General Description
The SS109 is a unipolar Hall effect sensor IC fabricated
from mixed signal CMOS technology. The device
integrates a voltage regulator, Hall sensor with dynamic
offset cancellation system, Schmitt trigger and an
open-drain output driver, all in a single package.
It incorporates advanced chopper stabilization techniques to provide accurate and stable magnetic switch points. There
are many applications for this HED – Hall Electronic Device - in addition to those listed above.
Thanks to its wide operating voltage range and extended choice of temperature range, it is quite suitable for use in
automotive, industrial and consumer applications.
The device is delivered in a Small Outline Transistor (SOT) or in a Plastic Single In Line ( SIP 3L flat). Both 3-lead
packages are RoHS compliant.

家里的灯局好些个都是灯具市场的熟人那里买的,陆陆续续的就坏掉很多。 普通的螺口还好,家乐福买些个飞利浦的节能灯,然后网上偶尔买几个LED灯就换上去了。顶上的圆的面灯(自家叫法,不专业)一年多的寿命,基本都翘了 还有个灯灭就灭了,十天半月的突然就会亮着,真是见鬼。 买来的质量不行,就自己改造个。下面是做好的LED灯板其中LED驱动电源在右侧,不知道哪家的,也没测试直接就用上了。 PCB是普通板,不是...
