The BQ769x0 family of robust analog front-end (AFE) devices serves as part of a complete pack monitoring and protection solution for next-generation, high-power systems, such as light electric vehicles, power tools, and uninterruptible power supplies. The BQ769x0 is designed with low power in mind: Subblocks within the IC may be enabled or disabled to contr.
• 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)
– Secondary protector fault detection
• 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 r.
