8.1 Application Information

The TPS25200 is a 5-V eFuse with precision current limit and over-voltage clamp. When a target device such as a mobile data-card device is hot plugged into a USB port as shown in Figure 8-1, an input transient voltage could damage the target device due to the cable inductance. Placing the TPS25200 at the input of mobile device as overvoltage and overcurrent protector can safeguard these target devices. Input transients also occur when the current through the cable parasitic inductance changes abruptly. This can occur when the TPS25200 turns off the internal MOSFET in response to an overvoltage or overcurrent event. The TPS25200 can withstand the transient without a bypass bulk capacitor, or other external overvoltage protection components at input side. The TPS25200 also can be used at host side as a traditional power switch pin-to-pin compatible with the TPS2553.
