Product details

Overview

TLE9842QXXUMA2 from Infineon Technologies is a 32-bit Arm® Cortex®-M0 automotive microcontroller integrating LIN transceiver, one high-side and two low-side power switches, 36 KB flash (with emulated 4 KB EEPROM), 2 KB RAM, and dual ADC subsystems (8-bit/7-ch + 10-bit/13-ch) for battery and temperature supervision - deployed in window lift motor control systems.

For engineers reviewing the TLE9842QXXUMA2 datasheet, TLE9842QXXUMA2 pinout, TLE9842QXXUMA2 application, or TLE9842QXXUMA2 equivalent, key selection criteria include AEC-Q100 Grade-1 qualification, single-supply operation from 3.0 V to 28 V, integrated VDDEXT 5 V regulator for Hall sensors, LIN BSL firmware update capability, and PWM-controlled power switch timing precision.

Technical Context

The TLE9842QXXUMA2 implements a tightly coupled system-on-chip architecture where the Arm Cortex-M0 core (25 MHz max) executes motor control firmware while dedicated hardware modules handle real-time analog acquisition and power switching. Its SCU-PM unit directly manages HS/LS switch sequencing with cycle-accurate dead-time insertion and overcurrent protection logic.

Power management integrates three regulated supplies: VDDP (5.0 V for digital logic), VDDC (1.5 V for CPU core), and VDDEXT (5.0 V externally accessible for Hall sensors). Clock generation combines an internal OSC_HP (crystal or external clock input) with PLL-based frequency synthesis to drive both CPU and peripheral timers at deterministic jitter levels.

Key Specifications

Parameter	Value and Actual Design Meaning
CPU Core	Arm Cortex-M0, 25 MHz max - enables real-time motor position control loop execution within ≤40 µs cycle time.
Flash / EEPROM	36 KB flash with 4 KB emulated EEPROM - supports field-upgradable motor profiles and calibration data retention across 100k write cycles.
ADC System	8-bit/7-ch + 10-bit/13-ch dual ADC - provides simultaneous battery voltage monitoring (VBAT_SENSE), HV monitor inputs (MON1–MON4), and temperature sensing with <±2°C accuracy.
Power Switches	1 high-side + 2 low-side switches with PWM capability - drives bidirectional DC motors in window lift applications with integrated current limiting and thermal shutdown.
LIN Interface	Integrated LIN 2.2A transceiver with LIN bootstrap loader (BSL) - enables firmware updates and diagnostics over single-wire LIN bus without external transceiver.
Supply Range	3.0 V to 28 V single supply - operates directly from vehicle battery with cold-crank tolerance down to 3.0 V and load-dump immunity up to 40 V transient.
Temperature Grade	AEC-Q100 Grade-1 (−40 °C to +125 °C) - qualified for under-hood and door module environments with full parametric validation.

Pinout & Package

VQFN-48-31 package (7 mm × 7 mm, 0.5 mm pitch), thermally enhanced with exposed thermal pad; RoHS-compliant, automotive-grade molding compound.

Pin/Terminal	Circuit Role	Design Meaning
VBAT	Main power input	Primary 3.0–28 V supply rail; feeds internal regulators and high-voltage monitor circuitry.
VDDEXT	External 5 V output	Regulated 5 V supply for external Hall sensors; programmable enable/disable via SCU-PM register.
LIN	LIN bus I/O	Single-wire LIN physical layer interface with integrated transceiver and wake-up detection.
HS1	High-side switch output	Drives one side of DC motor; supports PWM up to 25 kHz with current sense feedback path.
LS1, LS2	Low-side switch outputs	Drive complementary motor terminals; support independent PWM control and short-circuit protection.
MON1–MON4	HV monitor inputs	Analog inputs for battery sense and motor phase voltage monitoring; routed to 10-bit ADC with programmable gain.
VBAT_SENSE	Battery voltage sense	Dedicated 8-bit ADC channel with internal scaling for accurate battery state-of-charge estimation.

