Abstract
A watch dog circuit for a computer system includes a data transform chip, a counter, a clock generator, a first power supply, and a second power supply. The data transform chip is connected to a System Management Bus (SMBUS) for transforming the data that received from the SMBUS. The counter counts the data received from the data transform chip, and outputs a reset signal to a South Bridge when the count is completed. The clock generator is connected to the counter. The first power supply is connected to the data transform chip and the counter. The second power supply is connected to the clock generator. The watch dog circuit monitors the output data of the SMBUS and outputs a reset signal to reset the computer system when the computer system is down.
