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).
