Other industrial battery pack (1S-9S)

Block diagram

Overview

Our integrated circuits and reference designs help you create highly reliable 1S-9S industrial battery packs with protection, monitoring, cell balancing, authentication and gauging for applications like electronic point-of-sale (EPOS) battery packs, Bluetooth® speaker battery packs and surveillance camera battery packs.

Design requirements:

Innovative industrial battery pack (1S-9S) designs often require:

  • Robust voltage, temperature, current and short-circuit protection.
  • Accurate current and voltage sensing and individual cell monitoring to ensure safety.
  • Accurate indication of real-time battery capacity and state-of-health.
  • Low standby current and ultra-low shipment power consumption.
