Product details

Overview

TLE7184FXUMA2 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 (VREG), analog current-sense amplifier, temperature monitoring, and comprehensive protection logic. It supports 0–94% PWM duty cycle at 25 kHz, operates up to 125 °C ambient, and targets brushless DC (BLDC) and brushed DC motor control in powertrain and chassis systems.

For engineers reviewing the TLE7184FXUMA2 datasheet, TLE7184FXUMA2 pinout, TLE7184FXUMA2 application, or TLE7184FXUMA2 equivalent, key selection criteria include bootstrap-based high-side drive capability, adjustable short-circuit detection threshold via SCDL pin, analog temperature output on TEMP, ERR open-drain fault signaling, and AEC-Q100 qualification for automotive reliability.

Technical Context

The TLE7184FXUMA2 implements three independent floating high-side/low-side driver stages with integrated level shifters and shoot-through protection enforced by programmable dead time (DT pin). Each phase includes dedicated GHx/GLx outputs, BHx bootstrap supply pins, and SHx source sensing nodes for accurate high-side current reconstruction.

It integrates a precision current-sense op-amp (ISP/ISN/ISO) with gain of 20 V/V and offset < ±1 mV, enabling shunt-based motor phase current measurement. Protection functions are hardware-asserted-including OTSD, VS_UVLO, VDD_UVSD, IOV_OVSD, SCP, and OCSD-feeding into a single open-drain ERR output with diagnostic latching via RGS.

Key Specifications

Parameter	Value and Actual Design Meaning
PWM Frequency	Up to 25 kHz - supports standard BLDC commutation timing without audible noise or excessive switching loss.
Duty Cycle Range	0–94% - enables full-range speed control while preserving minimum off-time for bootstrap capacitor recharge.
VREG Output	5.0 V ±2%, 150 mA - powers external microcontroller directly, eliminating need for separate LDO in ECU designs.
Current Sense Gain	20 V/V, ±1% gain error - delivers accurate, low-offset phase current feedback for closed-loop torque control.
Operating Temp	−40 °C to +125 °C ambient - qualified per AEC-Q100 Grade 0, suitable for under-hood motor actuator applications.
ERR Output Type	Open-drain, 20 mA sink - interfaces directly with µC GPIO for fault polling or interrupt-driven diagnostics.
Short-Circuit Threshold	Analog-adjustable via SCDL pin (0.2–1.2 V range) - allows precise tuning of overcurrent trip point per motor winding resistance.

Pinout & Package

PG-VQFN-48 package with exposed thermal pad (connected to GND), 7 × 7 mm body, 0.5 mm pitch. Pin count: 48 leads + thermal pad. RoHS-compliant, halogen-free, AEC-Q100 qualified.

Pin/Terminal	Circuit Role	Design Meaning
GH1–GH3	High-side gate driver outputs	Drive gates of N-channel MOSFETs in phases 1–3; each floats up to VS + 65 V with internal level shifter.
GL1–GL3	Low-side gate driver outputs	Sink/source 1.5 A peak to switch low-side MOSFETs; referenced to SL common source node.
BH1–BH3	Bootstrap capacitor positive terminals	Supply floating high-side drivers; require external 100 nF ceramic capacitors between BHx and SHx.
SH1–SH3	High-side source sense nodes	Connect to MOSFET source pins; enable high-side current sensing and bootstrap voltage monitoring.
IL1–IL3 / IH1–IH3	Logic-level input pins	Active-high low-side (ILx) and active-low high-side (IHx) PWM inputs; support standard µC GPIO interface.
SCDL	Analog short-circuit threshold input	Voltage divider sets trip point (0.2–1.2 V); determines current limit before OCSD activation.
TEMP	Analog temperature output	Linear 10 mV/°C output (0 V @ −40 °C) - enables real-time junction temperature monitoring without external sensor.
ERR	Open-drain fault indicator	Asserts low on any fault (OTSD, UVLO, OVSD, SCP); latched until RGS pin pulsed high.

