  • Shared switching for multiple loads
    Publication number: 20070262811
    Abstract: Circuits, methods, and systems are directed to controlling the amount and polarity of current to multiple loads with switches, where the loads share switching components. The loads may be thermoelectric elements, which heat or cool based on the state of the switches. The switches may be run in a single mode during a duty cycle, or multiple successive modes during the duty cycle to achieve full control of the loads.
