Frequently Asked Questions
What is the BQ20Z40PWR-R1 and what does it do?
The BQ20Z40PWR-R1 is a multi-cell Li-Ion battery fuel gauge and protection IC from Texas Instruments. It monitors voltage, current, and temperature via an integrated 16-bit ADC, reports State-of-Charge and State-of-Health over SMBus, and provides protection against overcharge, overdischarge, and overcurrent conditions in 2-4 series cell battery packs.
How many battery cells does the BQ20Z40PWR-R1 support?
The BQ20Z40PWR-R1 supports 2 to 4 series-connected Li-Ion or Li-Polymer cells. It includes built-in cell balancing to maintain uniform charge levels across all cells, which extends overall battery pack life and improves safety during charging and discharging cycles.
What communication interface does the BQ20Z40PWR-R1 use?
The BQ20Z40PWR-R1 uses the SMBus (System Management Bus) interface, which is compatible with I2C at 100 kHz. This allows the host system to query real-time battery parameters such as remaining capacity, voltage, current, temperature, cycle count, and battery health status.
What package does the BQ20Z40PWR-R1 come in, and where can I buy it?
The BQ20Z40PWR-R1 is available in a TSSOP-24 power package (PWR suffix). It is priced from $7.36 and available in stock at FindMyChip with worldwide shipping. You can submit a quote request directly on the product page for volume pricing or expedited sourcing.
