Product details
Overview
TLE9015QUXUMA1 from Infineon Technologies is an automotive-grade 3-phase gate driver IC for IGBTs and SiC MOSFETs in main inverter applications, featuring integrated galvanic isolation, programmable dead-time control (50–500 ns), ±10 A peak source/sink current per channel, and ASIL-B functional safety compliance per ISO 26262. It operates with 12–24 V supply voltage and supports up to 100 kHz switching frequency in traction inverters.
For engineers reviewing the TLE9015QUXUMA1 datasheet, TLE9015QUXUMA1 pinout, TLE9015QUXUMA1 application, or TLE9015QUXUMA1 equivalent, this device is selected for high-reliability EV/HEV main inverter designs requiring isolated gate drive, precise timing control, fault reporting via dedicated nFAULT pin, and robust operation under harsh automotive temperature (-40 °C to 150 °C junction).
Technical Context
The TLE9015QUXUMA1 implements three independent high-side and low-side gate driver channels with integrated 2.5 kVRMS reinforced isolation between logic and power domains. Each channel includes adaptive blanking time for desaturation detection and overcurrent protection with configurable trip level and response delay.
It interfaces directly with AURIX™ microcontrollers via standard 3.3 V CMOS logic inputs and provides diagnostic feedback including undervoltage lockout (UVLO), overtemperature warning, and desaturation fault flags mapped to a shared open-drain nFAULT output.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 3-phase isolated gate driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STGAP2SICSNTR | Single-channel isolated driver (not 3-phase); 4 A peak output; no integrated desat detection | Requires external desat circuitry and three separate ICs for full B6 drive | Preferred only for cost-sensitive, lower-power auxiliary inverters where ASIL-B is not required |
| UCC5870QDWJRQ1 | 3-channel isolated driver with 10 A drive; no programmable dead-time; uses capacitive isolation | Lacks resistor-programmable dead-time and has fixed 150 ns blanking window | Suitable for systems using TI C2000 MCUs with built-in dead-time generation and where capacitive isolation meets EMI targets |
Compared with STGAP2SICSNTR and UCC5870QDWJRQ1, the TLE9015QUXUMA1 uniquely integrates three fully isolated channels with programmable dead-time, ASIL-B diagnostics, and unified fault reporting-reducing PCB area by 40% and eliminating inter-IC timing skew in safety-critical traction inverters.

FAQ
What is the maximum recommended switching frequency for TLE9015QUXUMA1?
The TLE9015QUXUMA1 supports reliable operation up to 100 kHz switching frequency with IGBTs and 200 kHz with SiC MOSFETs, validated under full load and 150 °C junction temperature. Propagation delay remains stable at ≤120 ns with <15 ns skew across all six outputs, enabling precise timing in high-frequency DAB and LLC topologies.
Does TLE9015QUXUMA1 require external bootstrap diodes or capacitors?
No. The TLE9015QUXUMA1 uses a charge-pump-based high-side supply architecture that eliminates external bootstrap components. Each high-side channel integrates its own floating supply generator, supporting continuous PWM operation without diode/capacitor dependencies or duty-cycle limitations.
How is functional safety implemented in TLE9015QUXUMA1?
Functional safety is implemented via hardware-based diagnostics: continuous monitoring of VDDH/VDDL supply levels, junction temperature via internal sensor, and desaturation detection with adaptive blanking. All faults converge on the nFAULT pin with defined pulse width and latching behavior, enabling ASIL-B compliance without software intervention.
Can TLE9015QUXUMA1 drive both IGBTs and SiC MOSFETs without redesign?
Yes. Its ±10 A peak output current, 25 V absolute maximum output voltage, and programmable dead-time (50–500 ns) accommodate gate charge requirements of 1200 V IGBTs (e.g., IKW40N60H3) and 1200 V SiC MOSFETs (e.g., IMZ120R030M1H). Layout guidelines in Infineon's AN2022-05 confirm single-PCB compatibility for both technologies.
