Product details
Overview
TLE7183QUXUMA7 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 TLE7183QUXUMA7 datasheet, TLE7183QUXUMA7 pinout, TLE7183QUXUMA7 application, or TLE7183QUXUMA7 equivalent, key selection criteria include gate drive strength (400 nC load, ~150 ns rise/fall), SCD threshold programmability, dead-time control via DT pin, and AEC-Q100 qualification for under-hood environments.
Technical Context
The TLE7183QUXUMA7 integrates dual floating high-side drivers with level shifters and bootstrap/charge-pump support for sustained high-side conduction at VS ≥ 5.5 V. Each channel includes shoot-through protection with programmable dead time and independent short-circuit detection using VDH sensing with five factory-set thresholds (0.5 V to 2.0 V).
It embeds analog signal conditioning for shunt-based current sensing (VO output, ISP/ISN inputs) and phase voltage feedback (U_fb/V_fb/W_fb digital logic outputs), plus thermal, overvoltage, and undervoltage monitoring with two ERRx diagnostic pins encoding 2-bit fault status.
Key Specifications

| Package | PG-TQFP-48 with exposed heat slug - provides thermal path for >3 W dissipation in compact layouts |
Pinout & Package
Package: PG-TQFP-48 (7 mm × 7 mm, 0.5 mm pitch) with thermally enhanced exposed pad (VPD = GND-connected slug).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

| DT | Dead time adjustment | Analog pin setting minimum off-time between complementary HS/LS transitions to prevent shoot-through |
| VTHOC | Overcurrent threshold | External resistor sets current-sense amplifier trip point for overcurrent warning function |
Key Features
| Feature | Design Value |
|---|---|
| Integrated charge pumps | Two independent charge-pump circuits (CH1/CL1, CH2/CL2) sustain high-side gate drive at VS < 12 V without external bootstrap diodes |
| Shunt current sensing | On-chip op-amp (ISP/ISN → VO) with AGND-referenced output enables precise low-side current measurement |
| Phase voltage feedback | Digital U_fb/V_fb/W_fb outputs provide real-time phase state (high/low) for closed-loop commutation without ADC |
| Sleep mode | Low-quiescent-current state (< 100 µA) activated via ENA1/ENA2 deactivation - reduces standby power in parked vehicles |
| EMC-optimized layout | Dedicated GND pins (12 total), separated AGND/DGND, and symmetric driver paths minimize radiated emissions in noisy automotive environments |

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 |
|---|---|---|---|
| STGD3HF60S | Single high-side driver only; no integrated low-side or charge pumps; requires external bootstrap circuitry | Limited to single-phase or discrete half-bridge designs; lacks SCD, diagnostics, and phase feedback | Select only for cost-sensitive non-automotive 3-phase systems where full integration is unnecessary |
| DRV8305-Q1 | Integrated 3-phase gate driver + current sense amplifiers + buck regulator; SPI interface; no VDH-based SCD | Supports advanced closed-loop control via SPI register access but uses different fault reporting (SPI flags vs. ERRx pins) | Prefer when system requires programmable protection thresholds and integrated DC/DC, not fixed-threshold SCD |
Compared with STGD3HF60S and DRV8305-Q1, the TLE7183QUXUMA7 delivers deterministic, hardware-based short-circuit response (2 µs detection), AEC-Q100 Grade 0 operation, and minimal external components - making it optimal for safety-critical, high-reliability automotive inverters where firmware-independent protection is mandatory.

FAQ
What is the purpose of the VDH pin on the TLE7183QUXUMA7?
The VDH pin connects to the drain nodes of all three high-side MOSFETs and serves as the sensing input for hardware-based short-circuit detection. Internal comparators monitor voltage drop across the MOSFETs' RDS(on) during conduction; five factory-set thresholds (0.5 V to 2.0 V) determine trip points, enabling rapid fault detection without software intervention.
Does the TLE7183QUXUMA7 require external bootstrap capacitors?
No - the device integrates two independent charge-pump circuits (CH1/CL1 and CH2/CL2) that generate boosted gate-drive voltages for high-side MOSFETs, eliminating the need for external bootstrap diodes or capacitors. This ensures reliable high-side drive even during extended low-VS conditions (down to 5.5 V) typical of automotive cold-crank events.
How does the TLE7183QUXUMA7 implement dead-time control?
Dead time is set via an external resistor connected to the DT pin, which adjusts the minimum off-time between complementary high-side and low-side gate drive signals. This analog-programmable feature prevents shoot-through by ensuring both switches in a half-bridge are never simultaneously on, with typical values ranging from 200 ns to 2 µs depending on resistor value and temperature.
Can the TLE7183QUXUMA7 be used with N-channel-only MOSFET topologies?
Yes - the IC is explicitly designed for N-channel high-side and low-side MOSFET configurations. Its integrated charge pumps provide the required gate-source voltage (>10 V) for high-side N-MOSFETs, and its TTL-compatible inputs (IHx active-low, ILx active-high) simplify interface with standard microcontrollers or gate driver logic in 3-phase inverter stages.
