General Purpose Motion Control ICs

Currently Viewing:

The HCTL-1101 series is a high performance, general purpose motion control IC, fabricated in Broadcom CMOS technology. It frees the host processor for other tasks by performing all the time-intensive functions of digital motion control. The programmability of all control parameters provides maximum flexibility and quick design of control systems with a minimum number of components. In addition to the HCTL-1101, the complete control system consists of a host processor to specify commands, an amplifier, and a motor with an incremental encoder (such as the Broadcom HEDS-5XXX, -6XXX, -9XXX series). No analog compensation or velocity feedback is necessary.
