US72 Datasheet (Melexis) - (US72 / US73) Single Coil Fan Driver

US72, (US72 / US73) Single Coil Fan Driver

The US72 and US73 provide a monolithic solution for driving single-coil fans.

The bridge drivers provide bi-directional current through the single phase motor winding.

US72: The tachometer/Frequency Generator (FG) version produces a logic signal, which is aligned with the Hall plate signal.

US73: Th
