The TPB76016 is a multicell battery stack monitor that measures up to 17 series battery cells with a total measurement error of less than 5mV typical. The cell measurement range is from 0V to 5V, with supporting Li-ion, Li-Polymer, and LiFePO4 battery types. All 17 cells can be measured within 20ms. The TPB76016 also
integrates an ADC to measure charge/discharge current and provides a coulomb counter.
The TPB76016 integrates a safety engine that provides reliablity protection for OV, UV, OTC, UTC, OTD, UTD,COC, DOC, SCD, SOV with programmable detection
threshold and delay time. The COC, DOC and SCD use a hardware comparator for fast protection.
The TPB76016 provides internal cell balance, the max cell balance current is 40mA, for higher cell balance current,an external cell balance circuit may be used.
The device has a host communication peripheral supporting 1Mbps SPI. TPB76016 is available in 48-pinLQFP package, and operation temperature ragne is from
-40℃ to 85℃.
