GENERAL DESCRIPTION
The NJM2625 is a 3-phase DC brush-less motor
control IC with PWM control.
It incorporates hall amplifiers, PWM control circuits,
totem-pole pre drivers for external power MOS
transistors, current limit and frequency generator
circuit.
The NJM2625 easily implements speed control and
rotation direction control for DC motor application.