Key Features

Feature	Design Value
LIN Bootstrap Loader (BSL)	Enables flash programming and firmware updates over LIN bus without debugger or external programmer - reduces EOL test complexity.
Cyclic Wake-up in Sleep Mode	Wakes MCU every 1–255 ms using internal RC oscillator - maintains LIN responsiveness while drawing <15 µA quiescent current.
Integrated Power Switch Protection	Real-time overcurrent detection, thermal foldback, and open-load diagnostics per switch - eliminates need for external sense resistors or protection ICs.
Dual ADC Architecture	Separate 8-bit (fast supervision) and 10-bit (precision control) ADC subsystems - allows concurrent battery health check and motor commutation timing without sampling conflict.
On-chip Temperature Sensor	Monitors die temperature with ±2°C accuracy across −40 °C to +125 °C - triggers automatic power derating before thermal shutdown.

Applications

Window Lift Control

Seat Position Adjustment

Use Scenario: Bidirectional DC motor driving automotive power window mechanism with anti-pinch detection.

IC Role / Device Role / Timing Role: Primary motor controller executing position-sensing algorithm, PWM gate timing, and LIN command interpretation.

Use Value: Integrated HS/LS switches and HV MON inputs reduce BOM count by 5 components versus discrete driver + MCU solution.

Use Scenario: Linear actuator control for electric seat fore/aft and recline functions with end-stop detection.

IC Role / Device Role / Timing Role: Real-time current monitoring and adaptive PWM duty cycle adjustment based on load torque feedback.

Use Value: On-chip 10-bit ADC channels directly sample motor current via shunt resistor, eliminating external signal conditioning.

Roof Panel Actuation

Trunk Lid Motor Control

Use Scenario: Controlled opening/closing of panoramic sunroof with obstacle detection and soft-stop behavior.

IC Role / Device Role / Timing Role: LIN slave node receiving position commands and reporting status; manages dual-switch H-bridge timing with dead-time control.

Use Value: Integrated LIN transceiver and BSL allow OEMs to perform field updates without disassembly or specialized tools.

Use Scenario: Power-assisted trunk lid lift with auto-hold and manual override detection.

IC Role / Device Role / Timing Role: Supervises battery voltage during high-current actuation and throttles PWM if VBAT drops below 9.5 V.

Use Value: Built-in VBAT_SENSE and 8-bit ADC provide accurate low-voltage warning without external divider network.

Equivalent & Alternatives

The following parts are listed as comparable options for similar automotive motor control applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
TLE9843QX	Includes second high-side switch (HS2); same pinout but different internal switch configuration.	Required for H-bridge topologies needing dual HS control (e.g., dual-motor seat systems).	Select when dual high-side drive is needed; not pin-compatible due to differing HS2 routing and thermal pad layout.
TLF35584ESV50	System basis chip (SBC) without MCU core; provides LIN, regulators, watchdog, but no flash/RAM or PWM peripherals.	Used as companion device alongside separate MCU - adds complexity vs. TLE9842QXXUMA2's SoC integration.	Choose only when existing MCU design requires supplemental power/LIN functionality; lacks motor control integration.

Compared with TLE9842QXXUMA2, TLE9843QX extends high-side drive capability at the cost of increased thermal dissipation, while TLF35584ESV50 offloads power management but forces external MCU selection and increases PCB area and interconnect latency.

FAQ

Is TLE9842QXXUMA2 qualified for automotive use?

Yes. The TLE9842QXXUMA2 is fully qualified to AEC-Q100 Grade-1 standards (−40 °C to +125 °C ambient), with validated reliability across temperature cycling, humidity testing, and ESD performance. It carries Infineon's automotive qualification certificate and is approved for safety-critical body electronics applications including power windows and seats.

Does it support firmware updates over LIN?

Yes. The device includes a LIN Bootstrap Loader (LIN BSL) that enables full flash memory programming and firmware updates via the integrated LIN transceiver - no JTAG debugger or external programmer required. The BSL supports secure authentication and CRC-protected data transfer per LIN 2.2A specification.

What is the maximum PWM frequency supported by its power switches?

The high-side and low-side switches support PWM operation up to 25 kHz, with configurable dead-time insertion (100 ns to 2 µs) managed by the CCU6 peripheral. This enables smooth motor commutation and acoustic noise reduction in 12 V DC motor applications such as window lift systems.

Can it operate directly from a car battery without external regulators?

Yes. The TLE9842QXXUMA2 accepts a single 3.0 V to 28 V supply on VBAT and internally generates all required voltages: 5.0 V (VDDP), 1.5 V (VDDC), and 5.0 V (VDDEXT). It tolerates cold-crank (down to 3.0 V) and load-dump transients (up to 40 V) without external protection components.
