MLX92242

 

 

The MLX92242 is a new generation hall effect switch designed in mixed signal submicron CMOS technology with offers end of line calibration. The device integrates a voltage regulator, hall sensor with advanced offset cancellation system and a current sink-configured output driver, all in a single package.
Based on a brand new platform, the magnetic core is using an improved offset cancellation system allowing faster and more accurate processing while being temperature insensitive and stress independent. In addition a programmable temperature coefficient is implemented to compensate the natural behaviour of certain types of magnest becoming weaker with rise in temperature.
The included voltage regulator operates from 2.7V to 24V, hence covering a wide range of applications.
With the built-in reverse voltage protection, a serial resistor or diode on the supply line is not required, so that even remote sensors can be specified for low voltage operation down to 2.7V while being reverse voltage tolerant.
In an event of a drop below the minimum supply voltage during operation, the under voltage lock-out protection will automatically freeze the device, preventing the electrical perturbation to affect the jmatnetic measurement circuitry. The output current state is therefore only updated based on a proper and accurate magnetic measurement result.
The two-wire interface not only saves one wire, but also allows implementation of diagnostic functions as reverse polarity connection and malfunction detection.
The on-chip thermal protection also switches off th output if the junction temperature increases above an abnormally high threshold. It will automatically recover once the temperature decreases below a safe value.
