3. Electrical Characteristics
All voltages are referenced to ground (GND). Positive currents flow into the IC. The absolute maximum
ratings given in the table below are limiting values that do not lead to a permanent damage of the device but
exceeding any of these limits may do so. Long term exposure to limiting values may affect the reliability of
the device. Reliable operation of the MLX81205/07/10/15 is only specified within the limits shown in
Operating conditions.

[1] Target temperature specification after qualification. With temperature applications at TA>125°C a reduction of chip internal power
dissipation with external supply transistor is mandatory. The extended temperature range is only allowed for a limited period of time,
customer’s mission profile has to be agreed by Melexis as a mandatory part of the Part Submission Warrant.
