Abstract
A position sensor and variable reluctance type controller interface circuit ( ) is provided. The circuit ( ) includes a position sensor ( ) having an output terminal (OUT) and generating a position signal. A variable reluctance type controller ( ), having an input bus ( ), is electrically coupled to the position sensor ( ) via a voltage divider circuit ( ). The circuit ( ) supplies a voltage differential output signal in response to the position signal to the input bus ( ). A method of interfacing between the position sensor ( ) and the controller ( ) is also provided. The method includes generating a position signal. The reference voltage on the controller ( ) is divided to an approximately fixed voltage level. The approximately fixed voltage level is supplied to a negative input terminal (INPUT−) on the variable reluctance type controller. The position signal is received on a positive input terminal (INPUT+) of the controller ( ).
