portable applications. It is designed to provide fast and safe charging of lithium-ion rechargeable batteries, as well as monitoring their usage and performance. The IC is optimized for 4.2V Li-ion batteries, and is designed for highly integrated portable products such as mobile phones and laptops.

The HPA02135DBTR supports overvoltage and over-discharge protection, thus protecting the battery from potential damage in the event of sudden power surges or sudden power outages. This feature is especially important in cases where the device must remain powered for an extended period of time, or in cases where power surges are common.

The HPA02135DBTR also supports a fast charging mode, which is designed to conserve available energy by charging at a higher rate without risking damage to the battery. This feature makes it ideal for devices that must be charged quickly, such as smartphones.

Other features of the HPA02135DBTR include a pulse charging mode, automatic detection of battery charging status, and a power-saving mode. All of these features are designed to provide a more efficient, optimized battery charging solution for mobile device users.

Working Principle of the HPA02135DBTR

The HPA02135DBTR works by monitoring the current and voltage of the battery, and regulating the charging process accordingly. It features an on-chip current sensing amplifier and voltage comparator, which are used to monitor the battery’s charge state. When the battery’s voltage drops below the preset threshold, the IC will automatically start the charging process. The current or voltage of the battery is then monitored and adjusted according to the predetermined parameters. Once the charging process is completed, the IC will automatically switch off and conserve the available power.

The HPA02135DBTR also monitors the temperature of the battery, and will shut down the charging process if it detects a dangerously high temperature. This feature helps to protect the battery from potential damage caused by heat. The IC also supports overvoltage protection, which prevents the battery from being overcharged and damaged due to an excessive voltage.

The HPA02135DBTR also supports a power-saving mode which allows the device to conserve energy by reducing the current flowing through the battery and preventing unnecessary drain on the battery. This feature is especially helpful in applications where the device must remain powered for an extended period of time such as a laptop.

Overall, the HPA02135DBTR is an efficient and reliable battery charger and monitor, and is perfect for use in mobile devices and other portable products. It offers advanced features such as overvoltage and temperature protection, pulse charging mode, and a power-saving mode which make it a great choice for mobile device users.
