Product details
Overview
TLE9185QXXUMA1 from Infineon is an automotive-qualified BLDC motor driver IC integrating a 5 V/250 mA LDO, three half-bridge gate drivers for external N-channel MOSFETs, one configurable current sense amplifier, SPI interface with CRC, and comprehensive diagnostics including open-load detection, overtemperature protection, and window watchdog. It operates with a 5.0 V microcontroller in engine cooling fan control systems.
For engineers reviewing the TLE9185QXXUMA1 datasheet, TLE9185QXXUMA1 pinout, TLE9185QXXUMA1 application, or TLE9185QXXUMA1 equivalent, key selection criteria include PWM frequency support up to 25 kHz, adaptive gate timing regulation, drain-source monitoring capability, and AEC-Q100 qualification for automotive motor control.
Technical Context
The device implements a state machine with seven operational modes (Init, Normal, Stop, Sleep, Restart, Fail-Safe, Software Development), enabling precise power-state management across vehicle operating conditions. Each mode defines distinct behavior for gate drive enablement, current consumption, wake-up sources, and fault response.
Gate driver operation supports both static activation and PWM modes with active free-wheeling, configurable pre-charge/pre-discharge timing, and slam mode for emergency shutdown. The integrated CSA provides low-side current sensing with programmable gain for overcurrent and stall detection.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 4.5 V to 28 V - supports wide automotive battery voltage range including cold-crank conditions. |
| LDO Output | 5.0 V ±2%, 250 mA - powers external MCU and peripherals without additional regulator. |
| PWM Frequency Max | 25 kHz - enables high-resolution motor speed control while minimizing audible noise. |
| SPI Interface | 32-bit with CRC - ensures robust configuration and diagnostic data exchange with host controller. |
| Quiescent Current | ≤15 µA in Sleep Mode - meets stringent automotive low-power requirements during vehicle off-state. |
| Thermal Protection | Overtemperature shutdown at 175 °C - prevents thermal runaway under overload or cooling failure. |
| AEC-Q100 Grade | Grade 0 (−40 °C to +150 °C) - qualified for under-hood applications including engine cooling fans. |
Pinout & Package
Package: PG-VQFN-48-79 - leadless exposed-pad QFN with optical lead tip inspection support and RoHS compliance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD | Main supply input | Accepts 4.5–28 V battery input; powers internal regulators and gate drivers. |
| VCC | 5 V LDO output | Provides regulated 5 V supply for external MCU and logic; max 250 mA load. |
| CSA_OUT | Current sense amplifier output | Analog voltage proportional to motor phase current; gain configurable via SPI. |
| INxH / INxL (x=1–3) | PWM inputs | Six dedicated inputs accepting high-side and low-side PWM signals for full 3-phase control. |
| OUTxH / OUTxL (x=1–3) | Half-bridge outputs | Drive external N-channel MOSFETs; each pair forms one half-bridge leg for BLDC commutation. |
| RESET_N | Reset output | Open-drain signal indicating device reset status; used for system-level fault coordination. |
| INT_N | Interrupt output | Active-low interrupt flag signaling faults (overtemp, short circuit, watchdog timeout). |

Key Features
| Feature | Design Value |
|---|---|
| Adaptive gate timing control | Regulates MOSFET turn-on/turn-off delays in real time to minimize switching losses during PWM operation. |
| Configurable cyclic wake | Periodic wake-up from Stop/Sleep modes at user-defined intervals (1 ms to 65 s) for low-power monitoring. |
| Drain-source monitoring | Detects open-load and short-to-battery/ground faults on all six half-bridge terminals without external components. |
| Reverse battery protection control | Drives external MOSFET to block reverse polarity connection, preventing damage during service. |
| Slam mode | Hardware-initiated immediate gate shutdown across all half-bridges for emergency motor stop (e.g., collision event). |

Equivalent & Alternatives
The following parts are listed as comparable options for similar BLDC driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DRV3205-Q1 | Integrated MOSFETs (40 V, 3.5 A); no external FET requirement; lower peak current rating. | Better suited for compact, lower-power pumps (<100 W); lacks CSA gain configurability and cyclic wake. | Select when board space is constrained and external FETs are undesirable; verify thermal margin at full load. |
| MC33883 | Standalone gate driver only; requires external LDO, CSA, and MCU interface logic; no integrated supervision. | Used in legacy designs where discrete architecture allows custom fault-handling logic. | Choose only when full architectural control is required and BOM cost is secondary to design flexibility. |
Compared with DRV3205-Q1 and MC33883, TLE9185QXXUMA1 delivers higher integration (LDO, CSA, watchdog, wake logic), superior diagnostic coverage (drain-source monitoring, slam mode), and AEC-Q100 Grade 0 rating-making it optimal for new automotive BLDC designs demanding functional safety and reduced component count.

FAQ
What is the maximum allowable ambient temperature for continuous operation?
The TLE9185QXXUMA1 is rated for continuous operation up to +125 °C ambient temperature when mounted on a PCB with recommended copper pour and thermal vias per Infineon's layout guidelines. Its internal overtemperature protection triggers at 175 °C junction temperature, providing safety margin under transient overload or reduced airflow conditions.
Does the device support sensorless BLDC commutation?
No-the TLE9185QXXUMA1 does not include back-EMF sensing or rotor position estimation circuitry. It functions as a gate driver and system manager; commutation timing must be provided externally by the host MCU via the six PWM inputs or SPI-configured lookup tables.
Can the current sense amplifier be used for both overcurrent protection and motor stall detection?
Yes-the CSA provides analog output scalable via SPI-configurable gain (10×, 20×, 40×, 80×). This enables simultaneous use for fast overcurrent shutdown (via comparator thresholds) and slower stall detection through sustained current deviation analysis in the host MCU firmware.
Is the SPI interface compatible with standard 3.3 V microcontrollers?
Yes-the SPI pins (SCLK, MOSI, MISO, CSN) are 5 V tolerant and operate with 3.3 V logic levels when VCC = 5 V. The device accepts 3.3 V input signals and drives 5 V-compatible outputs, eliminating level-shifting requirements in mixed-voltage automotive systems.
