东莞现货供应 MA7023 扫地机器人电机PCBA 专用 双极锁存霍尔开关 霍尔元件 霍尔传感器

MA7023 is an integrated Hall-Effect latch sensor with pull-up resistor designed for electronic

commutation of brush-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).
