In addition to that an ID has been integrated on the IC

to have a complete traceability throughout the

process flow.

Lockout

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.

Amplifier

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

The open drain output is fully protected against short-

circuit with a built-in current limit. An additional

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 MLX92231 is a Hall-effect unipolar

switch designed in mixed signal CMOS technology.

The device integrates a voltage regulator, Hall sensor

with advanced offset cancellation system, automotive

qualified EEPROM and an open-drain output driver,

all in a single package.

Based on the existing robust 922xx platform, the

magnetic core has been equipped with a non-volatile

memory that is used to accurately trim the switching

thresholds and define the needed output magnetic

characteristics (TC, Bop, Brp, Output pole

functionality).
