Overview
The STMPS2151TTR is an enhanced single-channel high-side power distribution switch manufactured by STMicroelectronics. It incorporates a 90 mΩ N-channel MOSFET for efficient power switching. The device operates within a voltage range of 2.7 V to 5.5 V and supports a continuous output current of 500 mA. It features a maximum standby supply current of 12 μA and includes undervoltage lockout (UVLO). The component is designed for applications involving heavy capacitive loads and short circuits, providing thermal protection and reverse current protection.
Feature Summary
- High-side power switch with low on-resistance
- Integrated thermal and short-circuit protection
- CMOS and TTL compatible enable input
- Reverse current protection capability
Applications
- Power management systems
- Applications with heavy capacitive loads
- Circuits requiring short-circuit protection
Procurement Notes
Verify the specific suffix 'TTR' against official STMicroelectronics documentation to confirm tape and reel packaging specifications. Ensure the part number matches the exact electrical characteristics required for the design, particularly the 500 mA current rating and 90 mΩ on-resistance. Cross-reference the datasheet for any updates regarding UL recognition or environmental compliance status before finalizing procurement.
Selection Notes
Select this component when a single-channel high-side switch with integrated protection is required. It is suitable for designs needing CMOS/TTL logic control and operation within a 2.7 V to 5.5 V supply range. Consider the SOT-23-5 package constraints and the 500 mA continuous current limit. Verify that the thermal dissipation capabilities meet the application's overload conditions.
Part Context
The STMPS2151TTR belongs to the STMPS21x1 family of enhanced single-channel power switches from STMicroelectronics. This series is designed for robust power distribution in environments prone to overloads. The TTR suffix typically indicates a specific tape and reel packaging format for automated assembly, distinguishing it from other package variants like STR.
Replacement Considerations
Consult official STMicroelectronics resources for confirmed substitute part numbers. Generic cross-references may not match the specific 90 mΩ resistance or protection thresholds.
