STMicroelectronics TDA7272A

The TDA7272A novel applied solution is based time for motors with a low number of poles. The on a tachometer control system without using realized circuit is extended by a second feed forsuch extra tachometer system. The information of ward loop in order to improve such system by a the actual motor speed is extracted from the mofast auxiliary control path.

DESCRIPTION

TDA7272A are high performance motor speed controller for small power DC motors as used in cassette players. BLOCK DIAGRAM Powerdip(16+2+2) ORDERING NUMBER: TDA7272A Using the motor as a digital tachogenerator itself the performance of true tacho controlled systems is reached. A dual loop control circuit provides long term stability and fast settling behaviour. This is advanced information on a new product now in development or undergoing evaluation. Details are subject to change without notice. June 1992 1/16 TDA7272A
