Texas Instruments Integrated Circuits (ICs) - Power Management (PMIC) - Battery Chargers BQ25180YBGR

The BQ25180YBGR is a linear battery charger IC designed for single-cell applications, supporting a charging current of up to 1 A and system loads of up to 2.5 A. It operates within an input voltage range of 3.0 V to 5.9 V and is tolerant to input voltages up to 25 V. The device features configurable battery regulation voltage with 0.5% accuracy, adjustable fast charge current from 5 mA to 1 A, and configurable termination current down to 0.5 mA. This charger supports various charging profiles, including a standard Li-ion or LiFePO4 profile with precharge, constant current, and constant voltage phases. It includes advanced power path management, allowing for dynamic optimization of charging from weak adapters and the ability to select between adapter or battery power for the system. The BQ25180YBGR also integrates multiple fault protection features, including input overvoltage, battery undervoltage, and thermal regulation protections. The device is packaged in an 8-ball chipscale package, measuring 1.6 mm x 1.1 mm, which facilitates a compact design without the need for high-density interconnect (HDI) PCB processes, potentially reducing overall PCB costs. It is suitable for applications such as TWS headsets, smart glasses, smart watches, and various automation systems.
