Description

L9780 is an IC designed to interface a variety of wide range air fuel sensors.The device manages the oxygen pump of the wide range air fuel sensor by means of a voltage controlled current source (VCCS). The reference for the VCCS is generated by a PI controller with external compensation network in...
