深圳市七悅科技有限公司，主營霍爾元件，電機霍爾，全極霍爾，單極霍爾，線性霍爾。

MA7012 is an unipolar Hall effect sensor IC. The device 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. An internal

band-gap regulator is used to provide temperature compensated supply voltage for internal

circuits and allows a wide operating supply range.

If a magnetic flux density larger than threshold Bop, OUT is turned on(low). The output state is held until a magnetic flux density reversal falls below Brp causing OUT to be turned off (high)..
