七悅科技，專注霍爾，您身邊的霍爾芯片供應商！
深圳市七悅科技有限公司，從事磁控霍爾開關(guān)的研發(fā)和銷售。
深圳七悅科技為你優(yōu)選海量完整的玩具霍爾開關(guān)，電子玩具霍爾芯片MA7002，支持揭陽在線實時詢價。

??MA7002是高速測速霍爾，全時測試，CMOS輸出，全極感應，適合應用在電子跳繩，卷發(fā)器測速等。GENERAL DESCRIPTION
? ? ? ? MA7002 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 push-pull output, and an internal temperature compensated circuits.
This method reduces the offset voltage normally caused by device over molding and thermal
stress.
? ? ? ? The output is switch with either north or South Pole of sufficient strength will turn the output?on (low). The output will be turned off (high) under no magnetic field. While the magnetic flux?density (B) is larger than operate point (Bop), the output will be turned on (low); the output is?latched 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 and SIP-3L(TO-92S) Packages
