利用可充电电池技术提供更多功率

电源

你购买了一个新设备，拆开了花哨的包装，然后看到许多人害怕的短语：不包括电池。
在任何小工具中使用一次性电池技术 - 从电视遥控器或相机 - 都可能导致任何人恶化。
没有人喜欢任何设备都没电了。
然而，对于依赖于诸如助听器之类的医疗设备的用户来说，由于这种类型的设备的功率损耗实际上是危险的，所以赌注要高得多。
直到今天，大多数助听器都使用一次性电池。
助听器电池的使用寿命可根据使用的辅助电池和电池类型而有很大差异，但可低至4天。
这迫使用户非常勤奋地确保他们总能获得备用。
对于那些有严重听力损失的人来说，这一点更为重要。
如果用户无法正常听到，更换之间的任何延迟都会令人感到不舒服甚至是危险的。
丢弃的频率也不是非常环保。
虽然它们可以回收利用，但每年有超过数百万的助听器电池进入垃圾填埋场。
对用户来说更直接的后果是，一次性电池会对通常昂贵的设备造成物理损坏。
更换电池需要打开和关闭一个非常小而脆弱的电池门，并且要求具有良好的灵活性。
由于许多助听器用户年龄较大，这对他们来说可能具有挑战性。
反复打开和关闭电池仓门会导致它最终破裂。
更糟糕的是，也可能发生氧气暴露的腐蚀，导致设备间歇性故障。
HPM10
HPM10是一种高性能电源管理集成电路（PMIC），可将可充电电池技术用于助听器和人工耳蜗。
它支持和管理许多不同的电池化学成分，包括锂离子（Li-Ion）和银锌（AgZn）。
它还能够检测镍 - 金属氢化物（Ni-Mh）和一次性锌 - 空气（锌 - 空气）电池，并相应地进行操作。
使用自动检测系统，HPM10可立即识别设备内使用的任何电池化学成分，从而提供非常通用的解决方案。
然后，它作为高效调节器运行，以提供助听器所需的电源电压，同时最大限度地减少任何耗散功率。
HPM10旨在提供支持多种电池类型或尺寸所需的灵活性。
其充电参数可以相应更新并存储在IC的非易失性存储器中。
由于深度睡眠电流消耗率仅为15 nA，HPM10还有助于通过密封的可充电电池最大限度地延长助听器的保质期。
在HPM10中设计的助听器制造商现在可以制造完全密封的辅助设备，随着时间的推移，电池门可能不会断裂，并且由于潮湿或汗水不会有任何腐蚀，因此可以更可靠地执行。

You purchase a new device, unwrap the fancy packaging, and then, see the phrase dreaded by many: Batteries not included.
The use of disposable battery technology in any gadget- from your television remote or your camera- can cause anyone aggravation. No one enjoys running out of power in any device. However for users dependent on medical devices like hearing aids the stakes are much higher as power loss of this type of equipment can actually be dangerous.
To this day, most hearing aids operate off disposable batteries. The lifespan of a hearing aid battery can greatly vary depending on what type aid and size battery is used, but can be as low as 4 days. This forces users to be extremely diligent in making sure they always have access to a spare. For those with significant hearing loss, this is even more crucial. Any delay between replacements can be uncomfortable or even dangerous if users are not able to hear properly. The frequency of discarding is also not very eco-friendly. Though they can be recycled, over millions of hearing aid batteries end up in landfills each year. Of more direct consequence to the user, disposable batteries can cause physical damage to the often-expensive device. Replacing batteries requires opening and closing a very small and frail battery door and commands good dexterity to do so. Since many hearing aid users are older, this can be challenging for them. Repeatedly opening and closing the battery compartment door can cause it to eventually break. Worse yet, corrosion from oxygen exposure can also occur, leading to intermittent failures of the device.

HPM10
HPM10 is a high-performance Power Management Integrated Circuit (PMIC) which enables rechargeable battery technology to be used in hearing aids and cochlear implants. It supports and manages a number of different battery chemistries, including Lithium Ion (Li-Ion) and Silver-Zinc (AgZn). It is also able to detect Nickel-Metal Hydride (Ni-Mh) and disposable Zinc-Air (Zn-Air) batteries and operates with those accordingly.
Using an automatic detection system, HPM10 immediately recognizes whatever battery chemistry is used within the device which provides for a very versatile solution. It then operates as a high-efficiency regulator to provide the supply voltage required by the hearing aid while minimizing the amount of any dissipated power. HPM10 is designed to provide the flexibility needed to support multiple battery types or sizes. Its charging parameters can be updated accordingly and stored in the ICs’ non volatile memory. With a Deep Sleep current consumption rate of only 15 nA, HPM10 also helps to maximize the shelf life of a hearing aid with a sealed, rechargeable battery. Hearing aid manufacturers who design in HPM10 can now make completely sealed aids, which will perform more reliably over time given battery doors may not break and there won’t be any corrosion inside due to humidity or sweat.
