The MP5000S is a protection device designed to protect circuitry on the output source from transients on input VCC. It also protects VCC from undesired shorts and transients coming from the source.At start up, inrush current is limited by limiting the slew rate at the source. The slew rate is controlled by a small capacitor at the dv/dt pin. The dv/dt pin has an internal circuit that allows the customer to float this pin no connect and still receive 0.9ms ramp time at the source.The maximum load at the output source is current limited. This is accomplished by utilizing a sense FET topology. The magnitude of the current limit is controlled by an external resistor from the I-Limit pin to the Source pin.An internal charge pump drives the gate of the power device, allowing a very low on-resistance DMOS power FET of just 40mΩ.The source is protected from the VCC input being too low or too high. Under Voltage Lockout UVLO assures that VCC is above the minimum operating threshold, before the power device is turned on. If VCC goes above the high output threshold, the source voltage will be limited.
