The LTC®2970 is a dual power supply monitor and margining controller with an SMBus patible I2C bus interface.

A low-drift, on-chip reference and 14-bit ΔΣ 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.
