Description
General part information
L9780 Series
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 order to adapt the device to different sensors. The user can choose between two different networks using the SPI interface. L9780 is fully compatible with most sensors on the market.
The internal timing state machine automatically manages all the operations needed for a right sequencing of the measurement process. All the main time values can be configured by SPI.
