BTS500151TAAATMA1

Overview

The BTS500151TAAATMA1 is a single-channel high-side power switch from Infineon's Power PROFET series, designed for automotive load distribution. It features an N-channel output with a maximum continuous current of 33 A and a peak current limit of 135 A. The device operates within a supply voltage range of 8 V to 18 V and supports load voltages up to 28 V. Key electrical parameters include a maximum on-resistance of 3 mOhms, a maximum turn-on time of 700 us, and a maximum turn-off time of 700 us. It is housed in a PG-TO263-7-8 surface-mount package and rated for junction temperatures between -40°C and +150°C.

Feature Summary

• Integrates comprehensive protection mechanisms including fixed current limiting, overtemperature shutdown, and overvoltage protection.
• Provides diagnostic capabilities via integrated fault detection and status reporting for system monitoring.
• Features a non-inverting input interface for straightforward control logic integration.

Applications

• Automotive battery management systems
• High-side power distribution units
• Load switching for automotive actuators

Procurement Notes

Verify component authenticity through authorized channels due to the prevalence of counterfeits in the semiconductor market. Confirm that the received part matches the specific ordering suffix ATMA1 to ensure correct packaging and tape-and-reel specifications. Check RoHS compliance documentation if required by local regulations. Ensure storage conditions adhere to moisture sensitivity level 3 requirements prior to soldering.

Selection Notes

Select this component when a single-channel high-side switch with high current capability is required. The 33 A rating suits heavy loads compared to lower-current alternatives. Consider the TO-263-7 package for thermal performance needs. Verify that the 135 A peak current limit aligns with inrush or short-circuit scenarios in the target application circuit design.

Part Context

This part belongs to the BTS50015 family of smart high-side switches. It shares architectural similarities with variants like BTS50015-1TAD but differs in packaging and specific ordering codes. The Power PROFET technology integrates the driver and protection logic directly onto the silicon die, offering a compact solution for replacing discrete MOSFET and driver combinations in space-constrained automotive designs.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source data. Cross-reference with BTS50015-1TAD or BTS500151TADATMA2 only if pinout and electrical specifications are verified identical through official datasheets.
