Overview
8904 A8904SLB (SOIC) 3-PHASE BRUSHLESS DC MOTOR CONTROLLER/DRIVER WITH BACK-EMF SENSING The A8904SLB and A8904SLP are three-phase brushless dc motor controller/drivers designed for applications where accurate control of highspeed motors is required.
The three half-bridge outputs are low on-resistance n-channel DMOS devices capable of driving up to 1.
2 A.
The A8904 provides complete, reliable, self-contained back-EMF sensing, motor startup and running algorithms.
A programmable digital frequency-locked loop speed control circuit together with the linear current control circuitry provides precise motor speed regulation.
A serial port allows the user to program various features and modes of op...
