Modern battery-powered electronic devices are becoming increasingly popular, and the accompanying battery management and power management functions associated with their operation can be complicated. To address this challenge, Monolithic Power Systems (MPS) developed the BQ2060ADBQ, a 5-channel series Linear Integrated Circuit (IC) for battery management in mobile applications and consumer electronics. This IC provides an integrated PMIC (producing multiple regulated and adjustable DC voltages) combined with multiple charging functions. The BQ2060ADBQ is also capable of providing an adjustable reference range of 0.8V to 4.255V. Its applications range from batteries and voltage regulators in mobile phones, digital cameras and portable audio players, to automotive power management systems.

The BQ2060ADBQ behaves as a total system solution to accurately manage a single cell Li-Ion or Li-Polymer battery with one sense resistor and a temperature sensor. The device electronics are powered from an external power supply, and include an analog/digital controller as well as other digital logic circuitry. The internal circuitry of the BQ2060ADBQ consists of two DC-DC converters, an LED drive circuit, two low-noise regulators, an on-chip analog current monitor (ACM), and a temperature sensor. The device also includes two charge regulators, one for NiMH/NiCd cells and one for Li-Ion/Li-Polymer cells.

The BQ2060ADBQ is a five-channel Battery Management IC that is designed to manage a battery-based system, providing several key features such as charge and discharge control, battery voltage monitoring, optimized power consumption, and accurate battery temperature monitoring. The device also offers optional low voltage cut-off protection, charge current control, and charge current monitoring. The chip also supports energy storage by allowing for rapid charging of the battery, as well as temperature and voltage monitoring.

When the BQ2060ADBQ is employed in battery management, it will primarily be handling the monitoring of the voltage, temperature, and current of the battery. The voltage can be monitored either through direct communication with the battery’s terminals, or through the device’s DC-DC converter. The device can also be used to monitor the temperature of the battery, either directly through contact with the battery or via a remote temperature sensor; this is particularly beneficial as overheating can lead to decreased performance or even battery failure. The BQ2060ADBQ also offers current monitoring, which enables the detection of low or high charge current and helps in preventing overcharging.

In summary, the BQ2060ADBQ is an ideal approach for battery management in mobile applications and consumer electronics. Due to its integrated PMIC and multiple charging functions, it provides a reliable and cost-effective solution for Li-Ion and Li-Polymer batteries. It provides accurate monitoring of the battery’s voltage, temperature, and current, as well as optional charge current control and low voltage cut-off protection, allowing for improved performance and battery longevity. The BQ2060ADBQ offers the convenience of an all-in-one solution suitable for a variety of applications, making it an optimal choice for battery management.
