PMIC - Battery Chargers

Batteries are a staple of many of today’s electronic devices. It’s important to have the right charging technology so that these batteries operate at the peak of their performance potential. PMIC – Battery Chargers are the latest and most advanced charging system available on the market, and their application can be incredibly beneficial to electronic device design.

One of the most advanced PMIC – Battery Chargers on the market today is the BQ24070RHLRG4. This charger is designed to be used with small, single-cell lithium ion batteries, like those found in digital cameras, mobile phones, music players, and other small devices.

Application of BQ24070RHLRG4

The BQ24070RHLRG4 is designed for applications where a 4-cell battery management system is needed. The primary application for this device is for single-cell lithium ion battery charging and management. With this charging system, the use of a single-cell battery is easier and more efficient, because the system controls the entire charging process. This includes detection of an empty battery, charging, cell balancing, low voltage protection and over-charge protection.

This device also offers quicker charging than other conventional charging structures. The BQ24070RHLRG4 is powered by a DC wall adapter and it is capable of delivering up to 1A of current to recharge the battery, which is one of the highest charging levels available on the market.

Working Principle of BQ24070RHLRG4

The BQ24070RHLRG4 works in a very simple way. It applies a predefined voltage to the battery and then monitors the battery’s charge rate. As the charge rate drops, the device adjusts the voltage, so that the charging rate is kept constant. This helps prevent overcharging, which can be damaging to the battery.

The device also has integrated over-voltage protection, which prevents the battery from being charged too high. This is an important feature because charging the battery too high can cause serious damage. The over-voltage protection circuit is designed to intervene and stop charging the battery when it reaches its maximum charge level. This helps to ensure that the battery does not become overcharged and damaged.

The BQ24070RHLRG4 also has an integrated battery temperature monitoring feature. This feature monitors the battery temperature and will stop charging if it gets too hot. This helps to prevent overcharging and reduces the risk of damaging the battery.

The last feature of the BQ24070RHLRG4 is its dual-mode operation. In dual-mode, the device will charge both a 4-cell battery and a single-cell battery, which makes it perfect for applications where multiple batteries are used.

Conclusion

The BQ24070RHLRG4 is a state-of-the-art PMIC – Battery Charger that is perfect for applications where a 4-cell battery management system is needed. With its integrated over-voltage protection, temperature monitoring, and dual-mode operation, the BQ24070RHLRG4 is one of the most advanced battery charging systems on the market.
