3.6. 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 3.
Figure 3. Battery Life Estimator Utility
From Figure 3, 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 4).
