詳細(xì)描述

MAS6011 監(jiān)控包含小型太陽(yáng)能電池的電池供電系統(tǒng)的電源電壓和充電情況。該 IC 的電流消耗極低，為 110 nA，這意味著該系統(tǒng)可以在非常低的光照條件下充電，并且還可以在斷電模式下保持?jǐn)?shù)年之久，并且在充電前仍可直接使用電池供電。

為了能夠在光線(xiàn)非常有限的條件下為電池充電，通常使用大型太陽(yáng)能電池。另一方面，由于在強(qiáng)烈陽(yáng)光下過(guò)電壓，這很容易損壞電池。MAS6011 解決了這一難題，并將在大范圍的光強(qiáng)度 (lx) 內(nèi)為二次 3V 電池提供安全保護(hù)。

開(kāi)關(guān)電平設(shè)計(jì)用于 VL 型可充電鋰釩電池。與更傳統(tǒng)的電池相比，這些電池是緊湊的紐扣形二次電池，具有非常高的能量。每年的自放電率低于 2%，這使得它們?cè)诳赡軣o(wú)需充電而長(zhǎng)期儲(chǔ)存的系統(tǒng)中作為電源非常有用。

MAS6011 monitors the supply voltage and charging of a battery-powered system containing a small solar cell. The current consumption of this IC is extremely low, 110 nA, which means the system can charge from very low light conditions and also stay in power down mode for years and still operate directly from the battery before recharging.

To be able to charge a battery also in conditions with very limited light, a large solar cell is usually used. This can on the other hａnd easily destroy the battery due to over voltage during strong sun light. MAS6011 solves this dilemma and will give secure protection of a secondary 3V battery over a big range of light strengths (lx).

The switching levels have been designed for usage with VL-type rechargeable lithium vanadium batteries. Those batteries are compact, button-shaped, secondary batteries with very high energy compared to more traditional batteries. The self discharge rate is less than 2% a year which makes them very useful as a power source in systems that might be stored for a long time without re-charging.
