The TPS25200-Q1 device is a 5-V eFuse with a precision current-limit and overvoltage clamp. The device provides robust protection for load and source during overvoltage and overcurrent events. The TPS25200-Q1 device is an intelligent protected load-switch with a VINvalue tolerant to 20 V. In the event that an incorrect voltage is applied at the IN pin, the output clamps to 5.4 V to protect the load. If the voltage at the IN pin exceeds 7.6 V, the device disconnects the load to prevent damage to the device, load, or both. The TPS25200-Q1 device has an internal 67-mΩ power switch and is intended for protecting the source, device, and load under a variety of abnormal conditions. The device provides up to 2.4 A of continuous load current. The current-limit is programmable from 85 mA to 2.7 A with a single resistor to ground. During overload events, the output current is limited to the level set by the RILIMresistor. If a persistent overload occurs, the device eventually enters thermal shutoff to prevent damage to the TPS25200-Q1 device.

The TPS2521x family of eFuses is a highly integrated circuit protection and power management solution in a small package. The devices provide multiple protection modes using very few external components and are a robust defense against overloads, short-circuits, voltage surges, reverse polarity and excessive inrush current. With integrated back-to-back FETs, reverse current flow from output to input is blocked at all times, making the device well suited for systems which need load side energy hold up storage in case input power supply fails. Output current limit level can be set with a single external resistor. It is also possible to get an accurate sense of the output load current by measuring the voltage drop across the current limit resistor. Applications with particular inrush current requirements can set the output slew rate with a single external capacitor. Loads are protected from input overvoltage conditions by clamping the output to a safe fixed maximum voltage (pin selectable). The devices are available in a 2-mm × 2-mm, 10-pin HotRod QFN package for improved thermal performance and reduced system footprint.
