The MP5017 is a protection device designed to protect circuitry on the output from transients from the input. Also, it protects the input from unwanted shorts and transients coming from the output.
During start-up, the inrush current is controlled by limiting the slew rate at the output. The slew rate is controlled with a small capacitor at DV/DT.
The maximum load at the output is current limited. The magnitude of the current limit is controlled by an external resistor from ILIMIT to GND. By controlling the gate voltages with a pair of N-channel MOSFETs, any current flowing from the output to the input is blocked.
Under-voltage lockout (UVLO) ensures that the input is above the minimum operating threshold before the power device is turned on. If the input voltage rises above 5.8V, the output voltage is limited quickly to 5.8V. SAS/OV is used to program the input over-voltage protection threshold.
is an open-drain output that reports a fail mode (low level) when any over-current, over-temperature, or output over-voltage is detected.
The MP5017 is available in a QFN-12 (2mmx3mm) package.
