Description
The RS31312 is active circuit protection device with 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 ISET and ground. Also, the device provides current monitor signal.
The device has input over voltage protection feature to protect output load in the event of input over voltage fault.
To limit the inrush current during device turn-on, the output soft start time can be set by a capacitor between SS and ground.
In addition, the device has adjustable fault blanking timer to avoid over-current tripping during output load transient.
The device also has load enable function and programmable LOADEN blanking time.
The device is available in QFN-22, 3×5 mm package.
Applications
- Server and AUX supplies
- PCI and PCIe cards
- Router and switch optical module
- Digital TV
