Features

AFE monitoring features

– Pure digital interface

– Internal ADC measures cell voltage, die temperature, and external thermistor

– A separate, internal ADC measures pack current (coulomb counter)

– Directly supports up to three thermistors (103AT)

Hardware protection features

– Overcurrent in Discharge (OCD)

– Short Circuit in Discharge (SCD)

– Overvoltage (OV)

– Undervoltage (UV)

Additional features

– Integrated cell balancing FETs

– Charge, discharge low-side NCH FET drivers

– Alert interrupt to host microcontroller

– 2.5-V or 3.3-V output voltage regulator

– No EEPROM programming necessary

– High supply voltage absolute maximum (up to 108 V)

– Simple I2C compatible interface (CRC option)

– Random cell connection tolerant
