RS31340B Small-Size eFuse
Reed Semiconductor's 10 A protection switch features an accurate current monitor and transient overcurrent blanking
Reed Semiconductor's RS31340B is a 2.97 V to 16 V active circuit protection device with an integrated MOSFET that limits the current and voltage to safe levels during fault conditions. The current limit level is set with a resistor between the load current monitor (ILM) and ground. The RS31340B offers overvoltage protection, limiting the output voltage to a fixed level or cutting off the output when an input overvoltage fault occurs.
- Wide input voltage range: 2.97 V to 16 V
- Integrated 5.8 mΩ pass MOSFET
- Fast overvoltage protection
- Adjustable overvoltage lockout (UVLO)
- Overcurrent protection with an ILM output

- Adjustable transient blanking timer (ITIMER) for a high transient current
- Adjustable current limit range: 1.5 A to 11 A
- Fast trip response for short-circuit protection
- Adjustable output slew rate (dVdt)
- Enable with an adjustable input UVLO threshold
- Built-in overtemperature protection
- Fault (FLT) indication or power-good (PG) indication
- RoHS-compliant and green
- Hot-swap and hot-plugs
- PCI®/PCIe® cards
- Appliances and power tools
- Smartphones and tablets
- Industrial systems
