AH5771
General Description
AH5771 is the integrated Hall sensor with output drivers designed
for electrical commutation of brush-less DC motor application.
The device is as follows: one-chip Hall voltage generator for
magnetic sensing; the error amplifier that amplifies the Hall
voltage; a comparator is to provide switching hysteresis for noise
rejection; the full bridge driver for sinking and driving current load.
Internal band gap regulator is used to provide temperature
compensated bias for internal circuits and allows a wide
operating supply voltage range. The device includes features
such as Rotor Lock Protection with rotor lock detection and
automatic self-restart to avoid damage to the coil when the rotor
is blocked. AH5771 is rated for operation over-temperature range
from -40℃ to 100℃ and voltage range from 2.5V to 15V. The
device is available in low profile package SIP-4L.
