United States Patent 115
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. The micro- controller also includes an I°C interface for supporting a bi-directional two wire bus and data tran: ion protocol that is useful for serially communicating with other periph- eral or microcontroller devices. By making use of the I°C interface, the microcontroller can be programmed while in the end application circuit. Such a feature allows customers to manufacture boards with unprogrammed devices and then program the microcontroller just before shipping the prod- uct. This allows the most recent firmware or a custom firmware to be programmed.