Key Features

Feature	Design Value
Adjustable dead time	Configured via external resistor on DT pin (100 ns–2 µs range), preventing shoot-through during phase commutation.
Analog temperature monitoring	Integrated bandgap sensor with linear 10 mV/°C output on TEMP pin - eliminates discrete thermal sensor and ADC channel.
Hardware-based short-circuit protection	Detects overcurrent via SHx node voltage; triggers OCSD within 1.2 µs - faster than µC-based software response.
VREG controller with sleep mode	5 V regulator shuts down in sleep (INH = low), reducing quiescent current to < 100 µA - meets automotive static current requirements.
Single-pin fault reporting	ERR pin aggregates 15+ fault conditions (OTSD, UVLO, OVSD, SCP, etc.) into one open-drain signal - simplifies µC interrupt handling.

Applications

Electric Power Steering (EPS)

IC Role / Device Role / Timing Role: System-level motor driver with embedded 5 V VREG, analog temperature output, and ERR fault aggregation for EBB ECU integration.

Use Value: TEMP pin's 10 mV/°C linearity enables precise junction temperature tracking - critical for thermal derating and ASIL-B compliance.

Automotive HVAC Blower

Seat Ventilation Motor Control

Use Scenario: Variable-speed 3-phase fan motor in climate control system, requiring smooth low-noise operation and energy-efficient partial-load performance.

IC Role / Device Role / Timing Role: B6 bridge driver with 25 kHz PWM support and 0–94% duty cycle range - enables quiet commutation and wide-speed regulation.

Use Value: Adjustable SCDL threshold allows tuning to motor winding resistance, avoiding nuisance trips during startup inrush current.

Use Scenario: Small-form-factor brushed DC or BLDC seat ventilation motor requiring compact, thermally robust driver with diagnostic capability.

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	Higher peak output current (2.5 A vs. 1.5 A), no integrated VREG or analog temperature output.	Requires external 5 V LDO and thermal sensor; better suited for high-current inverters where headroom matters more than integration.	Select when gate drive strength >1.5 A is required and system already provides 5 V rail and temperature sensing.
MC33883	Legacy 3-phase driver with fixed 1.2 µs dead time, no SCDL adjustment, and no analog TEMP output.	Lacks programmable protection thresholds and real-time thermal feedback - limited to simpler, cost-sensitive non-safety-critical motors.	Select only for legacy redesigns where footprint compatibility and minimal feature set are prioritized over diagnostics.

Compared with DRV3205-Q1 and MC33883, the TLE7184FXUMA2 offers superior integration (VREG, TEMP, ISP), finer protection tuning (SCDL, DT), and tighter AEC-Q100 Grade 0 qualification - making it optimal for new ASIL-B motor control designs demanding compactness and diagnostic depth.

FAQ

What is the maximum allowable bootstrap capacitor voltage on BH1–BH3 pins?

The BH1–BH3 pins support bootstrap capacitor voltages up to VS + 65 V, with VS rated up to 28 V. This allows safe high-side gate drive in 24 V automotive systems with transient spikes up to 42 V, provided external 100 nF ceramic capacitors are used and layout minimizes parasitic inductance.

How does the SCDL pin adjust short-circuit detection threshold?

The SCDL pin accepts an analog voltage (0.2–1.2 V) from a resistor divider across the shunt. Internally, this sets the reference for overcurrent comparison against the SHx node voltage. A 0.5 V input corresponds to ~25 A trip threshold with 5 mΩ shunt, enabling precise calibration per motor phase resistance and thermal margin.

Can the TLE7184FXUMA2 drive both BLDC and brushed DC motors?

Yes - its six independent gate drivers support B6 bridge configurations for 3-phase BLDC commutation, and can be reconfigured for dual H-bridge brushed DC control (e.g., two motors or bidirectional single motor). The datasheet explicitly lists both use cases, and INH/INHD logic supports wake-up sequencing for either topology.

Is the TEMP pin output ratiometric or absolute?

The TEMP pin provides an absolute analog voltage output: 0 V at −40 °C, increasing linearly at 10 mV/°C (e.g., 1.25 V at +85 °C). It is not ratiometric to VDD or VREG - calibration requires only a single-point offset correction at room temperature, simplifying µC ADC implementation.
