Infineon Technologies TLE7183QUXUMA8

Overview

TLE7183QUXUMA8 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 (SCD1–SCD5). It drives external N-channel MOSFETs in cooling fans, water pumps, and electric power steering systems.

For engineers reviewing the TLE7183QUXUMA8 datasheet, TLE7183QUXUMA8 pinout, TLE7183QUXUMA8 application, or TLE7183QUXUMA8 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 AEC-Q100 qualification for under-hood deployment.

Technical Context

The TLE7183QUXUMA8 integrates three floating high-side drivers with level shifters and three low-side drivers, each with dedicated input (IHx/ILx) and output (GHx/GLx) pins. It employs two independent charge pump circuits (CH1/CL1/CB1 and CH2/CL2/CB2) to sustain high-side gate drive above VS during extended duty cycles.

Protection architecture includes per-phase short-circuit detection referenced to VDH, programmable dead time (DT pin), shoot-through prevention logic, undervoltage/overvoltage shutdown, overtemperature warning, and 2-bit error coding on ERR1/ERR2 outputs. Phase voltage feedback (U_fb/V_fb/W_fb) provides digital logic-level representations of motor phase voltages.

FAQ

What is the purpose of the VDH pin?

The VDH pin connects to the drain nodes of all three high-side MOSFETs and serves as the reference point for short-circuit detection. Internal comparators monitor voltage drop across the high-side MOSFETs relative to VDH to identify phase-to-ground faults. Its voltage rating varies with INH state (up to 55 V when INH=high), enabling robust fault detection even during transients.

How does the TLE7183QUXUMA8 support low-voltage operation?

The device operates down to 5.5 V supply voltage using two integrated charge pumps that generate boosted gate drive voltages for high-side MOSFETs. This eliminates reliance on external bootstrap capacitors or auxiliary supplies, ensuring reliable commutation during automotive cold-crank conditions without performance degradation or loss of gate drive strength.

Can the TLE7183QUXUMA8 drive both N-channel and P-channel high-side MOSFETs?

No - the TLE7183QUXUMA8 is designed exclusively for N-channel high-side MOSFETs. Its floating high-side drivers use level-shifted logic and charge pumps to provide gate-to-source voltage >10 V, which is required for full enhancement of standard automotive N-channel devices. P-channel MOSFETs are not supported due to incompatible drive polarity and lack of integrated pull-up structures.

What diagnostic information is encoded on ERR1 and ERR2?

ERR1 and ERR2 form a 2-bit error code indicating fault type: short circuit (0b01), overtemperature warning (0b10), undervoltage shutdown (0b11), overvoltage shutdown (0b00), and overcurrent warning (0b10 with different timing context). The encoding is defined in the datasheet's diagnostic logic section and requires external decoding logic or MCU GPIO interpretation.
