CSH277A4 Overview
The CSH277A4 is an integrated Hall sensors with output drivers designed for electronic mutation of brushless DC motor applications. The device includes an on-chip Hall voltage generator for magnetic sensing, a parator that amplifies the Hall voltage, and a Schmitt trigger to provide switching hysteresis for noise rejection, and plementary open collector drivers for sinking large current loads. An internal bandgap...
