NJU7360
Single-phase DC Brushless Motor Driver IC
GENERALDESCRIPTION
PACKAGE OUTLINE
The NJU7360 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 2mA (typ.) and low
saturation output voltage at high output current operation,
which offers a high efficiency motor driving. It also has a high
output current capability of 1000mA (peak) and 400mA
(continuous). The NJU7360 has a hall bias circuit and hall
NJU7360RB1
( MSOP8 (TVSP8 ))
signal amplifier for output wave optimization, which offers a low
noise motor driving. It also has useful functions such as a FG
(frequency generator) output for speed detection and thermal
shutdown. The NJU7360 is available in a small and thin
package of MSOP8 (TVSP8), which provides downsizing and
thinning in motor applications.
