Introduction to BQ20Z90DBTR-V110

The BQ20Z90DBTR-V110 is a single-cell Li-Ion battery monitor from Texas Instruments. This module is a highly integrated, easy to use and cost effective solution for managing and monitoring single cells in consumer and industrial applications. BQ20Z90DBTR-V110 monitors and reports the state of charge and health of the battery as well as additional features for safety and time-intensive operations.

Application Field and Working Principle

BQ20Z90DBTR-V110 is ideally suited for consumer and industrial applications that require monitoring of single-cell Li-Ion batteries. This product family integrates charge and discharge current and voltage regulation, over-temperature and under-voltage protection, self-diagnostics and advanced protection features. Additionally, BQ20Z90DBTR-V110 can accurately estimate the remaining capacity of the battery and provide a linear relationship between state-of-charge and remaining capacity.The BQ20Z90DBTR-V110 monitors and adjusts the current and voltage supplied to the battery by managing its charging and discharging cycles. It accurately calculates the remaining capacity of the battery and provides an output signal (SOC) that is proportional to the battery’s remaining capacity. This data is then used to inform the user about the current status of the battery. The module can be programmed to provide additional features such as low-power enabled charging, automatic charge/discharge balancing, under-voltage and over-temperature protection, and self-diagnostics.

Conclusion

In conclusion, BQ20Z90DBTR-V110 is an ideal choice for monitoring single-cell Li-Ion batteries in consumer and industrial applications. It provides a reliable, easy to use, and cost effective solution that can accurately monitor the state of charge and health of the battery. Additionally, it is also equipped with advanced features such as low-power enabled charging, automatic charge/discharge balancing, under-voltage and over-temperature protection, and self-diagnostics for additional safety and time-intensive operations.
