Integrated circuit for processing signal of programmable Hall sensor for vehicle safety system, has adjusting circuit connected with output of comparator for adjusting output logic voltage based on comparator output signal at output

摘要

The circuit has an adjustable voltage supply (140) including an input (149), which is connected with a connection pin (120). A comparator (147) is connected with the input for comparison of an output logic voltage (OVdd) or a comparison voltage (Vrefio), which is proportional to the output logic voltage, with an input logic voltage or a voltage (Vmeas), which is proportional to the input logic voltage. An adjusting circuit (14) is connected with an output (147a) of the comparator for adjusting the output logic voltage based on a comparator output signal (Vok) at the output of the comparator.
