The RS31210AR from REEDSEMI is a 5V eFuse Protection Switch designed to limit current and voltage to safe levels during fault conditions. It incorporates an integrated 25mOhm pass MOSFET for efficient operation.
Key electrical features include an adjustable current limit ranging from 2A to 5A, with a typical accuracy of ±15%. It also provides an adjustable input undervoltage lockout (UVLO) threshold and a fixed overvoltage clamp set at 6.1V. Over-temperature protection is built-in for enhanced safety.
This device is suitable for applications such as server and AUX supplies, PCI and PCIe cards, and adapter-powered devices. It is available in a compact 3x3mm VSON-10 package, supporting tape and reel packaging for automated assembly.
The RS31210AR offers EN on/off control and input UVLO features. The rising slew rate of the output voltage during turn-on can be controlled by an external capacitor connected to the dV/dT pin.
