深圳七悦科技为你优选海量完整的霍尔开关MA7022B，支持惠州在线实时询价。
MA7022B属于高耐压高温双极锁存霍尔开关，适用于流量计计数，无刷电机换相，筋膜枪，直流风扇电机换相。
MA7022B 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)
