• Manufacturer Part Number: MLX90277EGOSR0-0
• Description: Dual Programmable Linear Hall Effect Sensor
• Manufacturer: MELEXIS [Melexis Microelectronic Systems]

The output buffer can be configured to accommodate capacitive loads and improve the saturation voltage
(output swing). The two bit parameter, MODE, sets the current capacity of the output amplifier. Melexis sets
this parameter to 1 at final test. This parameter is not used by the end customer.
The Memory Lock feature prevents the device from entering programming mode and from any changes to the
EEPROM. The entire EEPROM is locked by setting the MEMLOCK parameter to 1. This should be the last
parameter set in the application.
A unique ID number is programmed into the EEPROM of every IC. The ID number gives Melexis additional
traceability to better service its customers. The ID number is composed of the lot number, wafer number and
wafer coordinates (X and Y). Memory is also available for the customer to add a serial number of the product
or any other data.
