PWM TYPE 3-PHASE DC BRUSHLESS MOTOR CONTOROL IC

¨ GENERAL DESCRIPTION

¨ PACKAGE OUTLINE

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.
