TLE9241QUXUMA1 Обзор
A solenoid driver IC is a specialized mixed-signal semiconductor that translates digital commands from a transmission control unit (TCU) into precisely regulated analog currents flowing through inductive loads such as pressure-control valves, shift valves, and lock-up clutches. As a category, it sits within the broader power-management IC (PMIC) hierarchy: gate driver -> solenoid driver -> motor/actuator driver -> PMIC -> semiconductor. By replacing discrete PWM drive circuitry and analog current-sense op-amps with a single highly integrated IC, the TLE9241 family dramatically reduces PCB area and improves diagnostic coverage in transmission ECUs.
Key features of the TLE9241QUXUMA1 include integrated closed-loop current regulation via internal PWM generation, parallel SPI control of multiple devices for multi-valve TCU scaling, comprehensive fault diagnostics (open-load, short-to-ground, short-to-battery, over-temperature), and an operating temperature range of -40 °C to +150 °C suitable for under-hood automotive environments. The 7.5 A peak current capability per channel supports the high forces required by proportional pressure-control valves during gear shifts.
Typical end applications are 6-, 7-, 8-, and 9-speed automatic transmissions (DCT, AT, CVT, e-clutch), electro-mechanical power steering (EMPS) actuation where similar proportional solenoid control is used, and dual-clutch module valve bodies. The Infineon TLE9241QU datasheet documents the SPI register map, dither/waveform control, and EMC behavior relevant for these transmission modules.
When designing with the TLE9241QUXUMA1, allocate a 100 nF decoupling capacitor directly on each VS pin and a 10 µF bulk reservoir near the package, plus an exposed-pad thermal land for heat spreading during sustained PWM operation. The SPI bus must be pulled up to the logic VIO rail and protected with TVS diodes for harness transients exceeding ISO 7637-2.
This page synthesizes current distributor stock levels, parametric drop-in alternatives, SPI register guidance, and EMC layout considerations that go beyond the manufacturer datasheet, giving transmission engineers a single point of reference for sourcing and design-in.

Типичное применение
TLE9241QUXUMA1 подходит для 6 применениеs: 6-9 Speed Automatic Transmission (AT) Valve Body, Dual-Clutch Transmission (DCT) Module Control, Continuously Variable Transmission (CVT) Solenoid Control, Electro-Mechanical Power Steering (EMPS) Valve Actuation, Automated Manual Transmission (AMT) Pneumatic/Hydraulic Valves, Transmission Oil Pump Brushless DC Drive (Companion Function).
6-9 Speed Automatic Transmission (AT) Valve Body
The TLE9241QUXUMA1 directly drives up to seven proportional pressure-control solenoid valves inside an automatic transmission valve body. Its 7.5 A per-channel peak current and internal closed-loop PWM current regulation let a TCU command precise hydraulic line pressures for shift feel and torque-on-demand response. Unlike discrete MOSFET-driver pairs, the integrated Hall-effect inputs capture rotational speed signals from 8 sensors without external signal-conditioning op-amps, reducing PCB area by ~40%. Designers place a 100 nF X7R capacitor on each VS pin within 2 mm of the IC and bond the exposed pad to a 4-layer inner copper pour for the thermal dissipation needed under sustained 2 kHz PWM.

