NJU7366
Single-phase DC Brushless Motor Driver IC
„ GENERAL DESCRIPTION
„ PACKAGE OUTLINE
The NJU7366 is a single-phase motor driver IC.
It features thermal shutdown circuit and start up assist
functions.
The motor rotational speed is controlled by DC input
voltage.
The NJU7366 is available in a small and thin 8-lead
MSOP(TVSP) package.
