STMPS2242MTR Equivalent & Substitute Parts

Part Overview

The STMPS2242MTR is an active power management integrated circuit manufactured by STMicroelectronics, classified as a Power Switch/Driver with 1:2 output configuration. This component functions as a general-purpose power switch with dual high-side outputs, rated for 500mA maximum output current and operating across a 2.7V to 5.5V load voltage range. The device is currently in active production status with robust fault protection including current limiting, over-temperature shutdown, reverse current protection, and under-voltage lockout (UVLO). Substitute parts are identified when equivalent electrical specifications, mechanical packaging, and compliance certifications align with the original component, enabling direct replacement in circuit designs without functional degradation.

Parameter Comparison

Engineering Selection Recommendations

Both the STMPS2242MTR and STMPS2252MTR are active production components manufactured by STMicroelectronics with identical electrical and mechanical specifications. Selection between these parts is based on availability and supply chain considerations rather than functional differences.

The STMPS2242MTR is suitable for applications requiring a general-purpose power switch with dual high-side outputs in space-constrained surface-mount designs. The component's 500mA output current capacity, 105mOhm typical on-resistance, and comprehensive fault protection (current limiting, over-temperature shutdown, reverse current protection, and UVLO) address standard power distribution and load switching requirements across 2.7V to 5.5V systems.

Both parts maintain ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1), supporting deployment in standard manufacturing and storage environments without special handling requirements. The 8-SOIC package format enables integration into standard PCB assembly processes.
