Product details
Overview
TLE9241QUXUMA1 from Infineon is an automotive-qualified transmission I/O IC integrating four two-wire Hall position sensor interfaces, four two-wire Hall speed sensor interfaces (with digital speed/direction outputs), two programmable high-side gate drivers for safety solenoid control, and one reverse-polarity-protected high-side switch driver for module sleep-state power cutoff. It features 16-bit SPI interface, integrated charge pump, and overtemperature/short-circuit protection. Used in automatic transmission control modules for solenoid actuation and sensor signal conditioning.
For engineers reviewing the TLE9241QUXUMA1 datasheet, TLE9241QUXUMA1 pinout, TLE9241QUXUMA1 application, or TLE9241QUXUMA1 equivalent, key selection considerations include Hall sensor interface count (8 total), dual high-side gate drive channels with programmable overcurrent thresholds, reverse-polarity protected power switch capability, SPI-based diagnostics, and AEC-Q100 qualification for powertrain environments.
Technical Context
The device implements a dedicated transmission I/O architecture with segregated analogue and digital ground domains (GNDA/GNDD), enabling noise-immune Hall sensor signal acquisition. Its eight two-wire Hall interfaces support both position and speed sensing via configurable SRx (analogue) and SDx (digital) outputs, while maintaining independent fault reporting per channel via SPI status registers.
Two high-side gate drivers (HSIN1/HSIN2) provide PWM-capable control of external n-channel MOSFETs for solenoid power delivery, each with dedicated overcurrent sense paths (SENSHx/SENSLx) and disable inputs (HSDISx). The third high-side driver (GRBH/GRBL) operates in anti-serial configuration to enable reverse-polarity protected main power switching under INH control.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VS Supply Range | 5.5 V to 40 V - supports wide battery voltage range including cold-crank and load-dump conditions in 12 V automotive systems. |
| VDD Supply | 4.75 V to 5.25 V - regulated internal logic supply enabling stable SPI and register operation. |
| Hall Interfaces | 8 × two-wire - four configurable for position sensing (SENSH/SENSL), four for speed/direction (SRx + SDx), all with short-to-supply protection. |
| High-Side Drivers | 2 × programmable current-limited - each with adjustable overcurrent threshold and SPI-accessible output state feedback. |
| SPI Interface | 16-bit, full-duplex - enables real-time configuration, diagnostic readback (sensor states, faults, temperature), and register access without external glue logic. |
| Charge Pump | Integrated - generates gate drive voltage above VS for n-channel MOSFET control without external boost circuitry. |
| AEC-Q100 Grade | Grade 0 (−40 °C to +150 °C junction) - qualified for under-hood transmission control module placement. |

Key Features
| Feature | Design Value |
|---|---|
| Eight two-wire Hall interfaces | Enables direct connection of up to eight Hall sensors without external biasing or signal conditioning, reducing BOM and PCB area in transmission position/speed sensing. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transmission I/O applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLE9240QUXUMA1 | Omits reverse-polarity protected switch driver (no GRBH/GRBL); retains 8 Hall interfaces and 2 high-side drivers. | Not suitable for modules requiring main power cutoff with reverse polarity protection. | Select when sleep-state power management is handled externally or not required. |
| MC33816AEKR2 | Offers 6 Hall interfaces, 3 high-side drivers, no integrated charge pump; requires external boost for n-MOSFET gate drive. | Lacks anti-serial switch capability and reverse polarity protection; different SPI register map and fault reporting structure. | Consider for cost-sensitive designs where fewer Hall channels suffice and external gate drive is acceptable. |
Compared with TLE9240QUXUMA1 and MC33816AEKR2, the TLE9241QUXUMA1 uniquely combines full 8-channel Hall support, dual programmable high-side drivers, and reverse-polarity protected main switch in a single AEC-Q100 Grade 0 package-making it optimal for integrated transmission control modules requiring comprehensive I/O consolidation and functional safety compliance.

FAQ
What is the maximum number of Hall sensors supported by the TLE9241QUXUMA1?
The TLE9241QUXUMA1 supports up to eight two-wire Hall effect sensors: four dedicated to position sensing (with SENSH/SENSL pairs) and four configurable for either position or speed sensing (with SRx analogue and SDx digital outputs). All eight channels feature short-to-supply protection and individual SPI-accessible status reporting.
Does the TLE9241QUXUMA1 require an external charge pump capacitor?
Yes - the CP pin (Pin 26) requires an external ceramic capacitor (typically 100 nF, X7R, 16 V) connected between CP and GNDD to stabilize the internal charge pump. This capacitor enables generation of gate drive voltage above VS for reliable n-channel MOSFET turn-on across the full 5.5–40 V supply range.
How does the reverse-polarity protected high-side switch function?
The GRBH and GRBL pins drive the gates of two anti-serial n-channel MOSFETs. When enabled, this configuration blocks reverse battery connection while allowing forward current flow. Internal logic ensures only one MOSFET conducts at a time, preventing shoot-through, and thermal foldback limits power dissipation during sustained overload.
Is the TLE9241QUXUMA1 compatible with 3.3 V microcontrollers?
Yes - the VIO pin (Pin 22) accepts 3.1–5.25 V, allowing direct interface with 3.3 V SPI peripherals. MISO, MOSI, SCK, and CSN are VIO-referenced and tolerate 3.3 V logic levels. However, HSINx, HSDISx, and INH inputs are VS-referenced and require level-shifting if driven by 3.3 V GPIOs.
