Product details
Overview
TLE7184FXUMA1 from Infineon Technologies is an automotive-grade System IC for B6 (3-phase bridge) motor drives, integrating six N-channel MOSFET gate drivers, a 5 V low-dropout regulator for microcontroller supply, analog temperature monitoring, current-sense op-amp, and comprehensive protection including overtemperature shutdown, short-circuit detection, and shoot-through prevention. It supports 0–94% PWM duty cycle at 25 kHz in BLDC and brushed DC motor control.
For engineers reviewing the TLE7184FXUMA1 datasheet, TLE7184FXUMA1 pinout, TLE7184FXUMA1 application, or TLE7184FXUMA1 equivalent, key selection considerations include bootstrap-based high-side drive capability, adjustable dead time via external resistor, analog short-circuit threshold setting via SCDL pin, and AEC-Q100 qualification for under-hood automotive use.
Technical Context
The TLE7184FXUMA1 implements a fully integrated B6 gate driver architecture with three independent floating high-side/low-side channel pairs (GH1/GL1 through GH3/GL3), each driven by dedicated level shifters and protected by shoot-through logic and programmable dead time (DT pin). It uses bootstrap capacitors (BH1–BH3) for high-side gate bias generation and includes internal charge pumps to sustain operation during 100% duty cycle conditions.
It integrates a precision current-sense amplifier (ISP/ISN/ISO) with rail-to-rail output, a 5 V LDO (VDD) delivering up to 150 mA for MCU power, and a separate VREG output (7 V typical) for gate driver stages. Diagnostic functions include open-drain ERR reporting, analog TEMP output, and multiple UV/OV/OC fault latching mechanisms compliant with ISO 26262 ASIL-B support requirements.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage (VS) | 5.5 V to 28 V - supports wide automotive battery range including cold-crank (6 V) and load-dump (40 V transient tolerant) |
| Gate Drive Output Current | ±1.5 A peak - sufficient to drive 10 nF gate capacitance at ≤100 ns rise/fall times for fast-switching MOSFETs |
| Dead Time Adjustment | Programmable via DT pin resistor - enables precise timing control between complementary HS/LS switching to prevent shoot-through |
| Short-Circuit Detection Threshold | Analog-adjustable via SCDL pin voltage - sets fixed OCSD trip point from 0.2 V to 1.2 V, enabling custom current-limit tuning |
| Temperature Monitoring | Analog TEMP output (0.5 V @ 25 °C, –2 mV/K) - provides linear, calibrated junction temperature feedback for thermal management |
| Diagnostic ERR Pin | Open-drain, active-low - latches and reports combined fault status (OTSD, OCSD, UVLO, OVSD) for system-level error handling |
| AEC-Q100 Grade | Grade 1 (–40 °C to +125 °C ambient) - qualified for engine compartment and transmission control applications |
Pinout & Package
Package: PG-VQFN-48 (7 mm × 7 mm, 0.5 mm pitch) with exposed thermal pad soldered to PCB ground plane for enhanced thermal dissipation in high-power motor drive environments.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| BH1–BH3 | Bootstrap capacitor positive terminals | Provide floating supply for high-side gate drivers; require external 100 nF ceramic capacitors per phase |
| GH1–GH3 / GL1–GL3 | High-side and low-side gate drive outputs | Directly interface with N-channel MOSFET gates; ±1.5 A drive strength ensures fast turn-on/turn-off |
| SH1–SH3 | High-side source connections | Return path for bootstrap current; must be connected to respective phase node (motor winding connection point) |
| SL | Common low-side source node | Reference point for all low-side MOSFET sources; connects to motor star point or shunt resistor ground |
| ISP/ISN/ISO | Current-sense amplifier inputs/output | Differential input pair with rail-to-rail output; enables bidirectional motor current measurement using single shunt resistor |
| TEMP | Analog temperature sensor output | Linear voltage output proportional to die temperature (0.5 V @ 25 °C, –2 mV/K); used for thermal derating or fault prediction |
| ERR | Open-drain diagnostic output | Active-low latched fault indicator; requires external pull-up; asserts on any enabled protection event (OTSD, OCSD, UVLO, etc.) |
| INH / INHD | System enable input / digital enable status output | INH wakes device from sleep; INHD mirrors INH state at 5 V logic level for MCU monitoring |
Key Features
| Feature | Design Value |
|---|---|
| Integrated 5 V LDO (VDD) | 150 mA output with tight regulation (±2%) - powers external MCU without requiring discrete regulator |
| Adjustable short-circuit protection | SCDL pin accepts 0.2–1.2 V reference - enables precise current-limit setting across varying motor and MOSFET combinations |
| Shoot-through prevention | Hardware-enforced dead time + logic interlock - eliminates risk of simultaneous HS/LS conduction even under timing skew or noise |
| Low quiescent current mode | <100 µA sleep current - extends battery life in always-on vehicle modules such as EPS or HVAC actuators |
| Green Product compliance | RoHS-compliant, halogen-free, lead-free - meets global automotive environmental standards (ELV, IMDS) |
Applications
| Electric Power Steering (EPS) | Automotive HVAC Blower |

Equivalent & Alternatives
The following parts are listed as comparable options for similar B6 motor driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BD6212F-E2 (ROHM) | Lower drive current (±0.5 A), no integrated 5 V LDO, no analog TEMP output | Limited to low-power fans or small actuators; requires external regulator and thermal sensor | Choose when cost sensitivity outweighs integration needs and thermal monitoring is not required |
| MPQ6535-AEC1 (Monolithic Power) | Includes integrated MOSFETs (6× 40 mΩ), no bootstrap requirement, but fixed 12 V max VS | Suitable only for 12 V systems; lacks analog current sense and flexible SCDL threshold adjustment | Prefer for space-constrained, lower-voltage applications where discrete MOSFET layout is impractical |
Compared with BD6212F-E2 and MPQ6535-AEC1, the TLE7184FXUMA1 uniquely combines high-current gate drive, dual regulated supplies (VDD + VREG), analog temperature and current sensing, and AEC-Q100 Grade 1 qualification - making it optimal for demanding under-hood BLDC applications requiring functional safety and thermal resilience.

FAQ
What is the maximum allowable PWM frequency for TLE7184FXUMA1?
The TLE7184FXUMA1 supports PWM frequencies up to 25 kHz with full 0–94% duty cycle range. Its gate drivers deliver ±1.5 A peak current and ≤100 ns propagation delay, enabling reliable switching at this frequency with standard 10 nF gate loads. Operation beyond 25 kHz is not characterized or guaranteed per datasheet Rev. 1.30.
How is short-circuit protection configured on the TLE7184FXUMA1?
Short-circuit protection is configured via the SCDL pin: applying a DC voltage between 0.2 V and 1.2 V sets the current threshold at which OCSD triggers. This voltage is compared against the amplified shunt signal (ISO), and a match initiates immediate shutdown. The threshold is fixed per configuration - no dynamic adjustment during runtime.
Does TLE7184FXUMA1 support 100% duty cycle operation?
Yes - the TLE7184FXUMA1 supports 100% high-side duty cycle using internal charge pump circuitry that refreshes bootstrap capacitor voltage during sustained conduction. This eliminates need for external high-side supply or complex bootstrap management in applications like static torque hold or regenerative braking phases.
What is the role of the RGS pin?
The RGS (Reset and Go-to-Sleep) pin serves two functions: pulling RGS HIGH resets all latched fault registers (e.g., ERR state), while pulling RGS LOW forces the device into low-power sleep mode. It is not an automatic wake-up trigger - INH or IFMA must be asserted separately to exit sleep and resume operation.
