Infineon Technologies TLE7183QUXUMA9

Overview

TLE7183QUXUMA9 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 TLE7183QUXUMA9 datasheet, TLE7183QUXUMA9 pinout, TLE7183QUXUMA9 application, or TLE7183QUXUMA9 equivalent, key selection criteria include gate drive strength (400 nC load, ~150 ns rise/fall), short-circuit detection threshold programmability, dead-time control via DT pin, and AEC-Q100 qualification for under-hood deployment.

Technical Context

The TLE7183QUXUMA9 integrates dual charge pumps (CH1/CL1 and CH2/CL2) to sustain high-side gate drive above VS during low-battery conditions (down to 5.5 V), with level-shifted floating drivers for each half-bridge. Its diagnostic logic monitors overtemperature, overvoltage, undervoltage, shoot-through, and short-circuit events using dedicated ERR1/ERR2 pins with 2-bit encoding.

Phase voltage feedback (U_fb/V_fb/W_fb) provides digital logic-level representations of motor phase voltages for commutation control, while shunt signal conditioning (ISP/ISN/VO) delivers amplified current-sense output with user-configurable gain via VTHOC and AGND-referenced biasing (VRI/VRO).

FAQ

What is the purpose of the DT pin on the TLE7183QUXUMA9?

The DT (Dead Time) pin sets the minimum off-time between complementary high-side and low-side gate drive signals using an external resistor-to-ground. This prevents shoot-through current by ensuring both switches in a half-bridge are never simultaneously on, with typical dead time ranging from 200 ns to 2 µs depending on resistor value. The pin accepts analog voltage input and is internally referenced to ensure consistent timing across temperature and supply variations.

How does the TLE7183QUXUMA9 handle low-battery conditions below 9 V?

The TLE7183QUXUMA9 uses two integrated charge pumps (CH1/CL1 and CH2/CL2) to generate boosted gate-drive voltages for high-side MOSFETs, enabling full functionality down to 5.5 V supply. Each pump supports one high-side driver pair, maintaining sufficient V_GS to keep MOSFETs fully enhanced during cold-cranking. The charge pumps automatically engage when VS drops below internal threshold and remain active until normal operation resumes.

Can the TLE7183QUXUMA9 be used without external shunt resistors?

No - the TLE7183QUXUMA9 requires an external shunt resistor between ISP and ISN to enable current sensing. The device contains only the differential amplifier (with programmable gain via VTHOC) and bias reference (VRI/VRO), but no integrated shunt. Typical placement is in the low-side leg of each phase, with AGND isolated from power ground to preserve measurement accuracy and noise immunity.

What does the marking "SCD2" indicate on the TLE7183QUXUMA9 top-side label?

The "SCD2" marking denotes the Short-Circuit Detection threshold option set to 0.75 V, one of five factory-programmed levels (SCD1 = 0.5 V, SCD2 = 0.75 V, SCD3 = 1.0 V, SCD4 = 1.5 V, SCD5 = 2.0 V). This value defines the voltage threshold at which the device triggers short-circuit protection on the VDH pin, calibrated to detect MOSFET drain-source shorts based on system-specific R_DS(on) and layout resistance.
