Application Field

BQ24196RGET is an ideal battery charger in portable applications and devices, providing a wide range of features and options to suit diverse requirements. The primary applications of BQ24196RGET include digital cameras, video recorders, gaming devices, MP3 players, mobile phones, medical equipment, Notebooks, ultrabooks, tablets and so on. Additionally, BQ24196RGET is compatible with multiple battery chemistries, allowing it to be used in a wide variety of applications.

Working Principle

The BQ24196RGET integrates a controller, protection MOSFETs, power switching MOSFETs and a current sense resistor, to easily and efficiently manage the battery charging process. The Charger offers two selectable charge currents for the customer to choose in accordance with the battery size and capacity. During the battery charging process, the charger monitors the battery voltage, current, temperature and charge time. Once the current or voltage levels exceed their respective thresholds, or if the battery reaches the specified charge time, the charger begins to terminate the charge cycle.

The charger also employs a voltage sense mechanism to actively monitor the input current, providing a better means to regulate the charge current drawn from the wall adapter. Furthermore, the charger provides selectable levels of charge current as per the user requirements, offering higher flexibility and selection of charge current to accommodate a wide range of battery chemistries. Additionally, the charger can be partially enabled in order to limit current from the battery cells. This feature is especially useful in situations where multiple batteries are used in closely packed conditions.

Conclusion

BQ24196RGET is a comprehensive battery charger suitable for a wide variety of portable applications and devices. It features selectable charge currents, temperature sense, voltage sense and input current limitation to safely and efficiently manage the battery charging process. The BQ24196RGET is an excellent choice for efficient and reliable charge management in battery powered devices.
