MA7015風扇熱管理的無刷直流風扇（BLDC）規(guī)格書PDF中文資料

GENERAL DESCRIPTION

MA7015 is a Hall effect sensor IC. The device 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-drain 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).
