Power Management Integrated Circuit (PMIC) contains circuit, regulations, protection and control capabilities all in one single chip. It is has become increasingly sophisticated and versatile as the industry in electronic and battery technologies progresses. A leading PMIC manufacturer of today, Linear Technology, produces the LTC4097EDDB#TRPBF dual high-side switch battery chargers. This chip is designed to provide enhanced power management and charging within portable systems.

The LTC4097EDDB#TRPBF is designed to be used as dual high-side switch battery chargers with protection features for battery-powered applications. It features two independent hi-side switches with up to 5A of output current and low-side load switches, both enabled by the internal current limit. These switches are ideal for charging two cells in series, providing power for two distinct loads, two batteries of different chemistries, or a single battery with two outputs. Low-side switches can be independently soft-started from the high-side and the loads can be operated in parallel, allowing for greater versatility in the system\'s operation.

The LTC4097EDDB#TRPBF includes 1.25V adjustable over voltage protection, 0.3V under voltage lockout, thermal protection, and other important safety features for battery protection. In addition, the chip features an open drain START/STATUS pin that indicates the current state of the high-side switch, acting as both an input and output pin. This pin can also be used to latch the high-side switch off, which is useful during software-defined charging. The chip can easily adapt to a wide range of battery chemistries, including Li-Ion, Li-Poly, LiFePO4, and alkaline batteries, making it an ideal choice for consumer electronics, industrial, and energy harvesting applications.

The LTC4097EDDB#TRPBF offers a wide range of features and capabilities for battery charging, power management, and protection. It is highly efficient, with up to 90% power conversion efficiency and up to 1MHz of operating frequency. It also includes shutdown, low-battery detect, power-up, over-current and over-temperature protection, and a fast programmable soft-start circuit.

The LTC4097EDDB#TRPBF is a versatile chip offering an attractive combination of features for battery-based applications. It is an efficient, reliable, and cost-effective solution for powering portable systems. With its advanced features, the chip can significantly improve the performance, durability, and safety of battery-powered systems without increasing the system\'s complexity or cost.
