NJU7346
Single-phase DC Brushless Motor Driver IC
■ GENERALDESCRIPTION
■ PACKAGE OUTLINE
The NJU7346 is a single-phase DC brushless motor driver IC
designed for small and high power fan-motor applications.
It provides a low operating current of 3mA (typ.) and low
saturation output voltage at high output current operation, which
offers a high efficiency motor driving. It has a FG (frequency
generator) output useful for various control systems and thermal
NJU7346R
shutdown circuit useful for high-current applications. Further it
( MSOP10 (VSP10) )
incorporates feed-back resistances to provide optimized output
wave for low noise motor driving.
The NJU7346 is available in a small and thin surface mount
package of MSOP10 (TVSP10), which provides downsizing and
thinning in motor applications.
