PMIC - Battery chargers have gone through evolution and innovation since the nineties when the first big wall outlets started to appear on the market. Today we have battery chargers that are incredibly small, efficient and yet affordable. One such example is the MCP73838-FCI/UN battery charge controller. It is one of the most popular battery chargers available in the market today. The MCP73838-FCI/UN is a small, efficient battery charger designed to work in almost any application. Its small size and low cost make it ideal for portable devices such as smartphones and tablets.

The MCP73838-FCI/UN is an intelligent battery charge controller that is designed for small to medium size Li-Ion/Li-polymer batteries. The battery charger is designed to provide a constant voltage and current with features such as overcharge, over discharge and thermal protection for optimal battery performance and long life. It is a dual-channel battery charger controller that can be used with two cells in series or four cells in parallel. The charger also has an on-board resistor that can be used to set the current limits of each channel.

The MCP73838-FCI/UN integrates an advanced analog-to-digital converter (ADC) which provides an accurate and precise current and voltage feedback to the battery charger, allowing a precise current limit setting to optimize battery life. The battery charger also integrates a device temperature monitor which enables the charge controller to reduce the charging current when the temperature of the device is higher than the programmed thresholds. This enhances battery safety and extends the battery’s life.

The MCP73838-FCI/UN is powered by a 5V input source and can be used to charge up to two Li-Ion/Li-Polymer cells. The charge current is adjustable from 100 mA to 1.2 A and the charge voltage is set at the default of 4.2 V, but can be adjusted to 4.35V or 4.5V. The charge controller also provides an input current limit that is adjustable up to 1.5 A, and an input power limit of 7.5 watts. This allows the charge controller to be used with a wide range of power sources such as wall adapters, USB power, and car adaptors.

In terms of charging performance, the MCP73838-FCI/UN provides a fast and safe charging process, with a constant voltage and current that can be adjusted to suit the specific battery type. The charger also features pre-charge and post-charge protection to ensure safety and battery longevity. It also features several charging modes such as trickle charge, linear charge, fast charge, and soft start for different battery types.

The MCP73838-FCI/UN has many potential uses. It is an ideal solution for applications and embedded systems that require precise battery charging, such as wearables, IoT nodes, handhelds and portable devices. It can be used in a variety of charging scenarios such as wall mount, AC/DC, USB and car adaptors. Furthermore, the MCP73838-FCI/UN is an ideal choice for space-constrained designs as its small size allows it to be placed in almost any area.

In conclusion, the MCP73838-FCI/UN is an ideal choice for portable applications due to its small size, simple design, and efficient battery charging performance. Its advanced features such as overcharge, over discharge and thermal protection provide an extra level of safety for batteries. This makes it an ideal solution for many embedded applications that require precise and safe battery charging.
