8904 3-PHASE BRUSHLESS DC MOTOR CONTROLLER/DRIVER

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.

8904 Features

* and modes of operation, such as the speed control parameters, startup current limit, sleep mode, direction, and diagnostic modes. The A8904 is fabricated in Allegro’s BCD (Bipolar CMOS DMOS) process, an advanced mixed-signal technology that combines bipolar, analog and digital CMOS, and DMOS power d
