TPS22953DQCR

Power Distribution Switches, Load Drivers Overview

The TPS22953DQCR is a single-channel N-channel power switch IC designed for power distribution applications. It supports an input voltage range from 700 mV to 5.7 V and delivers a continuous output current of 5 A. The device features a maximum on-resistance of 20 mOhms, ensuring efficient power transfer with minimal loss. It operates within a temperature range of -40°C to +105°C and is housed in a compact 10-WSON package measuring 3x2 mm.

Power Distribution Switches, Load Drivers Feature Summary

• Integrates reverse current protection to prevent backflow from the load side.
• Includes controlled slew rate functionality to minimize inrush current during startup.
• Provides comprehensive fault protection including over-temperature, under-voltage lockout, and auto-restart capabilities.

Power Distribution Switches, Load Drivers Applications

• Automotive infotainment systems
• Portable electronic devices
• Industrial control modules

Power Distribution Switches, Load Drivers Procurement Notes

Verify the specific suffix DQCR against the manufacturer's official datasheet to confirm the exact package dimensions and tape-and-reel specifications. Ensure compatibility with your PCB footprint design, as the WSON-10 package requires precise soldering patterns. Cross-reference the RoHS compliance status and moisture sensitivity level with current production notices before finalizing procurement orders.

Power Distribution Switches, Load Drivers Selection Notes

Select this component when a high-current 5 A load switch is required within a low-voltage system operating up to 5.7 V. The low on-resistance makes it suitable for battery-powered applications where efficiency is critical. Consider the 10-WSON package size if board space is limited compared to larger SOIC or QFN alternatives in the same product family.

Power Distribution Switches, Load Drivers Part Context

This part belongs to the Texas Instruments TPS22953 series of load switches. It shares functional similarities with other members like the TPS22954 but differs in specific electrical characteristics and packaging options. The series is designed to replace discrete MOSFET solutions, offering integrated protection features in a small form factor.

Power Distribution Switches, Load Drivers Replacement Considerations

TPS22953DSQR is a pin-compatible alternative with a different package outline (2x2 mm vs 3x2 mm). Verify thermal performance and PCB layout requirements when substituting between these variants.
