ATA6870 - Li-Ion Battery Management

Description

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.

Features

  • 12-bit Battery-cell Voltage Measurement Simultaneous Battery Cells Measurement in Parallel Cell Temperature Measurement Charge Balancing Capability.
  • Parallel Balancing of Cells Possible Integrated Power Supply for MCU Undervoltage Detection Less than 10 µA Standby Current Low Cell Imbalance Current (< 10 µA) Hot Plug-in Capable Interrupt Timer for Cycling MCU.
