Product details
Overview
TLE7183QUXUMA1 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 available). It drives external N-channel MOSFETs in cooling fans, electric power steering, and water pumps.
For engineers reviewing the TLE7183QUXUMA1 datasheet, TLE7183QUXUMA1 pinout, TLE7183QUXUMA1 application, or TLE7183QUXUMA1 equivalent, key selection criteria include gate drive strength (400 nC load, ~150 ns rise/fall), dual enable inputs (ENA1/ENA2), dead-time programmability (DT pin), shunt-based current sensing (ISP/ISN/VO), and phase voltage feedback (U_fb/V_fb/W_fb) for closed-loop 3-phase BLDC control.
Technical Context
The TLE7183QUXUMA1 integrates three floating high-side drivers with level-shifted logic and three ground-referenced low-side drivers, each with dedicated input pins (IHx/ILx) and gate outputs (GHx/GLx). It employs two independent charge pump circuits (CH1/CL1/CB1 and CH2/CL2/CB2) to sustain high-side gate voltage above VS during 100% duty cycle operation.
Protection architecture includes per-phase short-circuit detection referenced to VDH, overcurrent warning via internal current sense amplifier (ISP/ISN → VO), undervoltage/overvoltage shutdown, thermal overload warning, and hardware-enforced shoot-through prevention via programmable dead time (DT pin) and synchronous inhibit (INH).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 5.5 V to 45 V - supports full functionality across cold-crank (5.5 V) to load-dump (45 V) automotive transients. |

| Package | PG-TQFP-48 with exposed heat slug - provides low thermal resistance for high-power motor drive applications in constrained automotive environments. |
Pinout & Package
Package: PG-TQFP-48 (7 mm × 7 mm, 0.5 mm pitch) with thermally enhanced exposed pad for improved heat dissipation in automotive motor drive modules.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| SH1–SH3 | High-side source connection | Reference node for high-side floating driver stage; ties to drain of external high-side MOSFETs for short-circuit detection via VDH. |
| SL1–SL3 | Low-side source connection | Ground reference for low-side gate drivers; connects to source of external low-side MOSFETs and system power ground. |
| GH1–GH3 / GL1–GL3 | Gate drive outputs | Direct high-current outputs driving MOSFET gates; GHx rated for -7 V to +55 V, GLx for -7 V to +18 V, supporting robust switching. |
| IH1–IH3 / IL1–IL3 | Control inputs | IHx: active-low high-side enable; ILx: active-high low-side enable - allows independent, asynchronous control of all six switches. |
| ENA1 / ENA2 | Global enable inputs | Active-high dual enable pins - required high for operation; used for system-level safety interlock and functional redundancy. |
| DT | Dead-time programming | Analog pin setting minimum off-time between complementary high/low-side switch transitions - prevents shoot-through in bridge legs. |
| ISP / ISN / VO | Shunt signal conditioning | Differential current sense inputs (ISP+, ISN−) and buffered output (VO) - enables accurate, noise-immune motor phase current measurement. |
| U_fb / V_fb / W_fb | Phase voltage feedback | Logic-level inputs translating motor back-EMF zero-crossings into timing signals - essential for sensorless BLDC commutation algorithms. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated dual charge pumps | Enables reliable high-side gate drive at VS as low as 5.5 V without external bootstrap components - critical for cold-crank operation. |
| Programmable dead time | Hardware-configurable minimum off-time via DT pin - eliminates need for MCU-based dead-time insertion and reduces software complexity. |
| 2-bit error diagnosis | ERR1/ERR2 outputs encode five fault types (short circuit, overtemp, UV/OV, overcurrent) - simplifies diagnostic communication with host controller. |
| Separate source connections per switch | Independent SLx/SHx pins per phase - allows Kelvin sensing and minimizes layout-induced shoot-through risk in high-current PCB traces. |
| AEC-Q100 qualified | Qualified for automotive Grade 0 (-40 °C to +150 °C junction) - meets reliability and stress-test requirements for safety-critical powertrain and chassis systems. |

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 |
|---|---|---|---|
| DRV8305-Q1 | Integrated MOSFETs (6x 40 V, 3.5 A), no external shunt interface; uses SPI for configuration instead of analog DT/VDH. | Targeted at lower-current (<10 A) space-constrained modules; lacks discrete shunt amplifier and phase feedback inputs. | Select when board area is critical and integrated FETs suffice; avoid if external high-current MOSFETs or sensorless commutation via U_fb/V_fb/W_fb are required. |
| MC33883 | Single high-side + dual low-side topology; no charge pumps; max VS = 28 V; no phase feedback inputs. | Designed for 2-phase or single-phase brushed DC motors; not suitable for 3-phase BLDC with sensorless control. | Select only for simpler brushed motor applications; reject for any 3-phase inverter requiring high-side floating drive or U_fb/V_fb/W_fb timing signals. |
Compared with DRV8305-Q1 and MC33883, the TLE7183QUXUMA1 uniquely combines external MOSFET flexibility, analog programmability (DT, VTHOC), dedicated phase feedback inputs, and AEC-Q100 Grade 0 qualification - making it the only option among the three capable of full-featured, high-power automotive 3-phase BLDC control with sensorless commutation and comprehensive diagnostics.

FAQ
What is the purpose of the VDH pin?
The VDH pin serves as the common sense node for short-circuit detection across all three high-side switches. It connects to the drains of the external high-side MOSFETs and compares voltage against internally set thresholds (e.g., 0.75 V for SCD2) to detect phase-to-ground faults. Its voltage rating changes based on INH state, allowing safe operation during both active and inhibited modes.
Can TLE7183QUXUMA1 operate without external charge pump capacitors?
No. The TLE7183QUXUMA1 requires two external charge pump capacitor networks: CH1/CL1/CB1 for high-side driver 1 and CH2/CL2/CB2 for drivers 2 and 3. Omitting these capacitors disables high-side gate drive functionality, resulting in incomplete 3-phase operation and potential shoot-through failure. Recommended values are 100 nF ceramic for CL1/CL2 and 220 nF for CB1/CB2.
How does the DT pin affect dead time?
The DT pin accepts an analog voltage (0.5 V to 2.5 V) that linearly sets the minimum dead time between complementary high-side and low-side gate transitions - ranging from ~200 ns at 0.5 V to ~1.2 µs at 2.5 V. This hardware-programmed value overrides any software-inserted dead time, ensuring deterministic shoot-through prevention independent of MCU timing jitter.
Is TLE7183QUXUMA1 compatible with 48 V mild-hybrid systems?
No. The absolute maximum VS rating is 45 V (continuous) and 47 V (transient), with functional operation specified only up to 28 V for certain VDH conditions. While it withstands brief 48 V transients, sustained operation above 28 V violates functional range limits and risks undervoltage lockout or incorrect protection triggering - use Infineon's newer TLE9183QX for true 48 V compatibility.
