com LX1801 "SPARK" for MED427A-1 CARLSBAD DIVISION TARGET DATASHEET DESCRIPTION KEY FEATURES Low peak current consumption: <2mA 3V operation 2 Small form factor: 1.
45mm Double/single output voltage option Solder bumped die The MSC-LX1801 is the IC1 "Spark" for the MED427A-1 module.
The "Spark" chip has an oscillator, a voltage doubler, and a level shifter.
The oscillator is a "555" timer variant where the external resistor (Rref) determines the frequency.
The voltage doubler increases the output (OUT) of the oscillator by a factor of 2 (times VDDLO).
The voltage doubler also provides a single output voltage if disabled (EN2x).
This level shifter shifts voltage inputs from the lower voltage (VDDlo) to the higher voltage (VDDhi).
