MP5010B 3V-18V, 1A-5A Programmable-Current- Limit Switch with Over-Voltage Clamp The Future of Analog IC T echnology DESCRIPTION FEATURES The MP5010B is a protection device designed to Wide 3V-to-18V Operating Input Range protect circuitry on the output (source) from 5.7V Output Over-Voltage Clamp transients on the input (V ). It also protects the CC Integrated 40m Power FET input from undesired shorts and transients Enable/Fault Pin coming from the source. Adjustable Output Voltage Slew Rate A small capacitor on the dv/dt pin controls the Adjustable Current Limit slew rate that limit the inrush current at the Thermal Protection source. For instance, a 1nF capacitor results in a source ramp-up time of 3ms. APPLICATIONS The maximum load at the source is current Hot-Swappable Devices limited using a sense FET topology. An external Wireless Modem Data Cards resistor between the I-Limit pin and the Source PC Cards pins controls the magnitude of the current limit. Laptops An internal charge pump drives the gate of the All MPS parts are lead-free and adhere to the RoHS directive. For MPS green power device, allowing the DMOS power FET to status, please visit MPS website under Products, Quality Assurance page. have a very low ON-resistance of just 40m. MPS and The Future of Analog IC Technology are Registered Trademarks of Monolithic Power Systems, Inc. The MP5010B also protects the source from the input being too low or too high. Under-voltage lockout ensures that the input remains above the minimum operating threshold before the power device turns on. If the input rises above the high output threshold, the MP5010B limits the source voltage.
