BTS500101TAEATMA1

Overview

The BTS500101TAEATMA1 is a single-channel smart high-side power switch from Infineon's Power PROFET+ family. It operates within an input voltage range of 8 V to 18 V and provides a maximum output current of 46 A with a short-circuit current limit of 135 A. The device features a typical on-resistance of 2 mOhms, ensuring efficient power distribution. It supports supply voltages of 5.8 V to 18 V or 3.1 V to 28 V for control logic. The component is housed in an HSOF-8 surface-mount package and is designed for automotive applications, operating reliably between -40°C and +150°C.

Feature Summary

• Integrates comprehensive protection mechanisms including overtemperature, overvoltage, reverse battery, and short-circuit safeguards.
• Provides diagnostic capabilities via load current sensing for system monitoring and fault detection.
• Features low on-resistance for minimized conduction losses in power distribution networks.

Applications

• Solid state relays for two-wheeler motor starters
• Automotive lighting systems
• Power distribution units in vehicle electronics

Procurement Notes

Verify the specific ordering suffix (e.g., TAEATMA1) against official Infineon documentation to confirm the exact tape-and-reel packaging configuration and moisture sensitivity level. Ensure compatibility with the target PCB footprint, specifically the HSOF-8 package dimensions. Confirm that the application environment remains within the specified thermal and voltage limits defined in the datasheet.

Selection Notes

Select this component when a single-channel high-current solution with integrated diagnostics is required for automotive loads. Compare the 46 A continuous current rating against the peak load requirements. Consider the HSOF-8 package for space-constrained designs. Evaluate the need for reverse polarity protection and short-circuit handling capabilities inherent to the PROFET+ architecture.

Part Context

This part belongs to the Power PROFET+ series, which offers enhanced diagnostic features compared to standard high-side switches. It is designed for robust performance in harsh automotive environments. The device integrates the driver, protection circuitry, and sense amplifier into a single compact semiconductor solution, simplifying system design and reducing component count.

Replacement Considerations

Check for direct pin-compatible alternatives within the BTS50010 series, such as variants with different current ratings or package options. Verify functional equivalence regarding diagnostic signal outputs and protection thresholds before substitution.
