STMPS2252TTR

Overview

The STMPS2252TTR is a dual-channel high-side power distribution switch manufactured by STMicroelectronics, designed for robust power management in systems prone to heavy capacitive loads and short circuits. It integrates two independent 100 mΩ MOSFET switches within an 8-MSOP-EP package. The device operates with a load voltage range of 2.7 V to 5.5 V and supports a maximum continuous output current of 500 mA per channel. It features non-inverting logic inputs compatible with CMOS and TTL standards. Key protection mechanisms include fixed current limiting, thermal shutdown with automatic recovery, reverse current protection, and undervoltage lockout (UVLO). An overcurrent logic output provides fault indication.

Feature Summary

• Integrates two independent high-side MOSFET switches with low on-resistance for efficient power distribution.
• Provides comprehensive fault protection including fixed current limiting, thermal shutdown, reverse current blocking, and undervoltage lockout.
• Features an open-drain overcurrent logic output to signal fault conditions such as short circuits or overload events.
• Supports automatic recovery from thermal shutdown once the junction temperature decreases to safe levels.

Applications

• Power distribution systems requiring multiple switches in a single package
• Applications involving heavy capacitive loads
• Systems susceptible to short-circuit conditions

Procurement Notes

Verify the specific ordering suffix to ensure the correct packaging configuration matches your assembly requirements. Confirm that the component meets RoHS3 compliance standards if required by your manufacturing regulations. Check the latest datasheet revision to ensure all electrical characteristics and pin configurations remain consistent with your design specifications before finalizing procurement.

Selection Notes

Select this component when designing circuits that require dual high-side switching with integrated protection features. Ensure the input logic levels are compatible with your control interface, as the device accepts non-inverting signals. Consider the thermal performance of the 8-MSOP-EP package in your layout, as the exposed pad aids in heat dissipation during overcurrent or thermal shutdown events. Verify that the load voltage stays within the specified 2.7 V to 5.5 V range.

Part Context

The STMPS2252TTR belongs to the STMPS22x2 family of enhanced dual-channel power switches from STMicroelectronics. This series is engineered for applications demanding reliable power distribution under harsh electrical conditions. The TTR suffix indicates the device is supplied in tape and reel format, suitable for automated surface-mount assembly processes. It shares functional similarities with other members of the STMPS22xx family but is distinguished by its specific current rating and package type.

Replacement Considerations

Direct substitutes within the same family include STMPS2242, STMPS2262, and STMPS2272, which offer similar dual-channel functionality but may differ in current ratings or specific protection thresholds. When replacing, verify that the alternative part number maintains compatibility with the 8-MSOP-EP package and the 2.7 V to 5.5 V operating voltage range to ensure seamless integration without redesigning the PCB footprint or control logic.
