MP5017A
DESCRIPTION
The MP5017A is a protection device designed to protect circuitry on the output from transients from the input. It also protects the input from unwanted shorts and transients ing 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 the DV/DT pin.
The maximum load at the output is currentlimited. The magnitude of the current limit is controlled by an external resistor placed between ILIMIT and 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 device is turned on. If the input voltage (VIN) exceeds 5.8V, the output voltage (VOUT) is quickly limited to 5.8V. SAS/OV is used to program the input over-voltage protection (OVP) threshold. FAULT is an opendrain output that reports a fault...
