Product Description

The MP5036A is a protection device designed to protect circuitry on the output from transients on the input, while simultaneously protecting the input from undesired shorts and transients from the output.

The DV/DT pin controls the slew rate at the output. The slew rate limits the inrush current during start-up.

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. There is a fixed, 2.5A current limit when floating the ILIMIT pin.

The output voltage is limited by the output’s over-voltage protection (OVP) function.

The device is available in a TSOT23-6 package.

5V, 0.4A-5A Current Limit Switch with Over Voltage Clamp

The EV5036A-J-00A Evaluation Board is designed to demonstrate the capabilities of MPS’ MP5036A, a protection device designed to protect circuitry on the output from transients on input. It also protects input from undesired shorts and transients coming from the output. MP5036A is a small RON, low quiescent current, current limited switch.

At startup, the inrush current is limited by limiting the slew rate at the output. The slew rate is controlled by a capacitor at the DV/DT pin.

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. There is a fixed 2.5A current limit when floating ILIMIT pin.

The output voltage is limited by the output over voltage protection (OVP) function.

The MP5036A is available in a space-saving 8 pin-TSOT23-6 package.
