Hall-effect latch is PCB-less
The MLX92223 integrates the additional passive components normally needed to interface Hall-effect latches to ECUs for the accurate motorised seat position detection. This level of integration removes the need for the sensor to be mounted on a PCB, which in turn enables smaller solutions, allowing OEMs to integrate latches and modules even where space is restricted, to further increase customer comfort and safety.
The magnetic core used by Melexis features advanced offset cancellation with a programmable temperature coefficient, allowing the MLX92223 to compensate for magnets that may exhibit variation over temperature. The MLX92223 also includes a voltage regulator and current sink configured output. Other features include reverse supply voltage protection with advanced thermal management to limit the current if the junction temperature exceeds the protection threshold. The MLX92223 is available in a TO-92-3L package and operates over an extended temperature range of -40°C to +150°C.
