MP5036GJ-P

Overview

The MP5036GJ-P is a power switch IC designed for power distribution, featuring a 12V rating and an integrated current limit switch with overvoltage clamp capabilities. It operates within a continuous input voltage range of 2.9V to 14V, supporting a maximum absolute transient input voltage of 26V. The device incorporates a fixed overvoltage clamp threshold at 15V and provides programmable soft-start functionality via the DV/DT pin. Current limiting is adjustable through an external resistor on the ILIMIT pin or set to a fixed 2.5A when the pin is left floating. Packaged in a TSOT-23-6 format, it includes an integrated 43mΩ power FET.

Feature Summary

• Integrates fast output overvoltage protection with a fixed 15V clamp threshold to safeguard downstream circuits from input transients.
• Provides automatic recovery from overcurrent conditions and thermal shutdown protection to enhance system reliability.
• Features programmable soft-start control via the DV/DT pin to limit inrush current during startup sequences.

Applications

• Power distribution networks requiring transient protection
• Load switching applications with defined current limits
• Systems needing overvoltage clamping on output lines

Procurement Notes

Verify the specific suffix 'P' corresponds to the required tape-and-reel packaging configuration as indicated by distributor listings. Confirm that the TSOT-23-6 package dimensions align with the target PCB footprint constraints. Ensure the operating temperature range of -40°C to +125°C meets the environmental requirements of the final assembly. Cross-reference the manufacturer datasheet for any recent design revisions or recommended soldering profiles.

Selection Notes

Select this component when a compact solution is needed for protecting loads against input surges and short circuits. It is suitable for designs requiring adjustable current limiting without complex external circuitry. Consider the 43mΩ internal resistance for efficiency calculations under high-load conditions. Evaluate the need for programmable soft-start to manage capacitive loads effectively during power-up phases.

Part Context

This part belongs to the Monolithic Power Systems MP5036 family of load switches. These devices are engineered to provide robust protection for sensitive electronics against electrical faults. The series emphasizes compact integration, combining switching, limiting, and protection functions into a single small-footprint package. This approach simplifies bill-of-materials and reduces board space compared to discrete solutions.

Replacement Considerations

The MP5036GJ-Z is listed as a variant within the same product line. Verify if the suffix change impacts packaging or specific manufacturing lot characteristics before substitution. No other direct cross-model substitutes are confirmed in the provided documentation.
