MP5002 - 1A-3A Programmable Current Limit Switch

General Description

The MP5002 is a protection device designed to protect circuitry on the output (VOUT) from transients on the input (VIN).

It also protects VIN from undesired shorts and transients coming from the load.

At start up, inrush current is limited by limiting the slew rate at VOUT.

Key Features

  • Integrated 44mΩ Power FET.
  • Enable/Fault Pin.
  • Adjustable Slew Rate for Output Voltage.
  • Adjustable Current Limit: 1A-3A.
  • Thermal Protection.
  • Over Voltage Limit.

The Future of Analog IC Technology MP5002 3.3V, 1A-3A Programmable Current Limit Switch DESCRIPTION The MP5002 is a protection device designed to protect circuitry on the output (VOUT) from transients on the input (VIN). It also protects VIN from undesired shorts and transients coming from the load. At start up, inrush current is limited by limiting the slew rate at VOUT. The slew rate is controlled by a small capacitor at the dv/dt pin. The dv/dt pin has an internal circuit that allows the customer to float this pin (no connect) and still receive a 1.1ms ramp time at VOUT. The max load at the output (VOUT) is current limited. This is accomplished by utilizing a sense FET topology. The magnitude of the current limit is controlled by an external resistor connected between the ILIMIT pins.
