AN1188: EFP01 Coulomb Counting
This application note describes the configuration, calibration, and operation of the Coulomb counter on the EFP01 Energy Friendly Power Management IC (PMIC). The integrated Coulomb counter can losslessly measure the charge drawn from each DCDC andLDO. A software example demonstrating the Coulomb counting feature is included in this application note.
The EFP01 Energy Friendly PMIC product family is designed to support a range of battery-powered applications, as well as other systems requiring high performance and low energy consumption.
A block diagram of the EFP01 family is shown in Figure 2.1 EFP01 Block Diagram on page 3. The diagram shows a superset of features available on the family, which vary by part number. For more information about specific device features, consult the Ordering Information section in the datasheet.
KEY POINTS:
• Ability to losslessly measure charge drawn from each DCDC and LDO.
• Internally integrated calibration registers for accurate calibration.
• Example C-code
• Multiple IDE projects
