ATA6870 Datasheet Li-Ion Battery Management

Manufacturer: Atmel (now Microchip Technology)

General Description

www.DataSheet4U.com The ATA6870 is a measurement and monitoring circuit designed for Li-ion and NiMH multicell battery stacks in hybrid electrical vehicles.

The ATA6870 monitors the battery-cell voltage and the battery-cell temperature with a 12-bit ADC.

The circuit also provides charge-balancing capability for each battery-cell.
