STMPS2262MTR

Overview

The STMPS2262MTR is a dual-channel high-side power distribution switch manufactured by STMicroelectronics. It integrates two N-channel MOSFETs in an 8-SOIC package, designed for robust load protection in automotive and industrial systems. The device operates within a supply voltage range of 2.7 V to 5.5 V and supports a continuous output current of 1 A per channel. Key electrical characteristics include a typical on-resistance of 105 mΩ and a fixed current limit of 1.5 A. It features comprehensive fault protection mechanisms, including over-temperature shutdown, reverse current blocking, and undervoltage lockout (UVLO). The component is rated for junction temperatures up to 125°C and utilizes a non-inverting logic interface.

Feature Summary

• Dual-channel high-side switching architecture with independent control
• Integrated thermal shutdown and fixed current limiting for overload protection
• Reverse current prevention to protect upstream power sources
• Undervoltage lockout ensures safe startup and operation

Applications

• Automotive body electronics and lighting distribution
• Industrial motor control and actuator drivers
• General-purpose load switching in embedded systems
• Power distribution units requiring short-circuit protection

Procurement Notes

Verify the specific suffix 'MTR' corresponds to the tape-and-reel packaging format required for automated assembly processes. Confirm that the 8-SOIC footprint matches the PCB layout constraints. Ensure the operating temperature range meets the environmental specifications of the final application. Cross-reference the manufacturer's latest datasheet for any updates regarding pin configuration or recommended soldering profiles.

Selection Notes

Select this component when dual-channel isolation is required within a single package to save board space. The 1 A current rating suits moderate-load applications where efficiency is balanced with cost. Consider the 105 mΩ on-resistance for power dissipation calculations under full load. Verify compatibility with the system's logic voltage levels, as the device requires a minimum operating voltage of 2.7 V.

Part Context

This part belongs to the STMPS22x2 family of enhanced dual-channel power switches from STMicroelectronics. It shares architectural similarities with the STMPS21x1 series but offers dual outputs instead of single channels. The device is designed to replace discrete MOSFET solutions, providing integrated protection features in a compact surface-mount package suitable for high-volume manufacturing.

Replacement Considerations

The STMPS2262TTR is listed as a substitute part number by distributors. Verify if the 'TTR' suffix indicates a different reel quantity or packaging variant while maintaining identical electrical specifications. No other direct cross-model replacements are confirmed in the provided documentation.
