Battery monitoring capability for 5~16 series cells; support Li-ion, Li-Polymer, and LiFePO4 battery Packs;

Reliable and flexible protection FET driver; Integrated dual-charge pump for high-side NFET driver; Integrated multi-purpose high-side PFET driver, support pre-charge, pre-discharge, and parallel charge path short protection; Support MCU control directly, by register, or by CFETOFF/DFETOFF pin;

Extensive protection suit, including cell voltage, open-wire fault, internal temperature, cell temperature, FET temperature, charging/discharging current, etc;

Support current cascade protection, high-precision ADC-based & quick-response comparator-based; Multiple fault reporting method: traditional ALERTn, or DCHG/DDSG pins; Could be compatible with external low-side NFET driver;  Highly programmable protection strategy, each fault source's protective action and ALERTn could be individually masked; Integrated charger-remove detection and load-remove detection, support autonomous fault recovery;

Two independent delta-sigma ADCs: Low temp-coefficient reference, ±2mV / ±15mV cell voltage measurement accuracy (typical / -20℃~85℃); Independent programmable decimation-ratio for each ADCs; 400us conversation time for 1-cells (typical); High accuracy current measurement ±5LSB； Multi-purpose voltage-ADC, for cell-voltage, temp-sense etc; independent programmable time-interval for each purpose-series, independent programmable decimation-ratio for each purpose-series; Support autonomous measurement and command trigger measurement; Support synchronized voltage and current measurement for individual cell impedance analysis; Human-readable ADC result, 100uV/LSB for voltage-ADC and 8uV/LSB for current ADC;

Up to eight external thermistors, and TS3 could be configured as FET temp sense;

Integrated coulomb counter

Integrated balance timer up to 1000s, support auto cell measure frequency down to get larger balance duty cycle; Integrated internal balance over-temp-protection;
