MP5010S 5V, 1A- 5A Programmable Current Limit Switch DESCRIPTION FEATURES The MP5010S is a protection device designed to Wide 3.6V-to-18V Operating Input Range protect circuitry on the output (source) from Integrated 40m Power FET transients on input (V ). It also protects V from CC CC Enable/Fault Pin undesired shorts and transients coming from the Adjustable Slew Rate for Output Voltage source. Adjustable Current Limit At start up, inrush current is limited by limiting the Thermal Protection 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 Wireless Modem Data Cards still receive 1.1ms ramp time at the source. PC Cards The maximum load at the output (source) is Laptops current limited. This is accomplished by utilizing a All MPS parts are lead-free and adhere to the RoHS directive. For MPS green sense FET topology. The magnitude of the status, please visit MPS website under Products, Quality Assurance page. current limit is controlled by an external resistor MPS and The Future of Analog IC Technology are Registered Trademarks of Monolithic Power Systems, Inc. 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 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 MP5010S Rev. 1.0 www.MonolithicPower.com 1 8/4/2013 MPS Proprietary Information.
