Product Description

The BQ25504RGTT is an integrated ultralow-power Boost Converter with battery management for energy harvester specifically designed to efficiently acquire and manage the microwatts (µW) to milliwatts (mW) of power generated from a variety of DC sources like photovoltaic (solar) or thermal electric generators. The BQ25504 is the first device of its kind to implement a highly efficient boost converter/charger targeted toward products and systems, such as wireless sensor networks (WSNs) which have stringent power and operational demands. The design of the boost converter starts with a DC-DC boost converter/charger that requires only microwatts of power to begin operating. Once started, the boost converter/charger can effectively extract power from low-voltage output harvesters such as thermoelectric generators (TEGs) or single- or dual-cell solar panels. The boost converter can be started with VIN as low as 330mV and once started, can continue to harvest energy down to VIN=80mV.
Ultra low-power with high-efficiency DC-DC boost converter/charger
<330nA Ultra-low quiescent current
Programmable dynamic maximum power point tracking (MPPT)
Integrated dynamic maximum power point tracking for optimal energy extraction
Input voltage regulation prevents collapsing input source
User programmable under-voltage and overvoltage levels
On-chip temperature sensor with programmable over-temperature shutoff
Battery good output pin
Programmable threshold and hysteresis
Warn attached microcontrollers of pending loss of power
Green product and no Sb/Br
This device has limited built-in ESD protection, leads should be shorted together or the device placed in conductive foam during storage or handling to prevent electrostatic damage to the MOS gates.
