MA7003 广东东莞大量供应 LED灯 手电筒 专用 全极微功耗霍尔开关 霍尔元件

MA7003AA/P3属于全极微功耗霍尔开关，输出OD（需要加上拉电阻）。

GENERAL DESCRIPTIONMA7003 is a three-terminal Hall Effect sensor device with an output driver. The device is using CMOS process includes an on-chip Hall voltage generator for magnetic sensing, a comparator that amplifies the Hall voltage, and a Schmitt trigger to provide switching hysteresis for noise rejection, and open-drain output, and an internal temperature compensated circuits. This method reduces the offset voltage normally caused by device over molding and thermalstress.The output is switch with either north or South Pole of sufficient strength will turn the outputon (low). The output will be turned off (high) under no magnetic field. While the magnetic fluxdensity (B) is larger than operate point (Bop), the output will be turned on (low); the output islatched until B is lower than release point (Brp) and then turned off (high).

 

FEATURES- 1.65V to 5.5V battery operation- Chopper Stabilized Technology- Operation with North or South Pole- High sensitivity and high stability of the magnetic switching points- Low Profile SOT23-3L &TSOT23-3L Package
