  3. TI Portfolio of MSP430 related products

  4. Focus for Cal Poly MSP430 Projects • Low power applications • Low power and green power supply options • Energy harvesting • Types of transducer input devices • Device selection signal conditioning solutions • Output devices • Some tools to make the task a bit easier

  5. MSP430 Compatible • A few choices for MSP- 430 Low power applications • Lowest Power, highest efficiency • Reverse battery protection • Enable/disable function • Output should be disconected when disabled • Lowest power supply voltage • Buck-boost topology • Voltage inverter for ± power supplies
