STMPS2242MTR

Overview

The STMPS2242MTR 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 of 500 mA per channel. It features integrated thermal protection and independent short-circuit protection with overcurrent logic outputs. The component ensures safe operation through undervoltage lockout and reverse current protection, maintaining functionality across an ambient temperature range of -40 °C to +85 °C.

Feature Summary

• Integrates two independent high-side MOSFET switches with low on-resistance for efficient power distribution.
• Provides independent short-circuit protection that limits current to a safe level and signals faults via dedicated logic outputs.
• Includes automatic thermal shutdown recovery to prevent damage during continuous heavy overloads or short circuits.
• Ensures system reliability with built-in undervoltage lockout and reverse current protection mechanisms.

Applications

• Power distribution systems requiring multiple high-side switches in a single package
• Applications involving heavy capacitive loads and potential short-circuit conditions
• Industrial control systems needing robust fault protection and thermal management

Procurement Notes

Verify the specific ordering suffix to confirm the tape and reel packaging configuration required for automated assembly processes. Ensure compatibility with standard SOIC-8 footprint dimensions and soldering profiles during procurement planning. Cross-reference the manufacturer's latest documentation to confirm RoHS compliance status and any recent product change notifications affecting the component specifications.

Selection Notes

Select this component when a dual-channel high-side switching solution is required with integrated fault protection capabilities. It is suitable for designs where space efficiency is critical due to the integration of two switches in one package. Consider the 100 mΩ on-resistance and 500 mA per channel rating to ensure adequate performance for the intended load requirements without exceeding thermal limits.

Part Context

The STMPS2242MTR belongs to the STMPS22x2 family of enhanced dual-channel power switches from STMicroelectronics. This series is engineered for applications demanding reliable power distribution with comprehensive protection features.
