TPS27S100BPWPT

Power Distribution Switches, Load Drivers Overview

The TPS27S100BPWPT is a single-channel industrial high-side power switch from Texas Instruments, housed in a 14-pin HTSSOP (PWP) package. It supports an operating voltage range of 3.5 V to 40 V and delivers a continuous output current of 4 A with a maximum on-resistance of 80 mΩ. The device features adjustable current limiting between 500 mA and 6 A and includes an analog current monitor output. It operates within a temperature range of -40°C to 125°C and holds AEC-Q100 qualification for automotive applications.

Power Distribution Switches, Load Drivers Feature Summary

• Provides analog current monitoring capability via a dedicated output pin
• Features adjustable current limit settings for flexible load protection
• Includes comprehensive fault protection against overloads, short circuits, and over-temperature conditions

Power Distribution Switches, Load Drivers Applications

• Automotive power distribution systems
• Industrial load switching applications
• High-side power management in vehicle electronics

Power Distribution Switches, Load Drivers Procurement Notes

Verify the specific suffix 'BPWPT' to confirm the presence of the analog current monitor feature, as the 'A' variant offers open-drain status instead. Ensure the order quantity matches the tape-and-reel packaging format typically associated with this suffix. Confirm AEC-Q100 compliance requirements if deploying in qualified automotive environments. Cross-reference the datasheet revision date to ensure compatibility with latest thermal and electrical specifications.

Power Distribution Switches, Load Drivers Selection Notes

Select this component when analog feedback of load current is required for system diagnostics or closed-loop control. Choose over the TPS27S100A variant if status indication alone is insufficient for the application's monitoring needs. Consider the 80 mΩ on-resistance for efficiency calculations at 4 A loads. Verify that the 14-pin HTSSOP package fits the PCB footprint constraints and thermal dissipation requirements of the design.

Power Distribution Switches, Load Drivers Part Context

This part belongs to the TPS27S100x family of single-channel high-side switches designed for robust power distribution. It complements other variants like the TPS27S100APWPT by offering enhanced diagnostic capabilities through analog signaling rather than digital status flags. The series targets both industrial and automotive sectors requiring reliable, protected switching solutions.

Power Distribution Switches, Load Drivers Replacement Considerations

The TPS27S100APWPT serves as a functional substitute but provides an open-drain status output instead of an analog current monitor. Verify if the application requires analog feedback; if not, the 'A' variant may be interchangeable. Both share similar electrical ratings and package dimensions.
