Product Type: Battery Management
BQ25505RGRT General Description
The bq25505 device is specifically designed to efficiently extract the microwatts (µW) to miliwatts (mW) of power generated from a variety of DC energy harvesting, high-impedance sources like photovoltaic (solar) or thermal electric generators (TEGs) without collapsing those sources. The battery-management features of the bq25505 ensure that a secondary rechargeable battery is not overcharged by this extracted power, with voltage boosted, nor depleted beyond safe limits by a system load. The integrated multiplexer gate drivers autonomously switch the system load to a primary nonrechargeable battery if the secondary battery voltage falls below the user-defined VBAT_OK threshold.
Features
- Ultra Low-Power With High-Efficiency DC-DC Boost Charger
- Cold-Start Voltage: VIN ≥ 600 mV
- Continuous Energy Harvesting From Input Sources as Low as 100 mV
- Ultra-Low Quiescent Current of 325 nA
- Input Voltage Regulation Prevents Collapsing High-Impedance Input Sources
- Ship Mode With < 5 nA From Battery
- Energy Storage
- Energy can be Stored to Rechargeable Li-Ion Batteries, Thin-Film Batteries, Super-Capacitors, or Conventional Capacitors
- Battery Charging and Protection
- Internally Set Undervoltage Level
- User-Programmable Overvoltage Level
- 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
- Programmable Maximum Power Point Tracking (MPPT)
- Integrated MPPT for Optimal Energy Extraction From a Variety of Energy Harvesters
- Gate Drivers for Primary (Nonrechargeable) and Secondary (Rechargeable) Storage Element Multiplexing
- Autonomous Switching Based on VBAT_OK
- Break-Before-Make Prevents System Rail Droop
