FN9012
features of this controller IC include programmable VID codes from the microprocessor that range from 1.050V to 1.825V with an accuracy of ±0.8%. Pull up currents on these VID pins eliminates the need for external pull up resistors. Another feature of this controller IC is the PWRGD monitor circuit which is held low until the CORE voltage increases, to within 18% of the programmed voltage. Over-voltage, 24% above programmed CORE voltage, results in the PWRGD output going low to indicate that the CORE is above the specified limit. Under voltage is also detected and results in PWRGD going low if the CORE voltage falls 18% below the programmed level. Over-current protection folds back the output voltage to 95m V, reducing the regulator dissipation. These features provide monitoring and protection for the microprocessor and power system.
