Industrial Automation PMIC Capacity Tightens, onsemi Lead Times Elongate
Industrial automation manufacturers are reportedly facing extended lead times for Power Management ICs (PMICs), particularly from key suppliers like onsemi. This tightening capacity is primarily impacting specialized PMICs designed for motor control, process automation, and robotics applications.
The global electronic components market is observing a notable tightening in the supply of Power Management ICs (PMICs) specifically tailored for industrial automation applications. Reports from several procurement channels indicate that lead times for these components have begun to lengthen significantly, with some forecasts extending into early Q1 2027. This trend is particularly pronounced for devices used in high-precision motor drives, programmable logic controllers (PLCs), and advanced robotics.
Leading suppliers such as onsemi, a significant player in the industrial PMIC segment, are at the forefront of this capacity constraint. While specific wafer fabrication facility (fab) utilization rates remain proprietary, industry analysts suggest that a combination of sustained demand from the industrial sector and the specialized nature of these PMICs—which often require mature but dedicated process technologies—are contributing to the current bottleneck. Unlike consumer electronics, industrial applications demand greater robustness, wider operating temperature ranges, and longer product lifecycles, necessitating distinct manufacturing lines and qualification processes.
The impact is being felt across the industrial automation value chain. Manufacturers of factory equipment are preemptively raising inventory levels where possible, but smaller and mid-sized enterprises are finding it challenging to secure allocations for critical PMICs. This situation could potentially delay the deployment of new automation projects and impact the refurbishment cycles of existing industrial infrastructure. Procurement engineers are advised to engage in proactive long-term forecasting with their key suppliers and explore secondary sources for qualified alternatives.
The current capacity limitations are not directly attributable to a single catastrophic event but rather to an ongoing, subtle divergence between increasing demand for industrial digitalization and the slower-paced expansion of specialized manufacturing capacities for these robust components. As global industrial production continues its push towards greater automation and efficiency, the demand for resilient PMICs is projected to remain strong, urging suppliers to re-evaluate their long-term capacity investment strategies for this critical segment.
