IS6103D is an active active circuit protection device that integrates field-effect transistors (FETs). With the hot-swappable design, the current and voltage can be limited within the safe range even in the event of a failure. This device features the Auto Retry Fault Response function, which can effectively prevent overloading, short circuits, voltage surges, overcurrents and reverse currents. Its built-in clamping circuit, without the need for external components, can limit overvoltage to the safe maximum value, providing overvoltage protection (OVP) for 12V systems. When a specific voltage ramp is required, the dV/dT pin can be programmed and set using a single capacitor to ensure that the output curve meets the specifications. This device supports programmable current limiting function. The current limiting value is set by connecting the ILIMIT pin to the ground through an external resistor, with an accuracy of ±15%. And only a single external resistor is required to complete the parameter configuration.
