七悅科技，專注霍爾，您身邊的霍爾芯片專家！

深圳市七悅科技有限公司，專業(yè)從事磁控霍爾開關的研發(fā)和銷售。

深圳七悅科技為你優(yōu)選海量完整的七悅霍爾開關MA7020B，支持在線實時詢價。

MA7020B屬于高耐壓高溫雙極鎖存霍爾開關，適用于流量計計數(shù)，無刷電機換相，筋膜槍，直流風扇電機換相。

GENERAL DESCRIPTION

    MA7020B is an integrated Hall effect latched sensor designed for electronic commutation of b-less DC motor applications. The device is using HV BCD 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-collector 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).
