Overview
The STMPS2141MTR is a single-channel high-side power distribution switch manufactured by STMicroelectronics. It integrates a 90 mΩ N-channel MOSFET controlled by a logic enable input, designed for applications involving heavy capacitive loads and short circuits. The device operates within a supply voltage range of 2.7 V to 5.5 V and supports a continuous output current of 500 mA with an 800 mA current limit. It features fixed overcurrent protection, thermal shutdown with automatic recovery, reverse current protection, and undervoltage lockout (UVLO). The component is housed in an 8-SOIC surface-mount package.
Feature Summary
- Integrates a low-resistance N-channel MOSFET for efficient high-side power switching
- Provides active overcurrent limiting and thermal protection with automatic restart capability
- Includes reverse current protection and undervoltage lockout for system stability
Applications
- Power distribution in systems with heavy capacitive loads
- Protection against short-circuit conditions in load drivers
- General-purpose power switching in consumer electronics
Procurement Notes
Verify the specific suffix 'MTR' corresponds to the required tape-and-reel packaging configuration. Confirm that the 8-SOIC footprint matches the target PCB layout. Ensure the operating temperature range meets the environmental requirements of the final assembly. Cross-reference the manufacturer part number with official distributor catalogs to validate authenticity and current production status before procurement.
Selection Notes
Select this component when a single-channel high-side switch with integrated fault protection is required. It is suitable for designs needing CMOS or TTL compatible control inputs. Consider the 90 mΩ on-resistance for efficiency calculations. Verify that the 500 mA continuous current rating satisfies the load requirements. Ensure the 2.7 V to 5.5 V supply voltage aligns with the system power rails.
Part Context
This device belongs to the STMPS21xx series of enhanced single-channel power switches from STMicroelectronics. The series is engineered for robust performance in environments prone to electrical stress. Other models in the family may offer different current ratings or pin configurations while sharing similar protection architectures.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Consult manufacturer cross-reference tools for potential alternatives.
