ADBMS1818 Datasheet 18-cell Battery Monitor

Manufacturer: Analog Devices

Overview: Data Sheet ADBMS1818 18-Cell Battery Monitor with Daisy Chain.

General Description

The ADBMS18181 is a multicell battery stack monitor that measures up to 18 series connected battery cells with a total measurement error (TME) of less than 3.0 mV.

The cell measurement range of 0 V to 5 V makes the ADBMS1818 suitable for most battery chemistries.

All 18 cells can be measured in 290 µs, and lower data acquisition rates can be selected for high noise reduction.

Key Features

  • Measures up to 18 battery cells in series.
  • 3 mV maximum total measurement error.
  • Stackable architecture for high voltage systems.
  • Built-in isoSPI interface.
  • 1 Mb isolated serial communications.
  • Uses a single twisted pair, up to 100 meters.
  • Low EMI susceptibility and emissions.
  • Bidirectional for broken wire protection.
  • 290 µs to measure all cells in a system.
  • Synchronized voltage and current measurement.
  • 16-bit Δ-Σ ADC with programmable thir.
