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 preprogrammable 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 VDD = 16.8V is implemented. The on-chip thermal protection switches the supply current below IPROT if the junction temperature increases above the protection threshold TPROT. It will automatically recover once the temperature decreases below TREL. The MLX92223 is delivered in a Green and RoHS compliant Plastic Single-in-Line (TO-92 flat) for throughhole mount and with integrated capacitor for PCB-less design. # 3901092223 Rev.001 Page 2 of 11 Datasheet September/2018 MLX92223LUA-AAA 2-Wire Hall Effect Latch with Resistive Output Characteristic Contents 1.
