七悅科技，專注霍爾，您身邊的霍爾開關(guān)專家！

深圳市七悅科技有限公司，專注磁控霍爾元件的研發(fā)和銷售。

深圳七悅科技為你優(yōu)選海量完整的MA7021，支持在線實時詢價。

MA7021 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).
