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). * * * * * W W W.Microsemi .COM IMPORTANT: For the most current data, consult MICROSEMI's website: http://www.microsemi.com BLOCK DIAGRAM EN2X VDDlo Ref RREF ENhi VDDhi ENlo VSS Voltage Doubler 2x OUThi Oscillator VSS VDDlo Level Shifter OUTlo Simplified Block Diagram LX1801 LX1801 TJ (C) 10 to 55 PACKAGE ORDER INFO Package Number LX1801 Copyright 2001 Rev. 0.2b, 2002-06-17 Microsemi Carlsbad Division 5973 Aveniva Encinas, Suite 101, Carlsbad 92008, Fax (760) 431-0541 1 LX1801 "SPARK" for MED427A-1 CARLSBAD DIVISION TARGET DATASHEET ABSOLUTE MAXIMUM RATINGS Input Upper Supply Voltage (VDDhi)........................................................ 0.0V to +20.0V Input Lower Supply Voltage (VDDlo) ......................................................... 0.0V to +4.0V ESD Voltage ................................................................................................................. 2kV Storage Temperature Range(TSTOR)..................................................................0C to 55C Storage humidity...............................................................................................10% to 90% PACKAGE PIN OUT W W W.Microsemi .COM 9 10 5 4 3 2 1 8 Note: Exceeding these ratings could cause damage to the device.
