The DA2010 provides a limit switch implementation circuit for PWM applications. Selectable polarities and enables provide a very versatile and flexible protection scheme. Motor phase is also reversible, as is a reference/index switch input for use with controllers such as the LM629 that require a positive edge for activation. The DA2010 is available in a variety of packages, including DIP20, PLCC20, SOIC20 and others on special order.
