AD7280AWBSTZ-RL Description

Short technical summary and product information.

The AD7280AWBSTZ-RL from Analog Devices is a comprehensive Lithium Ion Battery Monitoring System IC. It offers a 12-bit ADC with a conversion time of 1 µs per channel, supporting up to 6 analog input channels and 6 auxiliary ADC inputs. The device provides a common-mode range of 0.5 V to 27.5 V and boasts a cell voltage accuracy of ±1.6 mV.

 

Designed for versatility, the AD7280AWBSTZ-RL includes an on-chip voltage regulator, cell balancing interface, and daisy-chain interface capabilities. It operates from a VDD range of 8 V to 30 V and has an operating temperature range of -40°C to 105°C. The integrated SPI interface allows for communication and control, with CRC protection for data integrity.

 

This IC is qualified for automotive applications and is suitable for monitoring stacked lithium ion batteries in electric and hybrid electric vehicles, power supply backups, and power tools. It is supplied in a 48-lead LQFP package suitable for surface mounting.

 

The device features an internal reference with a stability of ±3 ppm/°C and a low power-down current of 1.8 µA. Its high input impedance and fault protection for over/under voltage make it a robust solution for battery management systems.
