About This Product

■Summary

The MP5017A is a protection device designed to protect output circuitry from input transients. It also protects the input from unwanted shorts and transients at the output. During start-up, inrush current is controlled by limiting the output slew rate. The slew rate is controlled by a small capacitor connected to the DV/DT pin. Maximum output load is current limited. The magnitude of the current limit (ILIMIT) is controlled by an external resistor connected between the ILIMIT and GND pins. By controlling the gate voltage through a pair of N-channel MOSFETs, any current flowing from the output to the input is blocked. Undervoltage lockout (UVLO) protection ensures that inputs are above minimum operating thresholds before the device starts. When the input voltage (VIN) exceeds 5.8V, the output voltage (VOUT) is limited to 5.8V. The SAS/OV pin programs the VIN overvoltage protection (OVP) threshold. The FAULT pin is an open-drain output that goes low when an overcurrent (OC), overtemperature (OT), or output overvoltage (OV) fault is detected. MP5017A is available in a QFN-12 (2mm x 3mm) package.

■Features and benefits

・Wide operating input voltage (VIN) range from 3V to 5.5V ・16V absolute maximum VIN ・Output discharge - SAS/OV is disabled to support DEVSLP or POWER_DOWN ・8V high-speed output overvoltage protection (OVP) response ・Reverse current cutoff ・Integrated 45mΩ RDS (ON) power MOSFET ・Adjustable current limit via ILIMIT (ILIMIT) ・Low quiescent current (IQ) of 210μA ・Configurable soft start time (tSS) via DV/DT ・Fast response with hard short protection - Fault indication for overcurrent (OC), overtemperature (OT), and output overvoltage (OV) conditions ・Over-temperature protection (OTP) automatic retry with 76ms recovery delay ・Provided in QFN-12 (2mm x 3mm) package

■Available product numbers

・MP5017AGD-Z MP5017AGD-P ・Part numbers ending in P and Z are the same part. P and Z indicate reel size only
