NJU7347
Single-phase DC Brushless Motor Driver IC
s GENERAL DESCRIPTION
s PACKAGE OUTLINE
The NJU7347 is single-phase DC brushless motor driver IC.
It features MOS-FET driver circuit for better output
characteristics.
It features Lock Detect, Frequency Generator Output and
Thermal Shutdown Circuit.
Maximum output current is 200mA(12V). Input offset voltage
is ±7mV.
It is suitable for 12V high current small fan-motor applications.
