TLE8104EXUMA2 Equivalent & Substitute Parts

Part Overview

The TLE8104EXUMA2 is a Power Management Integrated Circuit (PMIC) functioning as a power switch/driver with 1:1 N-Channel configuration and 1A maximum output current. Manufactured by Infineon Technologies, this component is classified as obsolete, necessitating identification of active equivalent parts for new designs and ongoing production requirements. The part operates across a load voltage range of 4.5V to 5.5V with automotive-grade qualification and comprehensive fault protection including open load detection, over-temperature, and over-voltage monitoring.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TLE8104EXUMA2 is determined by the following critical parameters:

• Output Configuration & Type: Both main and substitute parts must maintain Low Side, N-Channel output topology with 4 outputs
• Interface Protocol: SPI interface compatibility is mandatory
• Package Compatibility: Physical form factor must accommodate the 20-pin SOIC/BFSOP package footprint (0.295", 7.50mm width)
• Fault Protection Features: Open Load Detect capability is required; additional protection features in substitutes are acceptable enhancements
• Operating Temperature Range: Minimum -40°C to 150°C specification must be met
• Compliance Standards: RoHS3 compliance and automotive-grade qualification are baseline requirements

The TLE9104SHXUMA1 qualifies as a manufacturer-recommended substitute based on these parameters. While the substitute exhibits enhanced electrical performance (3A vs. 1A output current, 150mOhm vs. 320mOhm Rds On) and expanded voltage capability (50V ~ 60V load voltage), it maintains functional equivalence through identical output configuration, interface protocol, package family, and fault protection architecture.

Engineering Selection Recommendations

The TLE9104SHXUMA1 is the manufacturer-recommended substitute for the obsolete TLE8104EXUMA2. Selection of this substitute is supported by:

• Product Status Alignment: The substitute maintains active production status, ensuring long-term availability and supply chain continuity
• Compliance Certification: Both parts maintain identical RoHS3 compliance and automotive-grade qualification, satisfying regulatory and quality requirements
• Functional Equivalence: Identical output configuration (4-output Low Side N-Channel), interface protocol (SPI), and core fault protection features (Open Load Detect, Over Temperature) ensure functional compatibility
• Enhanced Performance Margin: The substitute provides superior electrical performance (3A vs. 1A output current, 150mOhm vs. 320mOhm Rds On) and expanded fault protection (Reverse Battery, Short Circuit, Current Limiting), offering design robustness without functional compromise
• Package Family Compatibility: Both parts utilize 20-pin packages with identical pitch and exposed pad configuration, supporting direct PCB layout compatibility with minimal redesign

Frequently Asked Questions (FAQ)

Q: Can the TLE9104SHXUMA1 directly replace the TLE8104EXUMA2 on existing PCBs?

A: The TLE9104SHXUMA1 is compatible with existing TLE8104EXUMA2 PCB layouts. Both parts use 20-pin packages with 0.295" (7.50mm) width and exposed pad configuration. However, verify that the specific package variant (SOIC vs. BFSOP) matches your PCB footprint definition, as minor dimensional variations may exist between package families.

Q: What are the key differences in electrical performance between these parts?

A: The TLE9104SHXUMA1 provides enhanced output current capability (3A vs. 1A) and lower on-resistance (150mOhm vs. 320mOhm). These improvements reduce power dissipation and enable higher load current applications. The substitute also expands load voltage range (50V ~ 60V vs. 4.5V ~ 5.5V) and adds Reverse Battery and Short Circuit protection features.

Q: Are both parts automotive-qualified?

A: Yes. Both the TLE8104EXUMA2 and TLE9104SHXUMA1 carry automotive-grade qualification and maintain ROHS3 compliance with identical Moisture Sensitivity Level (MSL 3, 168 Hours).

Q: Does the substitute maintain SPI interface compatibility?

A: Yes. Both parts implement SPI interface protocol with identical 4-output Low Side N-Channel configuration, ensuring software and firmware compatibility without modification.

Q: What is the supply voltage range for the TLE9104SHXUMA1?

A: The TLE9104SHXUMA1 operates with supply voltage (Vcc/Vdd) range of 3V ~ 5.5V, providing broader supply flexibility compared to the original part specification.
