The MP5026 is a hot-swap protection device designed to protect circuitry on its output from transients on its input. It also protects its input from undesired shorts and transients coming from its output. The device can achieve up to 20A of continuous output current (I_OUT) per device at room temperature.

The device limits the power supply voltage drop by limiting the inrush current to the load while a circuit card is inserted into a live backplane power source. It limits the internal MOSFET current (I_FET) by controlling the gate voltage (V_GATE) via a low-power resistor from ISET to ground and the soft-start ramp.

The MP5026 provides many features to simplify system design, such as an integrated current mirror to monitor I_OUT and integrated on-die temperature-sensing. It eliminates the demand for an external current-sense power resistor, power MOSFET, and temperature-sense device.

The maximum load at the output is current-limited through the sensing FET topology. The current-limit level is controlled by a low-power resistor from ISET to ground.

The MP5026 provides diverse fault protections, including over-current protection (OCP), short-circuit protection (SCP), over-temperature protection (OTP), damaged MOSFET detection, over-voltage protection (OVP), and under-voltage protection (UVP).

The MP5026 is available in an LGA-26 (4mmx4mm) package.
