Abstract:A design scheme of multi-channel wide-range constant current source is provided.This design can not only discharge with constant current in low-voltage load,but also control the discharging mode accurately.At the same time,the full-digital control style adopted by the design scheme implements the control of multi-channel with constant current,furthermore it also realized the intelligent management about the turning on or off of the constant current source according to the requirement.The technical index shows that the current controlling can range from
Keywords:OPA549  constant-current source  multi-channel
