Power management integration circui t (PMIC) are electronically control led devices with integrated circuitls that regulate, control and monitor the electric power supply for the electronic systems for which they are designed. One of the common applications for PMIC is to manage the electric power sources used for charging batteries and also to deliver the battery current to other electronic system components. The BQ24165YFFT battery charger belongs to the series of PMICs produced by Texas Instruments. It is specially designed for USB, lithium-ion and multimode charging applications.

The BQ24165YFFT battery charger IC is designed to support two-cell lithium-ion batteries. The input voltage range for this battery charger is 2.7V–5.5V. It has a current limit of 2A. This IC also offers protection against over-voltage, over-current, and over-temperature. Another feature of the BQ24165YFFT is its integrated PowerPath™ technology, which ensures the battery is charged and protected, even when the charger is connected. The BQ24165YFFT also incorporates a configurable power path that supports both low power source applications and high power applications.

The BQ24165YFFT is ideal for applications such as calculators, medical devices, handheld data loggers, security systems, and portable consumer electronics. It is also ideal for applications such as netbooks, tablets, ultrabooks, and other consumer electronics with advanced battery management systems.

The BQ24165YFFT battery charger works by utilizing MOSFETs and synchronous rectification to regulate the operation of the charger. The MOSFETs are used to regulate the voltage and current supplied to the battery. The synchronous rectification ensures that the current supplied to the battery is as efficient as possible. The BQ24165YFFT also includes a voltage regulator to ensure that the output voltage from the charger is kept within the specified voltage range. It also incorporates a low battery monitoring circuit that is used to monitor the battery voltage and disconnect the charger from the battery when the voltage drops too low.

The BQ24165YFFT battery charger also includes a limited power savings mode. This mode is used for applications where the battery power needs to be conserved and regulated. The limited power savings mode helps to reduce the amount of charge cycles and losses due to status inefficiencies. The limited power savings mode helps to regulate the charging and discharging of the battery so that it can be used in the most efficient way.

The BQ24165YFFT battery charger also incorporates a sleep mode. This mode is used in applications where the battery needs to be charged and disconnected intermittently. The sleep mode allows the charger to be turned off and then turned back on automatically when a charge cycle is required. This helps to reduce the power consumption of the battery while not actively charging or discharging.

Overall, the BQ24165YFFT battery charger is a highly efficient and feature-rich device that provides robust charging and power management for a wide variety of battery-powered applications. Its features, such as the integrated PowerPath™ technology, the limited power savings mode, and the sleep mode make it suitable for a variety of battery-powered applications. With its broad range of features and its high level of efficiency, the BQ24165YFFT is an ideal choice for applications that require reliable and efficient battery charging solutions.
