ATS177 is an integrated Hall effect latched sensor designed for electronic commutation of brush-less DC motor applications. 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-collector output.
The Anachip ATS477 is an integrated circuit that combines a Hall sensor with bi-directional output drivers. It is specifically designed for the electrical commutation of single-coil brush-less DC motors and fans. The device features an on-chip Hall voltage generator, error amplifier, comparator, and frequency generator (FG) to provide rotation speed signals.
