LTC2945: 12-Bit Wide Range Power Monitor
@verbatim
The LTC2945 is a rail-to-rail system monitor that measures current, voltage, and
power. It features an operating range of 2.7V to 80V and includes a shunt
regulator for supplies above 80V to allow flexibility in the selection of input
supply. The current measurement range of 0V to 80V is independent of the input
supply. An onboard 0.75% accurate 12-bit ADC measures load current, input
voltage and an auxiliary external voltage. A 24-bit power value is generated by
digitally multiplying the measured 12-bit load current and input voltage data.
Minimum and maximum values are stored and an overrange alert with programmable
thresholds minimizes the need for software polling. Data is reported via a
standard I2C interface. Shutdown mode reduces power consumption to 20uA.
