Product Overview
AD7280A is a lithium ion battery monitoring system qualified for automotive applications. It contains all the functions required for general-purpose monitoring of stacked lithium ion batteries as used in hybrid electric vehicles, battery backup applications and power tools. The part has multiplexed cell voltage and auxiliary ADC measurement channels for up to six cells of battery management. The AD7280A includes on-chip registers that allow a sequence of channel measurements to be programmed to suit the application requirements. The AD7280A also includes a dynamic alert function that can detect whether the cell voltages or auxiliary ADC inputs exceed an upper or lower limit defined by the user. Typical application includes lithium ion battery monitoring electric and hybrid electric vehicles power supply backup power tools.
- 12bit ADC, 1μs per ch conversion time and 6 analogue input ch, common-mode range of 0.5V to 27.5V
- 6 auxiliary ADC inputs, ±1.6mV cell voltage accuracy, on-chip voltage regulator
- Cell balancing interface and daisy-chain interface
- Internal reference of ±3ppm/°C and 1.8μA power-down current
- VDD operating range from 8V to 30V, qualified for automotive application
- High input impedance and serial interface with alert function
- 1 SPI interface for up to 48 channels, CRC protection on read and write commands
- On-chip registers for channel sequencing
- 48 lead LQFP package
- Operating temperature range from -40°C to 105°C
