L9966 Datasheet FlexInput IC for automotive applications Product status link L9966 Product summary Order code L9966CB-TR Package TQFP48 Packing Tape and reel Features AEC-Q100 qualified 12 V and 24 V systems compatible (operating battery supply voltage 5.5 V-36 V) Programmable interface with 15 total inputs: – 12 for connection to external analog loads (with connection to VVAR, VDD5 and clamped battery VPRE, with resistance measurement) ◦ 4 with also λ sensor functionality ◦ 4 with also SENT functionality – 3 for connection to external digital switches (with connection to VPRE) Programmable pull-up/down current sources Integrated precise resistance measurements 12-bit ADC for voltage measurements 15-bit ADC for resistance measurements Variable reluctance sensor / Hall sensor Interface 1 analog output channel + 4 digital output channels SPI interface for device configuration and data communication Overtemperature protection Thermal resistance Rth(j-c) = 3 K/W Description The L9966 is an automotive grade IC designed to be used as sensors interface. Up to 15 channels are available for analog sensing, resistance measurement and digital sensing (e.g. temperature, lambda, pressure, position sensors). The L9966 allows replacing a number of discrete components and it gives the possibility to change the sensors across different applications without modifying the PCB hardware. Target applications are Engine Control Units and Body/Chassis Modules. DS124...
