BTS452TXT Equivalent & Substitute Parts

Part Overview

The BTS452TXT is a Power Management Integrated Circuit (PMIC) manufactured by Infineon Technologies, specifically a power switch driver with 1:1 N-Channel configuration rated for 1.8A output current. This component operates as a high-side switch with on/off interface control, designed for automotive-grade applications with AEC-Q100 qualification. The BTS452TXT is classified as obsolete, making identification of active equivalent parts essential for ongoing design support and procurement continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the BTS452TXT is determined by strict equivalence across the following critical parameters:

• Electrical specifications: 1:1 input-output ratio, N-Channel high-side output configuration, 1.8A maximum output current, 150mOhm typical on-resistance, 6V to 52V load voltage range
• Control interface: On/off non-inverting input type
• Protection features: Current limiting (fixed), over-temperature, and over-voltage fault protection with auto-restart capability
• Thermal and operational range: -40°C to 150°C junction temperature
• Automotive compliance: AEC-Q100 qualification and automotive grade designation
• Physical form factor: Surface mount TO-252-5 package (DPAK with 4 leads plus tab)

The BTS452TATMA1 meets all these criteria as a parametric equivalent, with the primary distinction being product status transition from obsolete to active availability.

Parameter Comparison

Engineering Selection Recommendations

The BTS452TATMA1 is the direct parametric equivalent for the obsolete BTS452TXT. Both components share identical electrical specifications, thermal ratings, and automotive-grade AEC-Q100 qualification. The transition from BTS452TXT to BTS452TATMA1 represents a product line update within the miniPROFET® series, maintaining full functional compatibility while providing active market availability.

The BTS452TATMA1 offers improved moisture sensitivity characteristics (MSL 1 versus MSL 3) and ROHS3 compliance, providing enhanced environmental robustness for long-term storage and handling. These improvements do not alter the core electrical or thermal performance required for direct substitution in existing designs.

Frequently Asked Questions (FAQ)

Q: Can BTS452TATMA1 be used as a direct replacement for BTS452TXT in existing designs?

A: Yes. The BTS452TATMA1 is a parametric equivalent with identical electrical specifications, output current rating (1.8A), on-resistance (150mOhm), load voltage range (6V–52V), thermal operating range (-40°C to 150°C), and package form factor (TO-252-5). Both components maintain the same 1:1 input-output ratio, high-side N-Channel configuration, and automotive AEC-Q100 qualification.

Q: What is the primary difference between BTS452TXT and BTS452TATMA1?

A: The BTS452TXT is classified as obsolete, while BTS452TATMA1 is an active product. The BTS452TATMA1 features improved moisture sensitivity level (MSL 1 with unlimited shelf life versus MSL 3 with 168-hour limitation) and ROHS3 compliance. Electrical and thermal performance remain identical.

Q: Are the pin configurations identical between these parts?

A: Yes. Both components use the TO-252-5 package (DPAK with 4 leads plus tab), ensuring identical PCB footprint and pin assignment compatibility.

Q: What certifications apply to both parts?

A: Both BTS452TXT and BTS452TATMA1 carry automotive-grade designation with AEC-Q100 qualification, suitable for automotive and industrial applications requiring high-reliability power switching.

Q: Is there any difference in fault protection between the two parts?

A: No. Both components provide identical fault protection: current limiting (fixed), over-temperature protection, and over-voltage protection with auto-restart capability.
