MP5000A 12V, 5A Programmable Current Limit Switch The Future of Analog IC Technology DESCRIPTION FEATURES Integrated 40m Power FET The MP5000A is a protection device designed to Enable/Fault Pin protect circuitry on the output (source) from Adjustable Slew Rate for Output Voltage transients on input (V ). It also protects V from CC CC undesired shorts and transients coming from the Adjustable Current Limit: 1-5A source. Thermal Protection Over Voltage Limit At start up, inrush current is limited by limiting the Low Inrush Current slew rate at the source. The slew rate is controlled by a small capacitor at the dv/dt pin. APPLICATIONS The dv/dt pin has an internal circuit that allows Hot Swap the customer to float this pin (no connect) and PC Cards still receive 0.9ms ramp time at the source. Laptops The maximum load at the output (source) is All MPS parts are lead-free and adhere to the RoHS directive. For MPS green current limited. This is accomplished by utilizing a status, please visit MPS website under Products, Quality Assurance page. sense FET topology.

An internal charge pump drives the gate of the power device, allowing a very low on-resistance DMOS power FET of just 40m. The source is protected from the V input being CC too low or too high. Under Voltage Lockout (UVLO) assures that V is above the minimum CC operating threshold, before the power device is turned on. If V goes above the high output CC threshold, the source voltage will be limited. TYPICAL APPLICATION MP5000A Rev. 1.01 www.MonolithicPower.com 1 10/16/2014 MPS Proprietary Information.
