NJU7356
Single-phase DC Brushless Motor Driver IC
GENERALDESCRIPTION
PACKAGE OUTLINE
The NJU7356 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
NJU7356RB1
current capability of 1000mA (peak) and 400mA (continuous).
The NJU7356 has useful functions such as a FG (frequency
( MSOP8 (TVSP8 ))
generator) output useful for various control systems, lock detect,
auto-release (c-less type), thermal shutdown and linear driving
which offers low noise motor driving. The NJU7356 is available in a
small and thin package of MSOP8 (TVSP8), which provides
downsizing and thinning in motor applications.
