PMIC - Battery Chargers are used in a variety of applications, providing an efficient and reliable way of charging cells. The BQ24232HARGTR integrated circuit is one such example, designed to charge a diverse range of battery chemistries. This article will discuss the BQ24232HARGTR’s application field and working principle.

Features

The BQ24232HARGTR is designed for charging portable consumer applications that require a wide range of battery chemistries such as Li-Ion and Li-Polymer. It incorporates a highly integrated charging solution that offers protection from overcharging, over-discharging and short-circuiting. In addition, the product offers a unique feature set that includes programmable charge current and charge termination thresholds making it suitable for a wide range of portable consumer electronic devices.

The device also offers a number of features that make it suitable for use in other applications such as automotive and industrial. These include the capability to monitor battery and system conditions and respond to them, as well as support for multiple input and output voltage ranges. This makes the BQ24232HARGTR a versatile and reliable solution for charging batteries.

Working Principle

The BQ24232HARGTR uses a constant-current – constant-voltage (CC-CV) charging technique to charge batteries. Under this technique, the charging current is kept constant until the battery is brought to the set charge voltage. At this point, the voltage is maintained at the set point and the charging current is reduced to prevent overcharging. At the same time, protection mechanisms monitor the battery parameters and respond to any faults that could result from incorrect operation.

The charging current can be programmed using the integrated interface, allowing the user to adjust the amount of current to suit the specific application. Once the desired level is reached, the device will switch over to a constant-voltage mode and begin charging the battery. This ensures the battery is charged effectively and protected against any potential faults.

The BQ24232HARGTR also incorporates a unique standby mode that allows the application to enter an active state when required. This feature prevents the charger from drawing current unnecessarily when not in use. This improves the overall efficiency and reduces power consumption, allowing the battery to be used for longer.

Conclusion

The BQ24232HARGTR integrated circuit is a versatile and reliable solution for charging batteries. It is designed for a wide range of applications and provides a highly integrated charging solution with a number of safety and efficiency features. The device offers a constant-current – constant-voltage charging technique that ensures batteries are safely and efficiently charged. The device also supports multiple input and output voltages, making it suitable for a wide range of consumer and industrial applications.
