Product details
Overview
TLE7183FXUMA6 from Infineon Technologies is a 3-phase high- and low-side MOSFET gate driver IC for automotive motor control, featuring six independent gate outputs (3 high-side, 3 low-side), integrated charge pumps enabling operation down to 5.5 V supply, 150 ns typical rise/fall times, and five selectable fixed short-circuit detection thresholds. It drives external N-channel MOSFETs in cooling fans, electric power steering, and water pumps.
For engineers reviewing the TLE7183FXUMA6 datasheet, TLE7183FXUMA6 pinout, TLE7183FXUMA6 application, or TLE7183FXUMA6 equivalent, key selection criteria include gate drive strength at low battery voltage, shoot-through protection timing, shunt-based current sensing accuracy, and AEC-Q100 qualification for under-hood deployment.
Technical Context
The TLE7183FXUMA6 integrates dual floating high-side drivers with integrated charge pumps (CH1/CL1 and CH2/CL2) to sustain gate voltage above VS during high-side conduction, supporting operation from 5.5 V to 45 V supply. Each of the three half-bridge channels includes independent INH-controlled enable logic, programmable dead time (via DT pin), and separate high- and low-side input polarity (IHx active-low, ILx active-high).
It embeds real-time protection circuitry including overcurrent warning (via VTHOC threshold setting), undervoltage/overvoltage shutdown, thermal overload warning, and phase-voltage feedback (U_fb/V_fb/W_fb) for commutation timing. The integrated current sense amplifier (ISP/ISN → VO) provides bidirectional shunt monitoring with analog output referenced to AGND.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar 3-phase gate driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DRV3205-Q1 | Single-supply design (no charge pumps); requires external bootstrap or isolated supply for high-side drive | Limited to higher VS (>9 V); less suitable for cold-crank operation | Select when system supply remains >9 V and board space permits external bootstrap components |
| MC33883 | Legacy 3-phase driver with lower drive strength (±0.6 A), no integrated shunt amplifier, and no phase feedback inputs | Requires external op-amps for current sensing and external logic for commutation timing | Select only for cost-sensitive legacy designs where diagnostic depth and integration are secondary |

FAQ
What is the purpose of the VTHOC pin?
The VTHOC pin sets the overcurrent detection threshold for the integrated short-circuit protection. It accepts an analog voltage (0.2 V to 1.2 V) that maps directly to one of five fixed trip levels defined by the SCD variant (SCD1–SCD5). This allows precise tuning of fault sensitivity without firmware changes.
Does TLE7183FXUMA6 support sensorless commutation?
Yes - it provides three dedicated digital inputs (U_fb, V_fb, W_fb) that decode motor phase voltages into logic-level signals. These feed directly into microcontroller GPIOs or timers to implement sensorless field-oriented control (FOC) or six-step commutation without Hall sensors or encoders.
How does the charge pump architecture enable low-voltage operation?
The dual integrated charge pumps (CH1/CL1 and CH2/CL2) generate boosted gate drive voltage (~VS + 10 V) for high-side MOSFETs, maintaining sufficient VGS even when VS drops to 5.5 V. This eliminates need for external bootstrap diodes/capacitors and ensures reliable high-side turn-on during cold-crank conditions.
Can TLE7183FXUMA6 drive both N-channel and P-channel high-side MOSFETs?
No - it is optimized exclusively for N-channel high-side MOSFETs using floating driver architecture and charge pumps. P-channel high-side use is not supported; the gate drive logic, voltage ranges, and protection features assume N-channel configuration with source-connected switching nodes.
