Overview

Our integrated circuits and reference designs help you create cell monitor unit designs that enable highly accurate monitoring of and control over the high-voltage battery stack.

Design requirements

Cell monitor unit designs often require:

  • Resolution of voltage and temperature measurement on cell level.
  • Accurate current sense on pack level.
  • Following state-of-the-art architecture regarding system redundancy in order to allow implementation of the system on the highest safety level.
