Product details
Overview
TLE7184F3VXUMA1 from Infineon Technologies is an automotive-grade System IC for B6 (3-phase bridge) brushless DC motor drives, integrating six N-channel MOSFET gate drivers, a 3.3 V low-drop voltage regulator for microcontroller supply, analog current-sense amplifier, VDH high-side common-drain monitoring, and comprehensive protection including overtemperature, overvoltage, short-circuit, and shoot-through detection. It operates at up to 25 kHz PWM frequency with 0–94% duty cycle control and supports AEC-Q100 qualification.
For engineers reviewing the TLE7184F3VXUMA1 datasheet, TLE7184F3VXUMA1 pinout, TLE7184F3VXUMA1 application, or TLE7184F3VXUMA1 equivalent, key selection criteria include bootstrap-based high-side drive capability, adjustable dead time and short-circuit threshold, analog temperature output, ERR open-drain diagnostic flag, and PG-VQFN-48 package thermal performance in under-hood automotive environments.
Technical Context
The TLE7184F3VXUMA1 implements three independent floating high-side/low-side driver stages with integrated level shifters and shoot-through protection logic. Each phase includes dedicated IHx/ILx inputs, GHx/GLx gate outputs, BHx bootstrap supply pins, and SHx source sensing nodes - enabling full B6 topology control without external level-shifting circuitry.
It integrates a precision current-sense opamp (ISP/ISN/ISO) with gain and offset calibrated for shunt-based motor phase current measurement, plus analog TEMP output and digital ERR flag for real-time fault reporting. Protection functions are hierarchically prioritized: OTSD triggers immediate shutdown, while VDD_UVSD, VREG_UVSD, and OCSD operate with configurable thresholds and recovery behavior.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| PWM Frequency | Up to 25 kHz - supports standard BLDC commutation timing without aliasing in automotive ECU-controlled drives. |
| Duty Cycle Range | 0–94% - enables precise torque control while retaining margin for dead time insertion and transient headroom. |
| VREG Output | 3.3 V ±2%, 150 mA - powers automotive microcontrollers directly; eliminates need for external LDO in compact motor control modules. |
| Short-Circuit Threshold | Analog-adjustable via SCDL pin (0.2–1.2 V range) - allows fine-tuning of overcurrent trip point per application load profile. |
| Thermal Shutdown | 150 °C typical OTSD trigger - protects silicon during sustained overload or cooling failure; analog TEMP output enables predictive thermal management. |
| ERR Pin Type | Open-drain, active-low - simplifies wired-OR fault bus implementation across multi-driver systems with single MCU interrupt input. |
| VS Operating Range | 5.5–28 V - accommodates 12 V automotive battery transients including load dump (up to 40 V absolute max). |
Pinout & Package
Package: PG-VQFN-48 (7 mm × 7 mm, 0.5 mm pitch), thermally enhanced with exposed pad soldered to PCB ground plane for ≤40 °C/W junction-to-board thermal resistance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| GH1–GH3, GL1–GL3 | High-/low-side gate drive outputs | Direct connection to N-MOSFET gates; GHx outputs support bootstrap operation up to 60 V floating potential. |
| BH1–BH3 | Bootstrap capacitor positive terminals | Supply nodes for high-side level shifters; require ceramic capacitors (≥100 nF) placed adjacent to each BHx pin. |
| SH1–SH3 | High-side source sense nodes | Enable current reconstruction and shoot-through detection by monitoring high-side MOSFET source potential relative to GND. |
| IL1–IL3, IH1–IH3 | Phase control inputs | Active-high low-side / active-low high-side logic inputs compatible with 3.3 V or 5 V MCU GPIOs; internally debounced. |
| SCDL, DT, TEMP, ERR | Analog/digital configuration & monitoring | SCDL sets short-circuit threshold; DT adjusts dead time (100–500 ns); TEMP provides ratiometric 0.5–2.5 V temp signal; ERR flags latched faults. |
| VREG, VDD, VS, IOV, VDH | Power and sensing rails | VREG powers MCU core; VDD is internal 3.3 V rail; VS is main battery input; IOV monitors high-side drain voltage; VDH is common high-side drain node. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated 3.3 V µC supply | 150 mA regulated output with UVLO and shutdown - reduces BOM count and PCB area in space-constrained motor modules. |
| Adjustable dead time | Configurable via external resistor on DT pin (100–500 ns range) - prevents cross-conduction without firmware overhead. |
| Analog current sense amplifier | ISP/ISN differential inputs with rail-to-rail ISO output - enables accurate, low-noise shunt-based phase current measurement without external opamp. |
| Multi-level protection architecture | Independent OTSD, OCSD, OVSD, and SCP with priority-based shutdown - ensures fail-safe operation under combined fault conditions. |
| AEC-Q100 qualified | Grade 1 (−40 °C to +125 °C ambient) - validated for engine bay placement in electric power steering, HVAC blowers, and radiator fans. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 3-phase gate driver with integrated protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DRV3205-Q1 | Single-package dual 3-phase driver (6 half-bridges), no integrated VREG or analog TEMP output; requires external 3.3 V supply. | Lacks on-chip current sense amplifier and analog temperature monitoring; suited for designs with existing sensing infrastructure. | Select when higher channel density is required and external sensing is already implemented; verify external VREG meets 150 mA peak demand. |
| STSPIN32F0A | Embedded 32-bit ARM Cortex-M0 MCU + gate drivers + 3.3 V LDO; fixed 120 ns dead time; no adjustable SCDL or analog TEMP. | Offers integrated motor control firmware but less flexible analog diagnostics; limited to 20 kHz PWM and 12 V VS max. | Choose for rapid prototyping with field-oriented control (FOC) stack; avoid if >25 kHz operation or analog thermal profiling is needed. |
Compared with DRV3205-Q1 and STSPIN32F0A, TLE7184F3VXUMA1 uniquely combines adjustable dead time, analog short-circuit threshold tuning, and ratiometric temperature output in a standalone driver - making it optimal for cost-sensitive, thermally demanding automotive actuators where MCU resources are constrained.

FAQ
What is the maximum allowable VS supply voltage for continuous operation?
The TLE7184F3VXUMA1 supports continuous operation from 5.5 V to 28 V on the VS pin. Absolute maximum rating is 40 V for transient conditions such as load dump, but sustained operation above 28 V risks permanent damage. Designers must ensure TVS clamping or filtering limits VS excursion within this window during battery transients.
How is dead time adjusted, and what is its functional range?
Dead time is set by connecting an external resistor between the DT pin and GND. Values from 10 kΩ to 100 kΩ yield dead times from 100 ns to 500 ns, respectively. This adjustment occurs in hardware without MCU intervention, ensuring deterministic timing even during firmware resets or communication loss.
Does the TLE7184F3VXUMA1 support both sensored and sensorless BLDC commutation?
Yes - the IC provides all necessary gate drive, current sensing (via ISP/ISN/ISO), and diagnostic signals (TEMP, ERR, SCDL) required for either method. Sensorless operation relies on external zero-crossing detection circuitry; sensored operation uses Hall or encoder signals fed to the IHx/ILx inputs for synchronized switching.
Can the VREG output power an external CAN transceiver?
No - the VREG pin delivers 3.3 V at up to 150 mA for microcontroller core logic only. CAN transceivers typically require isolated or separately regulated 5 V or 3.3 V supplies with higher surge immunity; using VREG for this purpose violates the device's electrical specifications and compromises EMI robustness.
