Description

The reference design describes a power management solution for data concentrators and smart meters that require both super capacitor and battery as backup power. The designed circuit implements uninterrupted power supply to drive GPRS module and other system loads by switching among the power grid, the super capacitor and the battery in setting sequence. The reference design also includes a simple, cost-effective linear charger circuit for the super capacitor and the battery.

Features
  • Capability to drive the GPRS Module
  • Both super capacitor and battery for backup power
  • Power sequence implementation for the power grid and backup power
  • Super capacitor 1-V to 2.65-V operational voltage
  • Linear charger circuits for the super capacitor and battery
