Melexis LATCH & SWITCH PORTFOLIO

Melexis Hall Latch and Switch: 20+ Years of Innovation

While inherently basic devices, Melexis' extensive latch and switch portfolio is continually growing to match and exceed the functional, flexibility, safety and power consumption needs of today's applications. Our focus on CMOS technology and TSOT packaging are just as valid today as they were 20 years ago. Countless successes have been obtained in smart appliances, consumer devices, building automation, energy, industrial, medical, transportation and automotive markets.

The hyper flexible pre-programmed latch and switch ICs are the latest additions to the extensive product family to exactly match your requirements

Why consider a pre-programmed latch or switch?

  1. These devices offer the exactly right and precise parameters for your application. No need to make compromises by choosing an approximate match: Melexis programs the exact magnetic parameters you need. Both orthogonal and planar field versions are available for every device. Minimum volumes apply.
  2. You want to minimize your total cost? Did you consider PCB-less designs, lower cost TSOT devices (lower cost of SMD versus through-hole assembly) and additional economies of scale?
  3. Your current latch or switch is end-of-life? We offer the exactly matched replacement in a small TSOT or through-hole package. No minimum volumes apply for replacements.

The right pre-programmed sensor for any application

Parameters that Melexis programs for you:

  • Bop, Brp, hysteresis
