General Description The Melexis MLX92223 is based on the Melexis Hall-effect switch latest platform, designed in mixed signal submicron CMOS technology. The device integrates a voltage regulator, Hall sensor, current sink-configured output driver and integrated capacitor all in a single package. The MLX92223 magnetic core is using an advanced offset cancellation system. In addition a pre- programmable temperature coefficient is implemented to compensate the natural behavior of certain types of magnets becoming weaker at high temperature. The included voltage regulator operates from 3.8 to 16V, hence covering a wide range of applications. With the built-in reverse voltage protection, a series diode on the supply line is not required so that even remote sensors can be specified for low voltage operation down to 3.8V while being reverse voltage tolerant. Advanced thermal management with current limit above V = 16.8V is implemented. The on-chip DD thermal protection switches the supply current below I if the junction temperature increases above PROT the protection threshold T . It will automatically recover once the temperature decreases below T . PROT REL The MLX92223 is delivered in a Green and RoHS compliant Plastic Single-in-Line (TO-92 flat) for through- hole mount and with integrated capacitor for PCB-less design.
