Description for the BQ25570

The bq25570 device is specifically designed to efficiently extract microwatts (µW) tomilliwatts (mW) of power generated from a variety of high output impedance DC sources likephotovoltaic (solar) or thermal electric generators (TEG) without collapsing those sources. Thebattery management features ensure that a rechargeable battery is not overcharged by this extractedpower, with voltage boosted, or depleted beyond safe limits by a system load. In addition to thehighly efficient boosting charger, the bq25570 integrates a highly efficient, nano- power buckconverter for providing a second power rail to systems such as wireless sensor networks (WSN) whichhave stringent power and operational demands. All the capabilities of bq25570 are packed into asmall foot-print 20-lead 3.5-mm x 3.5-mm QFN package (RGR).

Carrier options

You can choose different carrier options based on the quantity of parts, including full reel, custom reel, cut tape, tube or tray.

custom reel is a continuous length of cut tape from one reel to maintain lot- and date-code traceability, built to the exact quantity requested. Following industry standards, a brass shim connects an 18-inch leader and trailer on both sides of the cut tape for direct feeding into automated assembly machines. TI includes a reeling fee for custom reel orders.

Cut tape is a length of tape cut from a reel. TI may fulfill orders using multiple strips of cut tapes or boxes to satisfy the quantity requested.

TI often ships  tube or tray  devices inside a box or in the tube or tray, depending on inventory availability. We pack all tapes, tubes or sample boxes according to internal electrostatic discharge and moisture-sensitivity-level protection requirements.
