深圳市七悅科技有限公司，專(zhuān)注磁控霍爾元件的研發(fā)和銷(xiāo)售。
深圳七悅科技為你優(yōu)選海量完整的七悅霍爾開(kāi)關(guān)MA7022，支持在線實(shí)時(shí)詢價(jià)。
MA7022屬于高耐壓高溫雙極鎖存霍爾開(kāi)關(guān)，適用于流量計(jì)計(jì)數(shù)，無(wú)刷電機(jī)換相，筋膜槍?zhuān)绷黠L(fēng)扇電機(jī)換相。
MA7022 is an integrated Hall-Effect latch sensor with pull-up resistor 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)
