Littelfuse LS0504EVT233 Protection eFuse IC

Littelfuse LS0504EVT233 Protection eFuse IC offers a 2.7V to 6V input voltage range, 30V maximum input/output voltage, and a 4A peak current. This IC features an integrated load switch that provides robust, input overcurrent protection to the downstream circuit systems. This device comes with built-in overvoltage protection (OVP), an internal soft start, and low RDS(ON) that minimizes the system's power loss. In the event of input overvoltage, the LS0504EVT233 immediately turns off the switch, preventing the downstream system from the stress of excessively high voltage. Littelfuse LS0504EVT233 Protection eFuse IC is suitable for BLUETOOTH® headsets, tablet PCs, charging cables, and adapter-powered devices.
