Product Description
Product Overview
The GH1187 is an integrated Hall Effect latched sensor designed for electronic commutation of brush-less DC motor applications. It features an on-chip Hall voltage generator, comparator, Schmitt trigger for noise rejection, and an open-collector output. The device operates over a wide supply voltage range with temperature compensation and provides protection against reverse power connection. It is suitable for applications requiring precise rotor position sensing, current switching, and speed measurement in brush-less DC motors and fans.
