Product details
Overview
TLE9833QXXUMA2 from Infineon Technologies is an automotive-qualified 8-bit microcontroller integrating LIN transceiver, dual high-side and dual low-side power switches, 44 kB Flash, XC800 core (40 MHz), and on-chip 1.5 V/5.0 V regulators - designed for body electronics control in 12 V vehicle systems such as seat motor drivers and window lift modules.
For engineers reviewing the TLE9833QXXUMA2 datasheet, TLE9833QXXUMA2 pinout, TLE9833QXXUMA2 application, or TLE9833QXXUMA2 equivalent, this device supports LIN 1.3/2.0/2.1 communication, embedded PWM generation via CCU6, hardware watchdog with windowed refresh, and direct drive of resistive/inductive loads up to 500 mA per switch - critical for functional safety–aware automotive subsystems.
Technical Context
The TLE9833QXXUMA2 implements a dual-voltage architecture: a 1.5 V core supply (VDDC) powers the XC800 CPU and digital logic, while a dedicated 5.0 V I/O supply (VDDP) drives GPIO, LIN transceiver, and switch drivers. Its integrated PMU includes loss-of-clock detection with automatic fail-safe shutdown of power switches.
Functional safety is supported through hardware features including a windowed watchdog timer (WDT), boot ROM with LIN BSL, and independent voltage monitors for VDDP, VDDC, and VBAT. The CCU6 unit provides complementary PWM outputs with dead-time insertion, enabling precise control of H-bridge motor drivers without external timing ICs.

Equivalent & Alternatives
The following parts are listed as comparable options for similar automotive microcontroller-with-integrated-power-switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLE9832QXXUMA2 | Same package and pinout; omits one high-side switch and one low-side switch (1HSS + 1LSS only) | Suitable for simpler actuators with single-direction drive or lower channel count | Select when BOM cost reduction is prioritized over redundancy or dual-motor support |
| TLE9842QXXUMA2 | Successor with upgraded XC800 core (up to 48 MHz), 64 kB Flash, CAN FD interface, and enhanced diagnostic coverage | Required for next-gen platforms needing CAN communication or higher ASIL compliance (ASIL-B ready) | Choose for new designs targeting extended lifecycle, CAN integration, or higher computational throughput |
Compared with TLE9832QXXUMA2, the TLE9833QXXUMA2 adds redundant switching capability for fail-operational seat systems; versus TLE9842QXXUMA2, it trades CAN FD and larger memory for lower cost and proven qualification in legacy 12 V body control units.

FAQ
What LIN protocol versions does the TLE9833QXXUMA2 support?
The TLE9833QXXUMA2 integrates a LIN transceiver compliant with LIN 1.3, LIN 2.0, and LIN 2.1 specifications per ISO 17987-4. It supports standard LIN frame formats, sleep/wake functionality, and bus fault tolerance up to ±40 V, enabling interoperability with legacy and modern LIN masters in automotive networks.
Does the TLE9833QXXUMA2 require external crystal or can it operate from internal RC oscillator?
The TLE9833QXXUMA2 requires an external crystal (1–20 MHz) on XTAL1/XTAL2 pins for reliable operation; its internal RC oscillator is not qualified for automotive use and lacks the stability needed for LIN baud rate accuracy. The PLL locks to the crystal to generate the 40 MHz system clock.
How are the high-side and low-side switches protected against overtemperature or overcurrent?
Each high-side and low-side switch includes integrated thermal shutdown and current-limit circuitry. Overcurrent detection triggers immediate current limiting (not latching), while die temperature exceeding 175°C disables the switch until cooldown. These protections are hardware-based and independent of firmware execution.
Can the TLE9833QXXUMA2 be programmed in-system via LIN without additional hardware?
Yes - the integrated LIN Bootstrap Loader (LIN BSL) enables full flash programming and verification over the LIN bus using standard LIN frames. No external debugger or programming header is required, provided the device is powered and the LIN bus is accessible with appropriate master node control.
