STMPS2272MTR

Overview

The STMPS2272MTR is an enhanced dual-channel high-side power switch IC manufactured by STMicroelectronics. It integrates two N-channel MOSFETs in a single package to provide robust power distribution for loads up to 1A per channel. The device operates within a supply voltage range of 2.7V to 5.5V and features a low on-resistance of approximately 105mΩ. It includes comprehensive protection mechanisms such as fixed current limiting, thermal shutdown, reverse current blocking, and undervoltage lockout (UVLO). The component is housed in an 8-SOIC surface-mount package.

Feature Summary

• Dual-channel architecture providing independent control of two high-side power switches
• Integrated fault protection including overcurrent limiting, thermal shutdown, and reverse current prevention
• CMOS and TTL compatible logic inputs for straightforward interface with microcontrollers

Applications

• Power distribution units requiring dual isolated outputs
• Embedded systems managing multiple peripheral power rails
• Industrial controllers handling heavy capacitive loads

Procurement Notes

Verify the specific suffix MTR indicates tape and reel packaging when sourcing components. Confirm that the 8-SOIC footprint matches your PCB layout requirements. Ensure the operating temperature range aligns with your system's environmental conditions. Cross-reference the manufacturer part number directly with official STMicroelectronics documentation to avoid counterfeit or obsolete variants.

Selection Notes

Select this component when dual-channel power switching is required within a compact surface-mount form factor. It is suitable for applications needing integrated protection against short circuits and thermal overload without external discrete components. Consider the 1A continuous current rating per channel to ensure adequate headroom for your specific load requirements.

Part Context

This device belongs to the STMPS22x2 family of enhanced power distribution switches from STMicroelectronics. It shares architectural similarities with single-channel variants like the STMPS2171 but offers doubled output capacity. The series is designed for general-purpose power management in consumer and industrial electronics where space efficiency and reliability are critical.
