Wayon - WP1681: Temperature protection IC for USB connection

WP1681 uses an external NTC thermal sensor to control the status of the built-in NMOS switch, protecting the device from overheating. The IC uses an additional charge pump circuit to control the NMOS switch, ensuring that the VBUS power is disconnected when the temperature exceeds the allowed threshold and restored when the temperature returns to normal.  

The product is designed to operate stably in harsh conditions, helping to protect charging devices from overheating. With an operating voltage of 4.5V to 5.5V, current consumption of 0.5 mA, suitable for many different charging devices and helps save energy and increase operating efficiency. WP1681 is a suitable product for USB or Type-C charging device applications.
