The AD7280ABSTZ is a Li-ion Battery Monitoring System has multiplexed cell voltage and auxiliary ADC measurement channels for up to six cells of battery management. An internal ±3ppm/°C reference is provided that allows a cell voltage accuracy of ±1.6mV. The ADC resolution is 12bits and allows conversion of up to 48 cells within 7µs. The AD7280A operates from a single VDD supply that has a range of 8 to 30V (with an absolute maximum rating of 33V). The part provides six differential analog input channels to accommodate large common-mode signals across the full VDD range. The input pins assume a series stack of six cells. In addition, the part includes six auxiliary ADC input channels that can be used for temperature measurement or system diagnostics. The AD7280A includes on-chip registers that allow a sequence of channel measurements to be programmed to suit the application requirements.
● On-chip voltage regulator
● Cell balancing interface
● Daisy-chain interface
● High input impedance
● Serial interface with alert function
● On-chip registers for channel sequencing
