| abstract | A hybrid monolithic IC (10) that is standardized for controlling various types of electrical equipment, such as circuit breakers, motor controllers and the like. The IC is a hybrid monolithic IC, fabricated in CMOS technology. The IC includes an on-board microprocessor (30), an A/D subsystem (64) and various input/output devices which make it adaptable for use in various types of electrical equipment. In order to improve the resolution of the A/D subsystem, circuitry is provided, which includes current and voltage ranging amplifiers (Fig. 53) for ranging analog input voltage and current signals and compensating internal offsets, in such amplifiers, inherent in CMOS linear circuits which can affect the accuracy of the least significant bit. Novel auto-zero circuitry (Figs. 36, 39, 40 and 41) is provided for controlling the offsets in the ranging amplifiers. An electrical overcurrent circuit (FIG. 86) provides both digital based modeling (FIG. 85A) and analog based modeling (FIG. 85A) of the temperature of an electrical conductor to simulate the conductor temperature during all expected operating conditions including a condition when electrical power is unavailable to the electrical overcurrent circuitry. |
