Description
The RS31330/331/332 devices are active circuit protection devices 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 ILM and ground.
The device has over voltage protection feature which either limits the output voltage to a fixed level or cuts off the output when input over voltage fault occurs.
To limit the inrush current during device turn-on, the rising slew rate of output voltage can be set by a capacitor between dVdt and ground.
The device also offers EN on/off control and input UVLO features.
The device is available in QFN-10 pins, 2×2 mm package.
Applications
- Server, PC mother board
- PCI and PCIe cards
- Appliances and power tools
- Smartphones and tablets
- Industrial system
