Allegro MicroSystems
Download the A8902CLBA datasheet PDF.
This datasheet also covers the A8902 variant, as both devices belong to the same 3-phase brushless dc motor controller/driver family and are provided as variant models within a single manufacturer datasheet.
Key Features
and modes of operation, such as the speed control parameters, startup current limit, sleep mode, diagnostic modes, and others. The A8902CLBA 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 devices. The A8902CLBA is provided in a 24-lead wide-body SOIC batwing package. It provides for the smallest possible construction in surface-mount.
