... X NOTE: 4. Applies only to the ICL3241 and ICL3243. 11 The ICL3221, ICL3223, and ICL3243 utilize a two pin approach where the FORCEON and FORCEOFF inputs determine the IC’s mode. For always enabled operation, FORCEON and FORCEOFF are both strapped high. To switch between active and powerdown modes, under logic or software control, only the FORCEOFF input need be driven. The FORCEON state isn’ ...
