STMPS2262TTR

Overview

The STMPS2262TTR is an enhanced dual-channel high-side power distribution switch manufactured by STMicroelectronics. It integrates two independent 100 mΩ MOSFET switches designed for applications involving heavy capacitive loads and short-circuits. The device operates within a voltage range of 2.7 V to 5.5 V and supports continuous currents up to 1 A per channel. Key electrical parameters include a maximum on-resistance of 120 mΩ, a typical rise time of 2.5 ms, and a maximum standby supply current of 13 μA. It features thermal protection with automatic recovery and undervoltage lockout.

Feature Summary

• Integrates two independent high-side MOSFET switches with low on-resistance for efficient power distribution.
• Provides comprehensive fault protection including fixed current limiting, thermal shutdown with auto-recovery, reverse current protection, and undervoltage lockout.
• Features independent overcurrent logic output to signal short-circuit or overload conditions.
• Compatible with CMOS and TTL logic inputs for straightforward control interface.

Applications

• Power distribution systems requiring multiple switches in a single package
• Applications subject to heavy capacitive loads
• Systems prone to short-circuit events

Procurement Notes

Verify the specific suffix 'TTR' corresponds to the MSOP-8 tape and reel packaging configuration as indicated by distributor data. Confirm that the operating temperature range aligns with your system requirements, noting variations between -40°C to +85°C and extended junction temperatures depending on the specific datasheet revision. Ensure compatibility with the 2.7 V to 5.5 V supply voltage range for your application design.

Selection Notes

Select this component when a dual-channel solution is required for high-side switching with integrated protection. It is suitable for designs needing independent control of two loads with short-circuit and thermal safeguards. Consider the MSOP-8 package size for space-constrained PCB layouts. Verify that the 1 A continuous current rating per channel meets the load requirements and that the 100 mΩ on-resistance provides acceptable power dissipation levels.

Part Context

The STMPS2262TTR belongs to the STMPS22x2 series of enhanced dual-channel power switches from STMicroelectronics. This family includes variants like the STMPS2242, STMPS2252, and STMPS2272, which share similar architectural features but may differ in specific current ratings or package options. The TTR suffix typically denotes the reel packaging format used for automated assembly processes.
