Energy scarcity is an increasingly pressing issue for all nations, and advances in battery technology have been pivotal in discovering solutions. PMICs (Power Management Integrated Circuits) are required components in any electronic circuit that involves a battery, and the modern flexibility of these systems allows batteries to be charged, balanced, stored and monitored with the utmost efficiency and speed. The LC709203FQH-03TWG is one such powerful dedicated battery IC from SANYO, and gains significant attention in the battery management sector for its top-of-the-line performance.

The LC709203 amongst other PMIC’s is often regarded as an essential element in any rechargeable battery-powered product, and its popularity stems from its made-for-purpose design. With dedicated charge and discharge functions; robust thermal, over-current and reverse voltage protection; dynamic charging control; 4-cell Li-ion/ LiFePO4 battery compatibility; integrated self-resetting P-channel MOSFETs; and more — the LC709203 is perfect for any current battery-powered mobile device.

The LC709203FQH-03TWG is almost exclusively used in battery management systems due to its high performance and reliable output. It’s integrated serial communication enables easy coordination and synchronization with a system’s complex power requirements, and also gives rise to bi-directional management via a single bus. The device can accurately monitor the average battery current and its integrated temperature sensor allows advanced thermal protection and optimal charging points. The advanced onboard voltage regulation also allows quick and accurate charging of the connected Li-Ion/LiFePO4 batteries.

The working principle of the LC709203FQH-03TWG device is fairly simple. During charging, it allows the charge current to pass through its internal current-limiting circuit, where it is regulated and sent to the battery through its integrated self-resetting MOSFET. This MOSFET is designed to automatically switch off the control circuit in the case of an over-current fault or reversal of voltage. The regulation of charge is also done through the processor, and is set for optimal battery life and efficiency coinciding with the input/output settings. During discharge, the same MOSFET as with charging is automatically switched on and off, however, the discharging current is always limited to the value of the input current.

The features of the LC709203FQH-03TWG make it an extremely reliable and secure Power Management Integrated Circuit, and its application is beyond the scope of just the battery management industry; It is also useful in the electronics industry, as it makes it easier to manage power sources, reduce power losses and maximize battery performance. This device is highly recommended in any application that requires a safe, secure and reliable battery management system.
