LIN-Slave for relay and DC motor control
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 MLX81150 is only specified within the limits shown in “Operating
conditions”.

The IC can have 6 different hardware modes. The exact functionality of these modes depends on the
hardware and software configuration:
• Reset:
o triggered by hardware. When VS or VDDA or VDDD drop below a critical level, the complete
chip is powered down.
o The analogue and digital supply regulators are disabled. No functionality is available in this
mode.
• Normal mode. Main application running
o Microcontroller fully functional
o Analogue fully functional
• Power Saving Mode
o Application CPU halted
o Wake-up by interrupt possible
• Under voltage: triggered by the hardware under voltage detection interrupt. (VS_UV)
o Microcontroller fully functional.
o Analogue functionality under software control.
o Reduced current capability on VDDA below VS=5.5V.
• Over voltage: triggered by the hardware over voltage detection interrupt. (VS_OV)
o Microcontroller fully functional
o Analogue functionality powered down by hardware or software.
• Sleep Mode: Triggered by the software.
o Microcontroller powered down
o Digital and analogue supply powered down.
o Sleep Mode and wake-up functionality running on help supply Vaux
[1] Development target, IC will work down to 3.9V with reduced analogue characteristics, Digital part still works, Memories will keep
their content. Some analogue parameter will drift out of limits, but chip function can be guaranteed.
Before going down to 3.9V the VS has to be at the startup of the IC for a certain time > 6V to guarantee a correct reset!
Evaluation will only be done on sample basis in the preproduction phase; no production test; no life time test
[2] With temperature applications at TA>105°C a reduction of chip internal power dissipation with an external transistor in the
voltage regulator path is obligatory. The extended temperature range is only allowed for a limited period of time, customer’s
mission profile has to be agreed by Melexis as an obligatory part of the Part Submission Warrant (PSW). Some analogue
parameter may drift out of limits, but chip function can be guaranteed.
