The bqTINY series are highly integrated Li-Ion and Li-Pol linear charge management devices targeted at space limited portable applications.
The bqTINY series are highly integrated Li-Ion and Li-Pol linear charge management devices targeted at space-limited portable applications. These devices offer integrated power FETs and current sensors, reverse blocking protection, high accuracy current and voltage regulation, charge status indicators, and charge termination in a small 3 mm x 3 mm MLP (QFN) package. They are ideal for low-dropout designs for single-cell Li-Ion or Li-Pol packs.
