Infineon Technologies TLE7183QUXUMA2

Overview

TLE7183QUXUMA2 from Infineon is a 3-phase high- and low-side MOSFET driver IC for automotive motor control, featuring six independent gate drivers (3 high-side + 3 low-side), integrated charge pumps enabling operation down to 5.5 V supply, 30 kHz PWM capability, and fixed short-circuit detection levels (SCD2/SCD5 variants). It drives external N-channel MOSFETs in cooling fans, electric power steering, and water pumps.

For engineers reviewing the TLE7183QUXUMA2 datasheet, TLE7183QUXUMA2 pinout, TLE7183QUXUMA2 application, or TLE7183QUXUMA2 equivalent, key selection criteria include gate drive strength (400 nC load, ~150 ns rise/fall), dual enable inputs (ENA1/ENA2), phase voltage feedback (U_fb/V_fb/W_fb), shunt current sensing (ISP/ISN/VO), and diagnostic error signaling (ERR1/ERR2) with 2-bit encoding.

Technical Context

The TLE7183QUXUMA2 implements three independent floating high-side drivers with integrated level shifters and bootstrap/charge-pump biasing (CL1/CH1/CB1 and CL2/CH2/CB2), supporting operation at VS ≥ 5.5 V. Each high-side output (GH1–GH3) and low-side output (GL1–GL3) is separately controllable via TTL-compatible inputs (IHx/ILx) with active-low high-side and active-high low-side logic polarity.

It integrates real-time protection including shoot-through prevention via programmable dead time (DT pin), undervoltage/overvoltage shutdown, overtemperature warning, and five selectable short-circuit detection thresholds (SCD1–SCD5); SCD2 (0.75 V) and SCD5 (2.0 V) are production-available options. Diagnostic status is reported through ERR1/ERR2 pins with 2-bit encoded fault codes.

FAQ

What is the function of the DT pin on the TLE7183QUXUMA2?

The DT (Dead Time) pin sets the minimum off-time between complementary high-side and low-side MOSFET switching using an external resistor-to-ground. This analog-adjustable dead time prevents shoot-through current by ensuring both switches are never simultaneously conducting, with typical values ranging from 100 ns to 1 µs depending on resistor value and temperature.

Does the TLE7183QUXUMA2 require external bootstrap capacitors?

No - the TLE7183QUXUMA2 integrates two independent charge pump circuits (using CH1/CL1/CB1 and CH2/CL2/CB2) that generate boosted gate drive voltage for high-side MOSFETs, eliminating the need for external bootstrap diodes or capacitors and enabling reliable operation even at VS = 5.5 V during cold-crank conditions.

How does the SCD option (e.g., SCD2) affect system design?

The SCD option defines the fixed voltage threshold at which short-circuit detection triggers: SCD2 = 0.75 V across the shunt resistor. This determines the minimum detectable fault current (e.g., 75 A at 10 mΩ shunt) and must be matched to motor phase resistance, wiring inductance, and expected fault energy to avoid nuisance tripping while ensuring timely shutdown.

Can the TLE7183QUXUMA2 operate without connecting all GND pins?

No - all 7 GND pins (pins 2, 20, 32, 37, 47, and two implied in package thermal slug) must be connected to a low-impedance ground plane. Separating logic and power grounds or omitting any GND connection risks noise coupling into sensitive analog blocks (shunt amplifier, reference buffer) and may cause erratic behavior or thermal shutdown due to elevated junction temperature.
