China Screwless Terminal Blocks Factory
Similarly, the maximum value of the UVLO parameter must be lower than the maximum rated voltage of the first component in the system. By designing an over-voltage protection (OVP) device in front of the device, the surge effect and the host's insufficiency can be eliminated. Although NCP360 consumes extremely low current, it has extremely fast turn-off time. This function is integrated in the more advanced model NCP361.
The Vbus voltage value is clearly defined by the USB specification: the rated voltage is 5V, up to 5. This maximum ringing ripple voltage depends on the input capacitance and parasitic inductance of the mobile device.5μs turn-off time makes this device a first-class device on the market today, as shown in Figure 5. The RθJA chart is provided in the device data sheet, or you can contact an ON Semiconductor sales representative for further information.
Platform manufacturers will integrate USB connectors in their designs.0 and 2. Figure 1: Charging the built-in battery through an external device. Usually the Vbus pin is connected to the power input pin of the transceiver (sometimes through a low-dropout voltage regulator with a maximum rated voltage of 6V).
.Nowadays, China Screwless Terminal Blocks Factory devices have USB connectors, which realize data exchange and/or charge the battery of portable devices through USB. Benchmark tests on some AC-DC power supplies show poor line regulation performance, and even worse in the presence of optocoupler feedback (switching charger) losses, the output voltage may rise to 20V. When designing the OVP part, the heat dissipation problem should not be ignored due to the internal MOSFET driving the critical current.
