Automotive Hall-sensor output driver for wide-range loading-conditions

The output driver includes a D/A converter, an output buffer, open-circuit detection circuits and bi-directional data transfer circuits. The main challenges in this development were accuracy and settling requirements in combination with the wide range of capacitive loading and leakage at high temperatures.
