The previous article Wholesale DIN 41612 Connectors provides more detailed information, and also provides the OVLO and UVLO parameter values compatible with the wall adapter power supply. Figure 4: The soft-start process of the OVP device that overcomes the surge Even if the Vusb or wall adapter rapid output rise (hot plug) occurs, no voltage spike is observed at the Vout end of the device, thanks to the 4ms soft-start control. In order to save power,

the USB will enter a suspend mode when there is no data traffic. OVP devices are needed to overcome this problem. In order to provide a higher level of protection, overcurrent protection (OCP) features can be added to these devices.675V, which can effectively protect the downstream system to withstand a voltage of 6V, and the Vusb ripple voltage can reach 5. The typical value of 700ns/maximum value of 1.

The OVLO level must be higher than the maximum operating output voltage of Vbus (5.25V. This special sequence runs through the gradual ascent of the PFet gate, see Figure 4. A 1μF ceramic capacitor is enough to solve this problem. How to design the USB current capability is 100mA in normal mode (unconfigured mode), but up to 500mA in configured mode. Electrical characteristics and protective measures

Downstream systems connected via USB can be powered by multiple types of hosts. When the Vbus power supply is used to charge the lithium-ion battery (in most cases, the maximum rated voltage is The voltage is 7V or 10V) can also be connected to the input pin of the charger. Figure 5: NCP360 has a very fast turn-off time. When connecting a standard USB source device such as a personal computer (PC),
