TPS259261DRCT

The purpose of the TPS25925x/6x family of eFuses is to provide integrated circuit protection and power management in a tiny package. These devices offer protection against overloads, shorts circuits, voltage surges, excessive inrush current, and reverse current. They require few external components and offer multiple protection modes, making them a robust defense against various electrical issues. The current limit level can be set with a single external resistor, and the devices have a typical accuracy of ±15%. Additionally, they feature fixed over-voltage clamps and adjustable current limits, providing flexibility in different applications. [1]

The current limit level for the TPS25925x/eFuses can be set with a single external resistor, and the current limit set has a typical accuracy of ±15%. The current limit is set to IOL (over-load current limit) during normal operation. When power dissipation in the internal MOSFET exceeds 10W, there is a thermal foldback in the current limit value, causing IOL to drop to ISC. In each of these modes, the MOSFET gate voltage is regulated to throttle short-circuit and overload current flowing to the load. Eventually, the device shuts down due to over temperature. [3]
