SNAS678B May 2018 – May 2019 HDC2080
PRODUCTION DATA.
In a battery-powered HVAC system thermostat, one of the key parameters in the selection of components is the power consumption. The HDC2080, with 550 nA of current consumption (the average consumption over 1s for RH and Temperature measurements), in conjunction with a MSP430, represents one way an engineer can obtain low power consumption and extend battery life. A system block diagram of a battery-powered thermostat is shown in Figure 16.
