Description
The AD7280A is a lithium ion battery monitoring system that provides accurate cell voltage and auxiliary ADC measurements for up to six cells. It features a 12-bit ADC with a conversion time of 1 μs per channel, an internal ±3 ppm/°C reference, and a cell balancing interface. The AD7280A operates from a single Voo supply ranging from 8 V to 30 V and has a power-down current of 1.8 μA. It is available in a 48-lead LQFP package and is qualified for automotive applications.
Features
12-bit ADC, 1 μs per channel conversion time
6 analog input channels, common-mode range 0.5 V to 27.5 V
6 auxiliary ADC inputs
±1.6 mV cell voltage accuracy
On-chip voltage regulator
Cell balancing interface
Daisy-chain interface
Internal reference: ±3 ppm/°C
1.8 μA power-down current
High input impedance
Applications
Lithium ion battery monitoring
Electric and hybrid electric vehicles
Power supply backup
