BQ25570 Energy Harvester Module

Energy Harvester Module based on BQ25570 Ultra Low Power DC to DC Boost converter

The BQ25570 IC from Texas Instrument is a Nano Power Boost Charger and Buck Converter. This module is based on BQ25570 IC which is specifically designed to efficiently extract microwatts (µW) to milliwatts (mW) of power generated from a variety of high output impedance DC sources like photovoltaic (solar) or thermal electric generators (TEG) without collapsing those sources. The battery management  features ensure that a rechargeable battery is not overcharged by this extracted power, with voltage boosted, or depleted beyond safe limits by a system load. In addition to the highly efficient boosting charger, the bq25570 integrates a highly efficient, nano- power Loads buck converter for providing a second power rail to systems such as wireless sensor networks (WSN) which have stringent power and operational  demands. 

Features Of BQ25570 Energy Harvester Module

  • Cold-start Voltage: VIN ≥ 330 mV
  • Continuous Energy Harvesting From VIN as low as 100 mV 
  • Input Voltage Regulation Prevents Collapsing High Impedance Input Sources 
  • Full Operating Quiescent Current of 488 nA (typical) 
  • Ship Mode with < 5 nA From Battery
1. Energy Storage 
  • Energy can be Stored to Re-chargeable Li-ion Batteries, Thin-film Batteries, Super- 
  • capacitors, or Conventional Capacitors
2. Battery Charging and Protection 
  • Internally Set Undervoltage Level
  • User Programmable Overvoltage Levels
3. Battery Good Output Flag 
  • Programmable Threshold and Hysteresis
  • Warn Attached Microcontrollers of Pending Loss of Power
  • Can be Used to Enable or Disable System Loads
4. Programmable Step Down Regulated Output (Buck)
  • High Efficiency up to 93%
  • Supports Peak Output Current up to 110 mA (typical)
5. Programmable Maximum Power Point Tracking (MPPT)
  • Provides Optimal Energy Extraction From a Variety of Energy Harvesters including Solar Panels, Thermal and Piezo Electric Generators

Applications Of BQ25570 Energy Harvester Module

  • Energy Harvesting
  • Solar Chargers
  • Thermal Electric Generator (TEG) Harvesting
  • Wireless Sensor Networks (WSN)
  • Low Power Wireless Monitoring
  • Environmental Monitoring
  • Bridge and Structural Health Monitoring (SHM)
  • Smart Building Controls
  • Portable and Wearable Health Devices
  • Entertainment System Remote Controls
