Maxim Integrated Products introduces the MAX9921 dual, 2-wire Hall-effect sensor interface IC. This single-chip solution supplies and monitors the current drawn by two Hall-effect sensors, filters the sensed-current level, and outputs the corresponding logic level. The MAX9921 reduces interconnect cost by allowing the Hall-effect sensor to be grounded locally, which eliminates the need for an additional wire. To further reduce solution cost and save space, it replaces multiple discrete components and enhances performance with features such as input diagnostics and fault protection. |
