Product details
Overview
TLE9185QXV33XUMA1 from Infineon is an automotive-qualified BLDC motor driver IC integrating a 3.3 V/250 mA LDO regulator, three half-bridge gate drivers for external N-channel MOSFETs, one configurable current sense amplifier (CSA), 32-bit SPI with CRC, and comprehensive diagnostics including drain-source monitoring, open-load detection, overtemperature protection, and configurable window/watchdog timers. It targets auxiliary motor control in fuel pumps, engine cooling fans, and sunroof modules.
For engineers reviewing the TLE9185QXV33XUMA1 datasheet, TLE9185QXV33XUMA1 pinout, TLE9185QXV33XUMA1 application, or TLE9185QXV33XUMA1 equivalent, key selection criteria include PWM input flexibility (6 inputs, up to 25 kHz), adaptive gate control for switching loss reduction, low quiescent current in Stop/Sleep modes, reverse battery protection support, and AEC-Q100 qualification for automotive use.
Technical Context
The TLE9185QXV33XUMA1 implements a state-machine-based control architecture with seven operational modes (Init, Normal, Stop, Sleep, Restart, Fail-Safe, Software Development), enabling precise power-state management across automotive duty cycles. Its gate drivers support both static activation and PWM operation with active free-wheeling, configurable pre-charge/discharge timing, and slam/parking braking modes.
Supervision functions include dual watchdog types (time-out and window), cyclic wake capability in all active and low-power modes, and fault reaction logic that supports state retention, restart, or fail-safe transitions based on detected conditions like overtemperature or short circuit. The integrated CSA provides gain-configurable current sensing for motor phase protection and diagnosis.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar BLDC driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STSPIN32F0B | Integrated 32-bit ARM Cortex-M0 MCU + gate drivers; no standalone LDO; lower max VS (28 V vs. TLE9185's 28 V), but lacks CSA and drain-source monitoring. | Targeted at cost-sensitive, self-contained motor control where MCU integration reduces BOM count; unsuitable for systems requiring external MCU coordination or high-fidelity current sensing. | Select when system-level integration (MCU + driver) is preferred and diagnostic depth is secondary to footprint/cost. |
| DRV3205-Q1 | Three half-bridges + 3.3 V LDO (200 mA), but no integrated CSA, no window watchdog, and only basic overtemperature protection; SPI lacks CRC. | Valid for simpler BLDC applications like radiator fans without advanced diagnostics or safety-critical CSA-based torque control. | Choose when AEC-Q100 compliance is required but functional safety level (ASIL) is not mandated, and CSA functionality is handled externally. |
Compared with STSPIN32F0B and DRV3205-Q1, the TLE9185QXV33XUMA1 delivers superior diagnostic coverage (drain-source monitoring, window watchdog, CSA), lower quiescent current in sleep states, and adaptive gate control-making it optimal for ASIL-B–capable systems requiring robust fault handling and precise motor current regulation.

FAQ
What is the maximum PWM frequency supported by the TLE9185QXV33XUMA1?
The device supports PWM operation up to 25 kHz across all six inputs, with configurable active free-wheeling and time-modulated pre-charge/pre-discharge timing to maintain efficiency and reduce EMI at high frequencies. This is confirmed in Section 9.3 of the Rev. 2.0 datasheet and validated for continuous operation within the AEC-Q100 temperature range.
Does the TLE9185QXV33XUMA1 include built-in current sensing?
Yes-it integrates one low-side current sense amplifier (CSA) with programmable gain (10–100 V/V) and rail-to-rail output. The CSA output connects directly to an external ADC or comparator and is used for overcurrent protection, torque control, and stall detection, as detailed in Sections 5.1 and 9.9 of the datasheet.
How does the TLE9185QXV33XUMA1 handle reverse battery conditions?
The IC provides dedicated control logic for an external reverse-battery protection MOSFET via the RBP pin. When reverse polarity is detected, the device asserts a signal to turn off the protection FET, preventing damage to downstream circuitry. This function is fully integrated into the supervision state machine and operates independently of MCU intervention.
Is the TLE9185QXV33XUMA1 pin-compatible with earlier TLE918x variants?
No-TLE9185QXV33XUMA1 uses the PG-VQFN-48-79 package with specific pin assignments defined in Section 3.1 of the datasheet. While functionally aligned with the TLE9183/TLE9184 families, pin mapping differs due to added features (e.g., additional PWM inputs, CSA output, enhanced watchdog), requiring PCB redesign for migration.
