- DESCRIPTION
- The AIC6511 is highly integrated Li-ion and Li-Pol switching charge devices targeted at space limited portable applications. It offers integrated power MOSFETs, reverse blocking protection, high accuracy current and voltage regulation, charge status, and charge termination, in a small package.
The AIC6511 regulates the charge current and bat-tery voltage using two control loops to realize highly accurate constant-current charge and con-stant-voltage charge. A 100% duty cycle can be achieved when battery voltage is close to the input voltage due to the high-side P-Channel MOSFET.
In addition to the standard features, AIC6511 offers a multitude of additional features. These include temperature-sensing input for detecting hot or cold battery packs and programmable safety timer.
