CHY103D-TL is an accurate low quiescent current linear Li-Ion battery charger and PowerPath manager that can efficiently charge one or more cells of Li-Ion batteries with a minimum current of 0.1mA. The device integrates smart features such as a dynamic power path management system, short-circuit protection, overvoltage protection, reverse current protection, over-temperature protection, and LED dimming. This makes the device well-suited for a variety of applications such as consumer electronics, home automation, automotive and industrial applications. In this article, we will discuss the application field and working principle of CHY103D-TL.

The CHY103D-TL is ideal for use in consumer electronics, home automation, automotive, and industrial applications due its dynamic power path management system and wide operating temperature range. It can deliver up to 1.8A in charge current and maintain a Linearity of 0.2%. This makes it proficient in delivering a constant power supply to various electronic devices. It also features short-circuit protection, overcharge protection, reverse current protection, over-temperature protection, and LED dimming, making it perfect for a wide range of applications.

The working principle of CHY103D-TL is based on the principle of power management. The device monitors and manages the input power required for charging the battery. It also monitors the battery voltage, temperature, and current, to protect the battery from overcharging, thermal runaway and other faults that could cause damage to the battery. The device also features a dynamic power path management system that intelligently switches between the power input and the battery, in case of low battery voltage or no power input.

The CHY103D-TL also features a programmable charge current limit, enabling the user to adjust the maximum current setting. This ensures that the battery is charged safely up to its full potential, while still minimizing the risk of overcharge. In addition, the device also has a low quiescent current linear charger that efficiently charges the battery with a minimum current of 0.1mA. This ensures that the battery is charged with a very low current, preventing any damage to the battery due to overcharging.

The CHY103D-TL is also capable of providing LED dimming control. The device automatically adjusts the LED brightness, depending on the battery level, ensuring that the LED is always at the optimal brightness. Finally, the device is equipped with over-temperature protection, and a temperature sensor that allows the device to detect if the battery is over-heating and shut off power to the battery if the temperature rises beyond a set limit.

In conclusion, the CHY103D-TL is an advanced low quiescent current linear Li-Ion battery charger and PowerPath manager. Its dynamic power path management system, short-circuit protection, overcharge protection, reverse current protection, over-temperature protection, and LED dimming makes it an ideal choice for applications such as consumer electronics, home automation, automotive and industrial applications. The device is capable of charging Li-Ion batteries with a minimum current of 0.1mA, while maintaining a linear charging profile and providing power backup in case of low battery voltage or an unexpected power outage.
