The BQ51013BRHLR is a comprehensive and integrated battery charging and management solution for single-cell lithium-ion and lithium-ion battery packs. This power management integrated circuit (PMIC) provides charging and protection of battery packs up to 5 cells and fully complies with the IEEE1725™ standard. It consists of a buck-boost (Buck/Boost) regulator, a battery safety monitor, and a battery gas gauge with support for the Maxim one-wire slave (1Wslave) communications interface.

The BQ51013BRHLR application field is for a variety of applications, including portable computing, tablets, notebooks and other mobile electronics requiring a reliable and safe charging source for battery packs. This power management integrated circuit is suitable for many types of battery technologies, including Ni-MH, NiCd, and Li-Ion, and it can deliver up to approximately 6A for two cells and up to approximately 12A for five cells of charging current.

The BQ51013BRHLR is designed to accommodate a wide range of applications from low-power to high-power with a high level of efficiency and protection. Its output voltage can range from 6V to 16V with an adjustable current limit up to 5A, allowing it to support a wide range of battery voltages and capacities. The Buck/Boost regulator also provides excellent line and load regulation as well as low EMI.

The BQ51013BRHLR includes an integrated battery safety monitor (BSM) to provide full protection against overcharge, over-temperature, short circuit, and cell imbalance. The BSM allows the user to configure the parameters required for system safety and includes an integrated overvoltage protection where the voltage is limited to the set threshold. The BQ51013BRHLR also includes an integrated battery gas gauge that interfaces with the Maxim 1Wslave protocol for wireless communication.

The BQ51013BRHLR also features an integrated power source selector with a USB/AC/DC port to allow for a wide variety of power sources. This allows the user to easily switch between power sources, making the device more versatile and allowing for improved system flexibility and efficiency. The BQ51013BRHLR also includes an integrated power switch controller and an over/Under voltage protection (OVP/UVP) circuit to allow the user to program and control the voltage at the load. The power switch controller also provides a low-power mode for energy savings.

To sum up, the BQ51013BRHLR power management integrated circuit is a comprehensive and integrated battery charging and management solution for single-cell lithium-ion and lithium-ion battery packs. With a wide range of features, the BQ51013BRHLR is suitable for applications from low-power to high-power providing high level efficiency and protection. Its integrated battery safety monitor ensures safety against overcharge, over-temperature, short circuit, and cell imbalance while the integrated power switch controller allows for low-power mode for energy savings. The BQ51013BRHLR also includes an integrated battery gas gauge that interfaces with the Maxim 1Wslave protocol for wireless communication allowing for improved system flexibility and efficiency.
