NJU7343/44/45

Single-phase DC Brushless Motor Driver IC

GENERAL DESCRIPTION

PACKAGE OUTLINE

The NJU7343/ 44/ 45 is a single-phase DC brushless

motor driver IC developed for a small fan motor. Adopting

the CMOS process, it can provide a low saturation output

voltage that is effective in high current conditions.

This driver includes Lock Detect / Auto Reset and Thermal

Shutdown Circuit for safety fan operation. Each of the

drivers has FG output (NJU7343), Half FG output

(NJU7344), and RD output (NJU7345).

It adopts small VSP10 package for downsizing and

slimming motors. It is suitable for applications for small and

high output fan motors.
