STMPS2252MTR

Overview

The STMPS2252MTR is a dual-channel high-side power distribution switch manufactured by STMicroelectronics. It integrates two independent 100 mΩ MOSFET switches within an 8-SOIC package, designed for robust power management in systems prone to heavy capacitive loads and short circuits. The device operates with a supply voltage range of 2.7 V to 5.5 V and supports continuous output currents up to 500 mA per channel. Key electrical parameters include a maximum on-resistance of 130 mΩ, a fixed current limit of 1.5 A, and a typical rise time of 2.5 ms. It functions reliably across an ambient temperature range of -40°C to +85°C.

Feature Summary

• Integrates dual high-side MOSFET switches with low on-resistance for efficient power distribution.
• Provides independent short-circuit protection with overcurrent logic output signaling.
• Features automatic thermal shutdown recovery to prevent damage from continuous overloads.
• Includes reverse current protection and undervoltage lockout for system stability.

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 suffix MTR against official datasheets to confirm tape-and-reel packaging and pin configuration. Ensure compatibility with 8-SOIC footprint requirements. Cross-reference RoHS compliance status and moisture sensitivity levels prior to integration. Confirm that the 500 mA per channel rating aligns with load specifications.

Selection Notes

Select this component when dual-channel high-side switching is required within a compact surface-mount form factor. It is suitable for designs needing integrated fault protection without external discrete components. Consider the 2.7 V to 5.5 V operating range for logic compatibility. Evaluate thermal dissipation capabilities if continuous operation near current limits is expected.

Part Context

This part belongs to the STMPS22x2 family of enhanced dual-channel power switches from STMicroelectronics. The series is engineered for applications demanding reliable power distribution under harsh electrical conditions. Variants within the family differ primarily in current ratings and package types, sharing common protection features like thermal shutdown and reverse current blocking.