Dual-Clutch Transmission (DCT) Module Control
In a dual-clutch transmission, the TLE9241QUXUMA1 drives the two clutch-pack proportional valves plus 4-5 shift valves, replacing a discrete H-bridge array. The 6-low-side + 1-high-side topology maps natively to a DCT's pressure architecture, and the parallel SPI mode lets multiple TLE9241 devices share a single TCU bus. Each channel's current setpoint is updated in 8-bit resolution over SPI at 1 ms loop time, enabling millisecond-level clutch-fill synchronization. Design tip: add a TVS diode (P6KE33A) on VBAT to meet ISO 7637-2 pulse 5 transient immunity.
Рекомендуется
Continuously Variable Transmission (CVT) Solenoid Control
CVT modules rely on high-resolution solenoid current control for primary/secondary pulley clamping forces and torque-sensing valves. The TLE9241QUXUMA1's internal PWM controller delivers 12-bit effective current resolution across its 7.5 A range, achieving sub-mA setpoint accuracy for smooth ratio transitions. The 8 Hall-effect inputs support integrated speed sensing from both pulleys and the chain drive, feeding the TCU algorithm in real time. Layout guidance: separate the analog Hall sensor traces (HV sense lines) from the solenoid flyback traces by at least 4 mm to avoid coupling.
Рекомендуется
Electro-Mechanical Power Steering (EMPS) Valve Actuation
Some EMPS architectures still use proportional hydraulic valves for force feedback, where the TLE9241QUXUMA1 drives the steering-valve solenoids with sub-mA current precision. The -40 °C to +150 °C AEC-Q100 qualification handles under-hood ambient, and the SPI diagnostic register (open-load, short-to-battery, over-temperature) supports ASIL-B functional-safety decomposition. Compared to discrete solutions, the integrated diagnostics reduce BOM count by ~25 components per steering unit and shrink PCB area by ~30%.
Рекомендуется
Automated Manual Transmission (AMT) Pneumatic/Hydraulic Valves
AMT systems use electro-pneumatic or electro-hydraulic actuators for clutch and gear-fork control, requiring 5-7 proportional valves with high-current capability. The TLE9241QUXUMA1's 7 channels and 7.5 A peak current match AMT actuator demands precisely. The parallel-mode SPI allows daisy-chaining of multiple TLE9241 devices for 14-21 valve configurations in heavy-truck AMT applications. The exposed-pad package ensures thermal performance during continuous low-speed maneuvering where valves remain energized.
Рекомендуется
Transmission Oil Pump Brushless DC Drive (Companion Function)
While the TLE9241QUXUMA1 primarily drives solenoids, its SPI bus architecture enables integration with companion BLDC drivers in the same TCU module. The TLE9180D32QKXUMA1 (Infineon BLDC gate driver) handles the auxiliary oil-pump motor, sharing the SPI bus with the TLE9241QUXUMA1 through chip-select addressing. Designers gain a unified diagnostic chain and reduce harness weight by integrating pump and valve control on a single PCB. Combined thermal budget must keep both ICs below +150 °C junction.

Заметки по проектированию
Estimated: at sustained 2 kHz PWM driving 1.0 A average per channel on all 7 channels, total power dissipation is ~4-6 W. The PG-TQFP-48-9 with exposed pad requires a 4-layer PCB inner copper pour (at least 4 cm²) tied to the thermal pad to keep junction temperature rise below 50 °C. Without proper thermal design, the die will exceed +150 °C under hot-soak conditions.
Place a 100 nF X7R decoupling capacitor within 2 mm of each VS pin, and a 10 µF bulk reservoir (low-ESR tantalum or polymer) within 5 mm of the package. Separate the high-current solenoid traces (carrying up to 7.5 A) from the analog Hall sensor traces by at least 4 mm to prevent coupling. The exposed thermal pad must be soldered with a 0.5 mm pitch thermal via array to an inner ground plane.
Add a TVS diode (e.g., P6KE33A) on the VBAT pin to meet ISO 7637-2 pulse 5 (load-dump) transient immunity. Place the SPI traces (SCLK, SDI, SDO, CSN, INT, RST) on an inner signal layer with ground reference, and add 33 Ω source-termination resistors on SCLK and SDO to dampen ringing at 10 MHz SPI clock. Pull CSN high with a 10 kΩ resistor to VIO during MCU reset to prevent spurious writes.
Do not connect the exposed thermal pad to any signal trace - it must bond directly to the ground plane with multiple thermal vias. The Hall sensor inputs are 5 V CMOS logic level; never apply voltage outside 0-VIO range. If a Hall sensor wire is disconnected (open-load), the corresponding input will float - use external pull-downs of 10 kΩ if harness disconnection is possible in the field. SPI clock should not exceed 10 MHz per the datasheet AC characteristics.
