Wearing smart watches on the wrist, smart glasses on the bridge of the nose, and wireless earphones around the ears… In recent years, the smart wear industry has developed rapidly, and these products have gradually integrated into the daily lives of the public. Intelligent wearable devices provide intelligent design and development for daily wear. As an extension of mobile phone usage habits, it is common to use wearable devices to pay, make phone calls, listen to music, and reply to messages. In recent years, with the deepening of the binding between intelligent wearable devices and sports health, there has been an indispensable trend.
The problems brought about by rapid development
It is undeniable that with the development of Internet of Things technology, the application scenarios of intelligent wearable devices in daily life are constantly expanding, bringing many conveniences to our lives. But behind its rapid development, there are also many issues that cannot be ignored, among which the most worrying thing for consumers is the high failure rate of wearable devices.
From the design of wearable devices, implementing relevant protection plans can greatly reduce the system failure rate. At the moment of startup, there is often a surge voltage that, if not suppressed, can cause damage to the equipment. In addition, issues such as unstable power grids and poor quality chargers can also affect the system reliability of the equipment. These common influencing factors can be suppressed and eliminated through the OVP protection mechanism.
Safe OVP Protection IC – TMI6402T
Tuoer Micro TMI6402T – an ultra small packaged OVP protection IC that has four unique advantages compared to common OVP protection ICs on the market:
High voltage withstand: Vin can withstand up to 38V, far higher than the industry average, and can adapt to a wider range of wearable devices;
OVP fast response: The response time of OVP is as low as 100nS, which is one order of magnitude ahead of conventional ICs. Once the input voltage is too high, it quickly shuts off to avoid damage to equipment components;
6V protection+5.7V Clamp: TMI6402T has a unique clamp design, ensuring that the circuit voltage through the chip is limited to 5.7V, playing a key protective role in the subsequent circuit;
Output self-discharge: in case of power failure, it can output self discharge motor system to avoid system fault caused by MCU judgment error;
Four major advantages, recruiting hard core, while integrating static electricity protection, soft start, high load and other characteristics, can be said to be a sense of security! At the same time, it adopts a DFN1.6 * 1.6 ultra small package, saving PCB layout space, and every intelligent wearable device deserves the protection of TMI6402T.
