1 Functional Diagram

The included voltage regulator operates from 2.7 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.

Protection

In the 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 magnetic

measurement circuitry. The output state is therefore only

updated based on a proper and accurate magnetic

measurement result.

2 General Description

automatic output shut-off is activated in case of a

prolonged short-circuit condition. A self-check is then

periodically performed to switch back to normal

operation if the short-circuit condition is released.

The on-chip thermal protection also switches off the

output if the junction temperature increases above an

abnormally high threshold. It will automatically recover

once the temperature decreases below a safe value.

The Melexis MLX92211 is the second generation Hall-

effect latch designed in mixed signal CMOS technology.

The device integrates a voltage regulator, Hall sensor with

advanced offset cancellation system and an open-drain

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 is implemented a

negative temperature coefficient to compensate the

natural behaviour of magnets becoming weaker with rise

in temperature.

With latching magnetic characteristics, the output is

turned low or high respectively with a sufficiently strong

South or North pole facing the package top side. When

removing the magnetic field, the device keeps its previous

state.
