Description
The RS31210 and RS31310 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 ILIM and ground, and the typical current limit accuracy is ±15%. The device has over voltage protection feature which limits the output voltage to a fixed level when 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 dV/dT and ground. The device also offers EN on/off control and input UVLO features. The device is available in VSON 10 pins , 3x3 mm package.
