該設備具有自動電源路徑控制。當輸入電源電壓可用時，所有電源都來自輸入。這包括從 LDO 和 SYS 引腳對電池充電和加載。當有效輸入電壓不可用且電池未耗盡時，設備切換到電池供電。MAS6260 包括電池過充、過放和過溫保護。此外，輸入 (VIN) 和兩個輸出 (SYS、LDO) 都有過流保護。在四種不同的故障條件下，設備會發(fā)出不同的故障條件信號。充電和關機模式由系統(tǒng)控制。在關斷模式下，電池電流消耗被最小化，以限度地延長電池壽命。MAS6260 采用小型 DFN-12 3.75 mm 封裝。

MAS6260 is a charger IC for single-cell Li-Ion and LiPo batteries. It includes 150mA low-dropout (LDO) regulator and protection functions for battery and the IC. Charging uses CC/CV algorithm and its fast charge current is programmable up to 400mA with an external resistor. Pre-charge and termination currents are determined relative to programmed fast charge current. The MAS6260 is available with three different floating voltage options; 4.2V, 4.35V and 4.4V.

The device has automatic power path control. When input supply voltage is available all power is taken from the input. That includes battery charging and loading from LDO and SYS pins. When valid input voltage is not available and the battery is not empty the device switches to battery power. MAS6260 includes battery overcharge, overdischarge and overtemperature protection. Additionally there is overcurrent protection at the input (VIN) and at both outputs (SYS, LDO). There are four different faulty conditions at which the device gives distinctive fault condition signals. Charging and shutdown modes are controlled from the system. In shutdown mode the battery current consumption is minimized to maximize battery life. MAS6260 is available in a small DFN-12 3.75 mm package.
