NJU7367A
Single-phase DC Brushless Motor Driver IC
GENERAL DESCRIPTION
PACKAGE OUTLINE
The NJU7367A is a single-phase motor driver IC.
It features lock detect, FG output, thermal shutdown
circuit and start up assist functions.
The motor rotational speed is controlled by PWM
input pulse.
The NJU7367A is available in a small and thin
8-lead MSOP(TVSP) package.
