The BQ24901PW battery charger is a single-cell lithium-ion/polymer battery charger with integrated current sensing and temperature monitoring. It has a 4.2V regulated charge voltage and two independent charge current sources, one of which is adjustable. It is a fully integrated, low-cost solution for single-cell portable charger designs.

The BQ24901PW charger is designed to cost-effectively charge single-cell Li-ion/Li-polymer batteries. It includes a wide input voltage range, adjustable charge current sources and integrated current-sense circuits and temperature monitoring. This charger is capable of charging battery cells with a minimum voltage of 3.4V and a maximum voltage of 4.2V.

The BQ24901PW provides two independent current sources, one of which is adjustable. This adjustable current source is referred to as the ICHG-ADJ and is internally limited to 1A with a maximum over-current protection of 1.2A. The ICHG pins are used to control the adjustable current source and it is also used to sense the voltage across the series resistance. This charge current source is used to charge the cell until it reaches the Factory Set Maximum Charge Current (FSCC) level.

The BQ24901PW includes integrated temperature monitoring and current-sense circuits. The temperature monitoring circuit is used to protect the device and battery from overtemperature conditions. The current sensing circuit is used to monitor the charge and discharge current of the battery to determine the charge profile. This capability provides an advantage over other chargers that do not have integrated current sensing.

The BQ24901PW is designed to be used in a variety of single-cell battery charger applications. It can be used in consumer electronics, medical devices, and automotive applications. The device can be used to charge any single-cell Li-ion/Li-polymer battery with a maximum voltage of 4.2V. This charger is also capable of being used in portable electronic devices such as cellular phones, tablets, and portable media players.

The BQ24901PW battery charger works by monitoring the voltage and current at the battery terminals. The device automatically detects the presence of a battery and begins charging the battery at a predetermined rate. The adjustable current source is used to charge the battery until it reaches the preset maximum charge current. Once the preset maximum charge current is reached, the charger transitions to a constant voltage mode and regulates the current at the predetermined maximum. The device is also capable of monitoring the temperature of the battery to protect the battery and device from over-temperature conditions.

The BQ24901PW is an ideal solution for single-cell batteries in a wide variety of applications. It has integrated current sensing and temperature monitoring and is capable of charging any single-cell Li-ion/Li-polymer battery with a maximum voltage of 4.2V. This charger is well-suited for consumer electronics, medical devices, and automotive applications.
