Safe, reliable systems

High-accuracy battery monitoring, current sensing and isolation, and integrated diagnostics all contribute to increased system reliability.

Engineering efficient energy storage systems

Accurate monitoring

Battery monitoring integrated circuits (ICs) measure cell voltages, temperature and pack current; perform cell balancing; and monitor and protect cells. Accurate monitoring enables more efficient battery use, resulting in longer run times and a reduction in battery size and cost. Our pack monitors accurately measure voltage and temperature to diagnose and manage the safety of battery packs.

Our battery cell monitoring ICs work well in Controller Area Network (CAN) or daisy chain-based architectures to meet your requirements.
