Tiny, Micropower Hall-Effect Switches From Diodes Incorporated Deliver Compatibility With Low-Voltage Chipsets
Diodes Incorporated (Diodes) (Nasdaq: DIOD) introduces three new Hall-effect switches, the AH1899A/B/S, which operate from a low supply voltage and at extremely low quiescent current to extend battery lifetime in mobile and portable devices. The AH1899A/B/S are used to detect the open/closed status of covers and cases for portable electronic devices, such as smartphones and tablets. They are also designed for proximity detection in digital cameras and handheld gaming consoles, as well as general contactless switching.
Diodes 公司（Diodes）（纳斯达克股票代码：DIOD）推出三款新的霍尔效应开关， AH1899A/B/S，它们在低电源电压和极低的静态电流下运行，以延长移动和便携式设备的电池寿命。AH1899A/B/S 用于检测便携式电子设备（例如智能手机和平板电脑）的机盖和外壳的打开/关闭状态。它们还设计用于数码相机和手持游戏机中的近距离检测，以及一般的非接触式开关。
These switches, with their supply-voltage range of 1.1V to 2.0V, seamlessly integrate with state-of-the-art application chipsets operating at 1.2V, ensuring ease of use. The power-efficient architecture of these parts lowers the typical average operating current to as little as 0.95μA at 1.2V. The hibernating clocking system in these switches help maximize system energy savings to extend the runtime of battery-operated devices.
这些开关的电源电压范围为 1.1V 至 2.0V，可与在 1.2V 下运行的最先进应用芯片组无缝集成，确保了易用性。这些器件的节能架构将 1.2V 时的典型平均工作电流降低至低至 0.95μA。这些开关中的休眠时钟系统有助于最大限度地节省系统能源，从而延长电池供电设备的运行时间。
The omnipolar AH1899A/B/S operate with either north or south magnetic poles close to the package surface. Leveraging an advanced chopper-stabilized topology, the operating (BOP) and release (BRP) points display minimal drift with supply voltage and temperature. Two sensitivity grades are available, giving designers flexibility to tailor the switch response for their application. The AH1899B and AH1899S operate when the magnetic field strength (B) exceeds 30 Gauss and release at below 20 Gauss. The AH1899A is a high-sensitivity version that operates at 18 Gauss and releases at 12 Gauss. All versions remain off when no field strength is present.
全极 AH1899A/B/S 在靠近封装表面的北磁极或南磁极时运行。利用先进的稳定斩波器拓扑结构，操作 (BOP) 和发布 (BRP) 点显示与电源电压和温度的偏差最小。有两种灵敏度等级可供选择，使设计人员可以灵活地为其应用定制开关响应。AH1899B 和 AH1899S 在磁场强度 (B) 超过 30 高斯时运行，并在低于 20 高斯时释放。AH1899A 是一款高灵敏度版本，在 18 高斯下运行，在 12 高斯下释放。当没有场强时，所有版本都保持关闭状态。
Designers can also take advantage of board-space savings by selecting these switches, which are packaged as X2-DFN1010-4 (Type B) surface-mount devices. At just 1.0mm x 1.0mm, and 0.4mm high, the footprint is smaller than typical alternatives. In addition, the internal circuitry integrates pull-up and pull-down resistors to save the PCB area usually needed for external components.
设计人员还可以通过选择这些封装为 X2-DFN1010-4（B 型）表面贴装器件的开关来充分利用节省电路板空间的优势。尺寸仅为 1.0 毫米 x 1.0 毫米，高 0.4 毫米，占地面积小于典型替代品。此外，内部电路集成了上拉和下拉电阻，以节省外部组件通常所需的PCB面积。
The AH1899A, AH1899B, and AH1899S are in production and available from $0.11 in 5,000 piece quantities. These, and the full portfolio of Hall-effect sensors are included in the Hall-effect sensor part selector.
