深圳市七悅科技有限公司，專業(yè)從事磁控霍爾開關(guān)的研發(fā)和銷售。
GENERAL DESCRIPTION
MA7013 is an 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)..
