MP5017 3V-.5.5V, 1A 5A Current Limit Switch with Over-Voltage Clamp and Reverse Blocking in 2mmx3mm QFN Package The Future of Analog IC Technology FEATURES DESCRIPTION 3V to 5.5V Continuous Operating Input The MP5017 is a protection device designed to Range protect circuitry on the output from transients 16V Absolute Maximum Input Voltage from the input. Also, it protects the input from Output Discharge unwanted shorts and transients coming from the output. SAS/OV Disable to Support DEVSLP or POWER DOWN During start-up, the inrush current is controlled 5.8V Fast Output OVP Response by limiting the slew rate at the output. The slew Reverse Current Blocking rate is controlled with a small capacitor at Integrated 45m R Power FET DS(ON) DV/DT. Adjustable Current-Limit through ILIMIT The maximum load at the output is current 210 A Low Quiescent Current limited. The magnitude of the current limit is Programmable Soft-Start Time through controlled by an external resistor from ILIMIT to DV/DT GND. By controlling the gate voltages with a Fast Response for Hard-Short Protection pair of N-channel MOSFETs, any current Fault Indication for Over-Current, Over- flowing from the output to the input is blocked. Temperature, and Output Over-Voltage Under-voltage lockout (UVLO) ensures that the OTP Auto-Retry with 76ms Recovery input is above the minimum operating threshold Delay before the power device is turned on. If the Available in a QFN-12 (2mmx3mm) input voltage rises above 5.8V, the output Package voltage is limited quickly to 5.8V. SAS/OV is APPLICATIONS used to program the input over-voltage protection threshold. HDD and SSD Hot Swap is an open-drain output that reports a fail Fault Wireless Modem Data Cards mode (low level) when any over-current, over- PC Cards temperature, or output over-voltage is detected. USB Power Distribution The MP5017 is available in a QFN-12 All MPS parts are lead-free, halogen-free, and adhere to the RoHS directive. For (2mmx3mm) package.
