RS31385 High-Current eFuse

Reed Semiconductor's 5 mm x 5 mm stackable 50 A eFuse has hot-swap protection and current monitoring

Image of Reed Semiconductor's RS31385 High Current eFuse Reed Semiconductor's RS31385 is an active circuit protection device with an integrated MOSFET used to limit current and voltage to safe levels during fault conditions. The current limit level can be set with a resistor between CLREF and ground. Also, the device has integrated current sense and provides a current monitor signal.
