Product Description

The MP5006 is a protection device designed to protect circuitry on the output (VOUT) from transients on input (VIN). It also protects VIN from undesired shorts and transients coming from the load. At start up, inrush current is controlled by limiting the slew rate at the VOUT. 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 receives a 1.4ms ramp time at the VOUT. The max load at the output (VOUT) is current limited. This is accomplished by utilizing a sense FET topology. The magnitude of the current limit is controlled by an external resistor connected between the ILIMIT pins. An internal charge pump drives the gate of the power device, allowing a very low on-resistance DMOS power FET of just 0.07O. VOUT is protected from VIN being too low or too high. Under Voltage Lockout (UVLO) assures that the input is above the minimum operating threshold, before the power device is turned on. If VIN goes above the high output threshold, the output voltage will be limited.
