United States Patent 9
Abstract
Amicrocontroller for use in battery charging and monitoring applications is disclosed. The microcontroller includes a microprocessor and various front-end analog circuitry such as a slope A/D converter and a multiplexer for allowing a plurality of analog input signals to be converted to corre- sponding digital counts indicative of signal level. In order to make the measurements of the selected analog inputs more precise, the microcontroller uses a unique calibration pro- cedure whereby selected parameters associated with the analog circuitry that are subject to variation are measured during test and corresponding calibration constants are cal- culated therefrom and stored in program memory. These stored calibration constants are subsequently used by the microprocessor in conjunction with the digital counts of the analog input signals for calculating a more precise measure- ment of the analog input signals.
