DC2561A

DC2561A demonstration circuit features the LTC®2992, a rail-to-rail system monitor that measures current, voltage, and power of two supplies. It features an operating range of 2.7 to 100V and includes a shunt regulator for supplies above 100V. The voltage measurement range of 0V to 100V is independent of the input supply. Two ADCs simultaneously measure each supply’s current. A third ADC monitors the input voltages and four auxiliary external voltages. Each supply’s current and power is added for total system consumption. Minimum and maximum values are stored and an over range alert with programmable thresholds minimizes the need for software polling. Data is reported via a standard l2C interface. Shutdown mode reduces power consumption to 25µA typically. The demo board features nested pads for a range of sense resistor package sizes to support a wide range of power applications. It is populated for a 5A application.
