LTC2970HUFD-1#PBF (LINEAR TECHNOLOGY)

The LTC2970HUFD-1#PBF from Linear Technology is a dual I2C power supply monitor and margining controller in 24 pin QFN package. It is a dual power supply monitor and margining controller with an SMBus compatible I2C bus interface. A low drift, on-chip reference and 14bit ?? A/D converter allow precise measurements of supply voltages, load currents or internal die temperature. Fault management allows ALERT to be asserted for configurable overvoltage and undervoltage fault conditions. Two voltage buffered, 8bit IDACs allow highly accurate programming of DC to DC converter output voltages. The IDACs can be configured to automatically servo the power supplies to the desired voltages using ADC. The bus address is set to 1 of 9 possible combinations by pin strapping the ASEL0 and ASEL1 pins. It is used in dual power supply voltage servo, monitoring supply voltage and current, programmable power supplies and programmable reference.
