Product details
Overview
TLE7184F3VXUMA2 from Infineon Technologies is an automotive-grade system IC for B6 (3-phase bridge) brushless DC motor control, integrating six N-channel MOSFET gate drivers, a 3.3 V low-dropout voltage regulator (VREG), analog current-sense amplifier, VDH switch, and comprehensive protection diagnostics. It supports 0–94% PWM duty cycle at 25 kHz, operates from 5.5–28 V VS supply, and features adjustable dead time and short-circuit detection thresholds. Used in electric power steering (EPS), HVAC blower, and radiator fan modules.
For engineers reviewing the TLE7184F3VXUMA2 datasheet, TLE7184F3VXUMA2 pinout, TLE7184F3VXUMA2 application, or TLE7184F3VXUMA2 equivalent, key selection criteria include bootstrap-capable high-side drive capability, integrated 3.3 V µC supply, analog temperature monitoring, ERR pin fault signaling, and AEC-Q100 qualification for under-hood deployment.
Technical Context
The TLE7184F3VXUMA2 implements a fully integrated B6 motor driver architecture with three independent half-bridge stages, each featuring floating high-side drivers using bootstrap capacitors (BH1–BH3), dedicated gate outputs (GH1/GL1–GH3/GL3), and source sensing (SH1–SH3, SL). It embeds a precision current-sense opamp (ISP/ISN/ISO) with gain and offset calibrated for shunt-based phase current measurement.
Its diagnostic subsystem includes analog temperature output (TEMP), open-drain ERR flag, and layered protection: VS_UVLO, VDD_UVSD, VREG_UVSD, IOV_OVSD, OTSD, SCP via SCDL, OCSD via current sense, and shoot-through prevention via programmable DT input. All digital interfaces (IFMA, IFuC, INH, INHD) operate at 3.3 V logic levels with internal pull-ups.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VS Supply Range | 5.5 V to 28 V - supports wide automotive battery range including cold-crank (6 V) and load-dump (28 V) conditions. |
| VREG Output | 3.3 V ±2%, 150 mA - powers external microcontroller directly; low dropout enables stable operation down to VS = 5.5 V. |
| PWM Frequency Support | Up to 25 kHz - enables smooth torque control in BLDC motors without audible noise in EPS and HVAC applications. |
| Dead Time Adjustment | Programmable via resistor on DT pin - prevents shoot-through by setting minimum off-time between complementary HS/LS switching. |
| Short-Circuit Detection | Analog-adjustable threshold via SCDL pin - allows fine-tuning of overcurrent trip level per application current rating and shunt value. |
| Temperature Monitoring | Analog TEMP output (0.8 V @ 25 °C, –2.2 mV/K) - enables real-time junction temperature estimation without external sensor. |
| AEC-Q100 Grade | Grade 1 (–40 °C to +125 °C ambient) - qualified for under-hood automotive environments with full thermal derating support. |

| IL1–IL3 (Pins 38,40,42) | Low-side control inputs | Active-high logic inputs controlling GL1–GL3; internally pulled up; synchronized with IHx for B6 commutation. |
| BH1–BH3 (Pins 24,20,16) | Bootstrap capacitor positive terminals | Charge path for floating high-side gate drivers; each requires dedicated 100 nF–220 nF ceramic bootstrap capacitor. |
| GH1–GH3 (Pins 23,19,15) | High-side gate drive outputs | Source-follower outputs driving N-channel MOSFET gates; rated for 1 A peak sink/source current. |
| GL1–GL3 (Pins 21,17,13) | Low-side gate drive outputs | Ground-referenced outputs; capable of 1.5 A peak sink current for fast MOSFET turn-off. |
| SH1–SH3 (Pins 22,18,14) | High-side source sense nodes | Return paths for bootstrap charging; connect directly to respective MOSFET source pins for accurate high-side referencing. |
| SL (Pin 10) | Common low-side source node | Single connection point for all three low-side MOSFET sources; critical for shunt-based current sensing topology. |
| ISP/ISN (Pins 45/44) | Current-sense amplifier inputs | Differential inputs for external shunt resistor; ISP connects to shunt high side, ISN to low side (SL). |
| ISO (Pin 46) | Current-sense amplifier output | Single-ended output referenced to AGND; gain and offset factory-trimmed for ±50 mV input range. |

| ERR (Pin 34) | Open-drain error flag | Active-low signal asserted during any fault (OTSD, UV, OV, SCP, OCSD); requires external pull-up to VDD. |
| INH (Pin 27) | System enable/wake-up input | Active-high input enabling full IC operation; wake-up source for sleep-mode recovery in low-power EPS systems. |
| INHD (Pin 47) | INH status indicator | 3.3 V CMOS output mirroring INH state; used for µC status monitoring or interlock logic. |
| VDHS (Pin 4) | Switched VDH output | Open-drain output sourcing VDH when INH = HIGH; disabled in sleep mode to reduce leakage current. |
| SCDL (Pin 9) | Short-circuit detection level | Analog input setting SCP threshold via voltage divider; 0–1.2 V range maps to 10–100 mV shunt voltage trip points. |
| DT (Pin 11) | Dead time adjustment | Resistor-to-GND sets minimum off-time between complementary HS/LS switching; prevents cross-conduction. |
| GND (Pins 1,12,26,32,35) | Power and analog ground | Multiple GND pins minimize impedance; exposed pad must be soldered to solid ground plane for thermal and EMI performance. |

FAQ
What is the maximum allowable VS supply voltage for continuous operation?
The TLE7184F3VXUMA2 supports VS up to 28 V continuously, covering automotive load-dump conditions per ISO 7637-2 Pulse 5a. Absolute maximum rating is 36 V for transient events ≤20 ms. Operation above 28 V requires external clamping and is not recommended for sustained use due to thermal stress on internal regulators and drivers.
How is the short-circuit detection threshold set and verified?
The SCDL pin accepts a DC voltage (0–1.2 V) that maps linearly to shunt voltage trip thresholds from 10 mV to 100 mV. Threshold accuracy is ±15% over temperature; verification requires measuring ISO output during controlled overcurrent events and correlating with shunt voltage using oscilloscope capture at ISN/ISP nodes.
Does the TLE7184F3VXUMA2 support 100% duty cycle operation?
No-the device limits maximum duty cycle to 94% at 25 kHz to ensure sufficient off-time for bootstrap capacitor recharge in high-side drivers. Attempting 100% duty cycle causes GHx outputs to collapse due to insufficient BHx charging, resulting in loss of high-side conduction and ERR assertion.
Can the VREG output power external circuitry beyond the gate drivers?
VREG (Pin 7) is rated for 150 mA total load and is intended solely for gate driver stages. Connecting additional loads (e.g., sensors, level shifters) risks undersupply, thermal overload, and instability. External circuitry must be powered from VDD (3.3 V, 150 mA) or an independent regulator.
