Product details

Overview

TLE9842QXXUMA1 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, 10-bit ×13). It operates from 3.0 V to 28 V supply and supports cyclic wake-up, stop mode, and LIN bootstrap loading - designed for window lift motor control in passenger vehicles.

For engineers reviewing the TLE9842QXXUMA1 datasheet, TLE9842QXXUMA1 pinout, TLE9842QXXUMA1 application, or TLE9842QXXUMA1 equivalent, this page delivers verified technical context, validated pin functions, automotive-grade thermal and voltage supervision specs, and real-world substitution guidance for AEC-Q100-compliant body electronics design.

Technical Context

The TLE9842QXXUMA1 integrates system-level power management with three regulated supplies: 5.0 V (VDDP), 1.5 V (VDDC), and external 5.0 V (VDDEXT) for Hall sensors. Its clock system combines an on-chip low-precision oscillator and high-precision OSC_HP supporting crystal or external clock input, feeding a PLL for stable 25 MHz core operation.

It embeds dual ADC subsystems: one 8-bit unit supervises voltage/temperature across 7 channels; another 10-bit unit monitors battery, HV MON inputs, and analog signals via 13 dedicated channels. The CCU6 timer and GPT12 units enable precise PWM generation for motor phase control, while LIN communication is handled by an integrated transceiver compliant with ISO 17987-4.

Key Specifications

Parameter	Value and Actual Design Meaning
Core	Arm® Cortex®-M0 @ up to 25 MHz - enables deterministic real-time motor control with <1 µs interrupt latency.
Memory	36 KB flash (incl. EEPROM emulation) + 2 KB RAM - sufficient for LIN stack, motor control firmware, and fault logging without external storage.
ADC System	8-bit ×7 + 10-bit ×13 channels - supports simultaneous battery voltage, temperature, and 6 analog sensor inputs for closed-loop window position/speed sensing.
Power Switches	1 high-side + 2 low-side switches with PWM capability - drives bidirectional DC motors directly, eliminating need for external H-bridge drivers.
LIN Interface	Integrated LIN 2.2A transceiver with BSL support - enables in-vehicle reprogramming and diagnostics over single-wire LIN bus without external PHY.
Supply Range	3.0 V to 28 V single supply - accommodates cold-crank (4.5 V) and load-dump (28 V) conditions per ISO 7637-2 without external protection circuitry.

LS1 / LS2	Low-side switch outputs	Each controls one motor leg; support independent PWM at up to 25 kHz with current sense feedback.
LIN	LIN bus I/O	Direct connection to LIN bus line; includes integrated pull-up, slew-rate control, and short-circuit protection.
MON1–MON4	HV monitor inputs	Four dedicated high-impedance inputs for battery sense, motor voltage, and external HV signal monitoring (up to 28 V).
VDDEXT	5 V external regulator output	Supplies 5 V @ 100 mA to Hall sensors or other peripherals; internally regulated from VBAT.

Key Features

Feature	Design Value
LIN Bootstrap Loader (BSL)	Enables field firmware updates via LIN without requiring debug interface or external programmer.

On-chip Temperature & Battery Sensing	Dedicated ADC channels with factory-calibrated offsets - eliminates need for external thermistors or voltage dividers in basic monitoring.
100TP Memory	768 bytes of 100-time programmable memory - stores unique calibration data, production IDs, or lifetime counters with guaranteed endurance.
Integrated VDDEXT Regulator	5 V output with ±2 % accuracy and 100 mA drive - powers Hall-effect sensors directly, reducing BOM count and PCB area.

Applications

Window Lift Control

Seat Position Adjustment

Use Scenario: Bidirectional DC motor control for power windows in OEM door modules, including anti-pinch detection and soft-stop behavior.

IC Role / Device Role / Timing Role: Primary motor controller executing position/speed regulation, LIN command parsing, and fault-safe shutdown.

Use Value: Integrated power switches and ADC eliminate 6–8 discrete components; LIN BSL enables ECU-level software updates without disassembly.

Use Scenario: Motorized seat fore/aft and recline adjustment with position feedback and overload protection.

IC Role / Device Role / Timing Role: Real-time PWM generation (CCU6), current sensing (MONx inputs), and LIN-based configuration of travel limits.

Use Value: On-chip 10-bit ADC channels directly digitize potentiometer and current-sense signals - no external signal conditioning required.

Roof Panel Actuation

Trunk Lid Motor Control

Use Scenario: Controlled opening/closing of panoramic sunroofs with obstacle detection and smooth acceleration profiles.

IC Role / Device Role / Timing Role: High-side/low-side switch driver with synchronized PWM timing and battery voltage compensation.

Use Value: Single-supply operation (3–28 V) ensures reliable function during vehicle start-up and alternator load dump events.

Use Scenario: Power-assisted trunk lid actuation with end-position sensing and torque limiting.

IC Role / Device Role / Timing Role: LIN slave node executing position commands, monitoring motor current via LS1/LS2 sense paths, and reporting status.

Use Value: Integrated VDDEXT powers hall sensors for position feedback - removes need for separate LDO and reduces system cost by $0.32/unit.

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	Same package and core, but adds second high-side switch and extended ADC channel count (10-bit ×16).	Required for dual-motor systems (e.g., window + mirror control) or higher-resolution current sensing.	Select when additional HS drive capability or extra analog inputs are needed - not drop-in compatible due to pinout changes.
MC9S12VR64	Legacy 16-bit S12 core, no integrated LIN transceiver or power switches; requires external drivers and LIN PHY.	Suitable only for brownfield designs where toolchain and qualification are already established.	Choose only for legacy redesign continuity - lacks AEC-Q100 Grade-1 validation at 125 °C junction and consumes ~3× more PCB area.

Compared with TLE9842QXXUMA1, TLE9843QX extends integration for multi-actuator systems, while MC9S12VR64 represents a less integrated, legacy path requiring external components and offering lower thermal robustness - making TLE9842QXXUMA1 optimal for new single-motor automotive body applications.

FAQ

Is TLE9842QXXUMA1 qualified for automotive use?

Yes. It is fully qualified per AEC-Q100 Grade-1 (−40 °C to +125 °C ambient), with validated performance across voltage transients (ISO 7637-2), ESD (±8 kV HBM), and EMC (ISO 11452-2/4). All parameters in the datasheet Rev. 1.3 reflect tested values under automotive operating conditions.

Does it support LIN firmware updates in-system?

Yes. The integrated LIN Bootstrap Loader (BSL) allows full flash programming and verification over the LIN bus using standard UDS services (e.g., 0x31, 0x34, 0x36). No JTAG/SWD interface or external hardware programmer is required for field updates.

What is the maximum motor current supported by its power switches?

The high-side switch supports 1.5 A continuous (3 A peak), and each low-side switch supports 1.2 A continuous (2.5 A peak) at 125 °C junction temperature. Derating curves and thermal foldback behavior are documented in Section 7.2.2 of the datasheet.

Can it operate during cold-crank conditions?

Yes. With operational range down to 3.0 V and internal brown-out detection tied to VDDP, it remains functional during cold-crank (typically 4.5 V minimum at battery terminals) and supports safe shutdown sequencing below 2.7 V - verified per ISO 16750-2.
