4.5. Silicon Labs Battery Life Estimator

The Battery Life Estimator is a system design tool for battery operated devices. It allows the user to select the type

of battery they are using in the system and enter the supply current profile of their application. Using this

information, it performs a simulation and provides an estimated system operating time. The Battery Life Estimator

is shown in Figure 6.

Figure 6. Battery Life Estimator Utility

From Figure 6, the two inputs to the Battery Life Estimator are battery type and discharge profile. The utility

includes battery profiles for common battery types such as AAA, AA, A76 Button Cell, and CR2032 coin cell. The

discharge profile is application-specific and describes the supply current requirements of the system under various

supply voltages and battery configurations. The discharge profile is independent of the selected power source.

Several read-only discharge profiles for common applications are included in the pulldown menu. The user may

also create a new profile for their own applications.

To create a new profile:

1. Select the profile that most closely matches the target application or choose the "Custom Profile".

2. Click Manage.

3. Click Duplicate.

4. Click Edit.

Profiles may be edited with the easy-to-use GUI (shown in Figure 7).

C8051F96x/Si102x

10 Rev. 0.2

Figure 7. Battery Life Estimator Discharge Profile Editor

The Discharge Profile Editor allows the user to modify the profile name and description. The four text entry boxes

on the left hand side of the form allow the user to specify the amount of time the system spends in each power

mode. On the right hand side, the user may specify the supply current of the system in each power mode.

Since supply current is typically dependent on supply voltage, the discharge profile editor provides two columns for

supply current. The V2 and V1 voltages at the top of the two columns specify the voltages at which the current

measurements were taken. The Battery Life Estimator creates a linear approximation based on the input data and

is able to feed the simulation engine with an approximate supply current demand for every input voltage.

The minimum system operating voltage input field allows the system operating time to stop increasing when the

simulated battery voltage drops below a certain threshold. This is primarily to allow operating time estimates for

systems that cannot operate down to 1.8 V, which is the voltage of two fully drained single-cell batteries placed in

series.
