【New Product Launch】 Safer AI Wearables! Awinic’s New OVP+OCP Protection Chip Delivers Comprehensive Safeguarding

2026-03-31

By 2026, AI wearables have evolved from trendy gadgets to an everyday essential, ushering in a new phase of large-scale adoption. Looking back at 2025, smart ring shipments surpassed 4 million units, with brands like Oura, Samsung, and Ringcon making strategic moves. AI-powered smartwatches, leveraging core capabilities such as health monitoring and motion analysis, continue to expand in the global market at a compound annual growth rate of 12%. However, as functionality and usage scenarios broaden, reliability and safety concerns have emerged as critical pain points across the industry. In response, Awinic Electronics has launched a dedicated OVP+OCP protection chip, establishing a robust safety barrier to ensure the stable, round-the-clock operation of AI wearables.

Product Advantages

Superior Port Voltage Tolerance + Fast Input Overvoltage Protection + Output Clamping:
Leveraging advanced BCD process technology, the chip delivers up to 32V port voltage tolerance, combined with <1µs fast overvoltage protection and 5.8V output clamping. This triple-layer protection effectively safeguards against overvoltage, surges, and other abnormal events.

Low Impedance Ensures Charging Reliability

Compared with competitors, it offers lower on-resistance. Particularly for pogo pin + contact applications, when contact issues or oxidation lead to increased impedance, it works with the DPM function of the new charging management IC to ensure reliable charging. For Type-C interfaces, it also reduces IR loss in the charging path, improving efficiency and minimizing heat generation — a critical factor for wearable devices.

Reliable and Safe Overcurrent Protection

The charging ports of micro devices such as smart rings and watches are highly integrated. Using non-original chargers or experiencing poor contact can easily lead to short circuits, directly damaging the motherboard chips. Awinic Electronics' new OVP+OCP product features an optimized circuit design. When a transient overcurrent event occurs, it first attempts to shut down and then restart to ensure operational reliability. However, if overcurrent occurs more than four consecutive times, it will directly cut off power to ensure circuit safety.

Miniaturized Package Solves System Design Challenges

Through differentiated package design, Awinic Electronics not only offers the traditional cost-effective DFN2*2 package (AW35018DNR) but also introduces an ultra-compact FCDFN1*1-4L package (AWP35021FDR) for applications such as xWS earbuds and smart rings. Despite its small size, it delivers a continuous overcurrent capability of 1.5A.
