  Application Note 160
  July 2016
  Single-Channel Power Supply Monitor with Remote
  Temperature Sense
  Nathan Enger
  Introduction
  Many applications with a single power regulator can benefit
  from the monitoring and control features of a power supply manager, but most power supply manager ICs have
  more than one channel. In an application that only has one
  power supply, there will be an unused set of DAC and ADC
  pins. Instead of letting the unused channel go to waste, we
  can use these pins, and a bit of microcontroller code, to
  sense remote temperature. The LTCВ®2970 is a 2-channel
  power supply monitor and controller. Each channel has
  two 14-bit ADCs to measure voltage and current, and
  one 8-bit DAC to servo the power supply voltage. It can
  drive an attached bipolar junction transistor to make a
  delta-VBE measurement, and the microcontroller can use
  the measured voltages to calculate temperature. The cost
  of the added components is as little as 3 or 4 pennies.
