Melexis announced the availability of a complete sense and drive IC solution for automotive brushed DC motor applications such as window lift, sun roof and seat adjustment. Faced with shorter time to market challenges and the need to incorporate more smart features, the solution aids engineers to quickly develop a high performance, low bill-of-material DC motor drive and sense design with a dedicated application-optimized chipset.
 
The two-IC combination, consisting of two new products, the MLX81325 motor pre-driver and the new MLX92255 Hall-effect latch, provides a cost-effective approach to designing a distributed motor drive control application using an automotive industry interface communication standard.
 
Providing the sense function and interfacing to the MLX81325 in this combined solution is the MLX92255, a dual Hall-effect latch that has two-speed outputs. Using a mixed-signal CMOS process technology, the device integrates two Hall sensors that feature advanced offset cancellation and two open-drain output drivers.
 
“OEM customers are constantly looking for new ways to design-in more smart functionality into their distributed network automotive solutions,” Marc Lambrechts, product manager for Embedded Motor Drivers at Melexis, said.
