This Custom Integrated Circuit was a “Charge Locked” differential capacitance sensor based on charge redistribution principles design for use in High Reliability Automotive ABS Brake applications. The device was specified to operate over a temperature range of -40c to 150c with Military level device qualification standards and an emphasis on analog element long term stability. Key IP Elements;
Self Timed Switch Capacitor Signal Processing
Field Programmable Polysilicon fuses
On-Chip Fuse Blowing Control Electronics
14 Bit Digital to Analog Converters
Automotive Over-voltage and Reverse Polarity Protection
IC Design Services was engaged to consult on design, manufacturability and field reliability. Over a fifteen yield period IC Design Services re-tooled this design in three difference technology nodes and consulted with the customer to maintain multiple manufacturing sources.
