Product details
Overview
TLE7183QUXUMA3 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 for 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 TLE7183QUXUMA3 datasheet, TLE7183QUXUMA3 pinout, TLE7183QUXUMA3 application, or TLE7183QUXUMA3 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 TLE7183QUXUMA3 implements three floating high-side drivers with level-shifted control and integrated charge pumps (CH1/CL1/CB1 and CH2/CL2/CB2) enabling operation at VS ≥ 5.5 V. Each high-side output (GH1–GH3) supports up to 55 V drain voltage, while low-side outputs (GL1–GL3) tolerate −7 V to +18 V.
It integrates real-time protection: five selectable short-circuit detection thresholds (0.5–2.0 V at VTHOC), shoot-through prevention via programmable dead time (DT pin), overtemperature warning, undervoltage/overvoltage shutdown, and 2-bit error diagnosis via ERR1/ERR2 pins for fault classification.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 5.5 V to 45 V - enables full functionality across cold-crank (5.5 V) to load-dump (45 V) automotive transients |
| Gate Drive Capability | Drives 400 nC MOSFETs with ~150 ns rise/fall - ensures fast switching and reduced conduction losses in high-current 3-phase inverters |

| Short-Circuit Detection | 5 fixed thresholds (0.5 V to 2.0 V) - configurable via VTHOC pin for precise current-limiting in varied motor winding resistances |
| Phase Feedback Inputs | U_fb, V_fb, W_fb - digital logic-level representations of phase voltages for commutation timing and fault monitoring |
| Current Sense Interface | ISP/ISN differential inputs + VO opamp output - enables high-side or low-side shunt-based current measurement with rail-to-rail output swing |

| ENA1 / ENA2 | Enable inputs | Active-high dual enables allowing independent activation of driver sections or system-level safety redundancy |
Key Features
| Feature | Design Value |
|---|---|
| Integrated charge pumps | Two independent charge pump circuits (CH1/CL1/CB1 and CH2/CL2/CB2) sustain high-side drive at VS ≥ 5.5 V without external bootstrap components |
| Programmable dead time | Adjustable minimum off-time via DT pin voltage - prevents cross-conduction in half-bridge legs during PWM transitions |
| 5-level short-circuit detection | Selectable thresholds (0.5 V, 0.75 V, 1.0 V, 1.5 V, 2.0 V) via VTHOC pin - enables tuning to motor phase resistance and cable impedance |
| 2-bit diagnostic encoding | ERR1/ERR2 pins output binary-coded fault type (e.g., 01 = overtemperature, 10 = short circuit) - simplifies microcontroller fault interpretation |
| Shunt amplifier with bias reference | VRI/VRO provide stable 2.5 V reference; ISP/ISN/VO form calibrated current-sense path with ±1% gain accuracy over temperature |

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 |
|---|---|---|---|
| BD9M300MUV | Single-supply 3-phase driver (no charge pumps); max VS = 28 V; no shunt amplifier; only 1-bit fault flag | Limited to low-voltage EV auxiliary systems (e.g., HVAC blowers); lacks AEC-Q100 Grade 0 rating | Choose when cost sensitivity outweighs under-hood robustness and diagnostic depth |
| MP6532 | 60 V max VS; integrated current sense ADC; no phase feedback outputs; SPI configuration interface | Suitable for industrial BLDC drives; requires external MCU for commutation logic and fault interpretation | Prefer when digital configurability and higher voltage margin are prioritized over analog phase feedback and automotive qualification |

FAQ
What is the purpose of the VTHOC pin on the TLE7183QUXUMA3?
The VTHOC pin sets the threshold voltage for overcurrent and short-circuit detection. It accepts five discrete voltage levels (0.5 V, 0.75 V, 1.0 V, 1.5 V, 2.0 V) corresponding to SCD1–SCD5 options, enabling precise current-limit tuning based on motor phase resistance and shunt value without firmware changes.
How does the TLE7183QUXUMA3 support operation below 12 V supply?
It uses two integrated charge pump circuits (CH1/CL1/CB1 and CH2/CL2/CB2) to generate boosted gate drive voltages, sustaining full high-side drive capability down to VS = 5.5 V - essential for cold-crank conditions in 12 V automotive networks without external bootstrap diodes or capacitors.
Can the TLE7183QUXUMA3 drive both N-channel and P-channel high-side MOSFETs?
No - the TLE7183QUXUMA3 is designed exclusively for N-channel high-side MOSFETs, using floating channel drivers with integrated charge pumps. Its GHx outputs require referenced source connections (SHx pins) and cannot interface with P-channel devices, which lack compatible level-shifting architecture.
What diagnostic information is encoded on ERR1 and ERR2?
ERR1 and ERR2 form a 2-bit code indicating fault type: 00 = no fault, 01 = overtemperature warning, 10 = short circuit or overcurrent, 11 = undervoltage or overvoltage shutdown. This allows microcontrollers to distinguish critical failure modes without additional analog monitoring circuitry.
