NJU7367
Single-phase DC Brushless Motor Driver IC
„ GENERAL DESCRIPTION
„ PACKAGE OUTLINE
The NJU7367 is a single-phase motor driver IC.
It features lock detect, FG output and thermal
shutdown circuit functions.
The motor rotational speed is controlled by PWM
input pulse.
The NJU7367 is available in a small and thin
8-lead MSOP(TVSP) package.
