A Smart Solution for Smart Meter Power-Path Management

Figure 1. Circuit schematic

Some smart meter applications require an external wireless communication module to be attached to them. The power requirements imposed are that the module should limit its supply current to be within a 100 – 150mA range. There is also a requirement for a super capacitor (supercap) backup supply to continue
