Typical Application (continued)

9.2.2 Detailed Design Procedure

When the focal constraint is the battery, the selection of a low power voltage reference, a micro-controller and

display is mandatory. The first step in the design is the calculation of the power consumption of each device in

the different mode of operations. An example is the LMP91000; the device has gas measurement mode, sleep

mode and micro-controller in low-power mode which is normal operation. The different modes offer the possibility

to select the appropriate timer interval which respect the application constraint and maximize the life of the

battery.
