NJM2626
PWM TYPE 3-PHASE DC BRUSHLESS MOTOR CONTROL IC
s GENERAL DESCRIPTION
s PACKAGE OUTLINE
The NJM2626 is a 3-phase DC brush less motor control
pre-driver IC with PWM control.
It takes hall IC inputs and generates motor driving
waveform.
Output pre-driver is optimized to work with external power
MOS transistors for better power handling.
The NJM2626 can easily implement 3-phase DC motor
application with speed control feature.

Motor
• A rotation direction change must be made after motor stopped completely.
• When PWM duty is extremely small, two or more switching elements can not be driven entirely.
In such case, switching elements will generate excess heat and it may cause destruction of the
switching devices. Therefore, extensive heat evaluation is necessary for switching device selection
particularly in consideration of the area of safety operation (ASO).
