Breakout board based on the Texas Instruments BQ76920 integrated circuit designed for charging and discharging 3-cell lithium battery packs. The board can be managed by any programmable processor (for example Arduino with the provided libraries). Thanks to a special library, it is possible to measure and communicate, via I2C bus, the amount of charge (Coluomb) transferred to the battery. The board is equipped with a 10k NTC type temperature sensor which allows to detect if the battery temperature exceeds the critical one, in order to avoid the degradation of the LiPo cells and, in the most extreme cases, the burst. The board is also equipped with a connector for the balanced recharge that the integrated BQ76920 is able to manage.

N.B.  the breakout board is supplied already assebled and tested.

• Gestione: tramite I2C-Bus

The breakout boards are prototyping boards containing the already welded needed component, whose connections are carried outside the bases on easily usable connections for pitch and termination; generally the connections are pitches with a pitch of 2.54 mm, like those of the classic integrated DIP. To help those who would like to use SMD components but doesn’t have the means or the qualities to weld it, a number of integrated sensors (including sensors, switching power supplies, battery chargers, linear amplifiers, etc.) have been identified and mounted on ready-to-use bases. These breakout boards are both an aid for those who want to have ready in a traditional format the best of SMD electronics, both for those who can work with SMD components - need to have these components available on prototyping boards to apply them to circuits existing and testing, that is, to create prototypes that integrate the functions of the relative integrated, before realizing the final printed circuit of a device.
