Capstan Motor

[Morpheus4893]

Does anyone know how to wire up a capstan motor from a VCR? The chip number is: LB11883N, & seems to drive the drum head motor as well, but I cannot find a datasheet for this chip... The motor has 12 pins, but the chip must be an on board driver...  ???

Hi Morpheus,
                    the ic u r looking for is most probably made by sanyo japan. u can check for it on the sanyo website, u can find a description for it but i doubt that u'll find the datasheet. it happens that certain components that are for OEM use donot have the datasheets available for general use. the component may be customised for the OEM company. i may be wrong, but its been the case with me, i needed the datasheet for a 3 phase motor driver used in a panasonic FDD and a power amp in a sony music system, all i could find was a description but no datasheet. try ur luck maybe u can get it on the sanyo website

Tried their site, not a chance of getting a datasheet for that particular chip, just an older one with a different package, i think the only way to find the pinout would be to probe the voltages on all 12 pins in a working VCR with the same motor & chip...
