Product details
Overview
TLE9852QXXUMA1 from Infineon Technologies is a 32-bit Arm® Cortex®-M0 automotive microcontroller integrating LIN 2.2 transceiver, adaptive H-bridge NFET driver, and dual ADC subsystems (10-bit + 8-bit) for motor control. It operates from 3 V to 28 V supply, features 48 KB Flash (with emulated 4 KB EEPROM), 4 KB RAM, and supports -40°C to +150°C junction temperature - deployed in window lift modules requiring integrated power, communication, and sensing.
For engineers reviewing the TLE9852QXXUMA1 datasheet, TLE9852QXXUMA1 pinout, TLE9852QXXUMA1 application, or TLE9852QXXUMA1 equivalent, key selection criteria include its adaptive MOSFET gate drive algorithm, cyclic sense wake-up capability across 4 HV monitor inputs, LIN-compliant UART1, and AEC-Q100 qualification for under-hood motor control systems.
Technical Context
The device implements a single-cycle 40 MHz Arm Cortex-M0 core with integrated math co-processor (32-bit signed/unsigned divider) and boot ROM for Flash programming. Its SCU-PM unit delivers three LDOs: 1.5 V core (VDDC), 5.0 V internal (VDDP), and 5.0 V external (VDDEXT) for Hall sensors.
Power management includes programmable window watchdog (WDT1) with independent clock, brownout detection, overtemperature shutdown, and short-circuit protection on all regulators and high-side switch. Sleep/Stop modes support cyclic sense wake-up via GPIO or HV inputs - critical for battery-conscious automotive body electronics.

FAQ
What LIN protocol versions does the TLE9852QXXUMA1 support?
The device integrates a hardware LIN 2.2 transceiver compliant with ISO 17987-4. It supports standard LIN frame formats, auto-baud detection, sleep/wake functionality, and error handling per LIN specification - no external transceiver required. Firmware-level LIN stack implementation is handled via Infineon's DAVE™ or AUTOSAR-compliant drivers.
Does the TLE9852QXXUMA1 require external components for HV input monitoring?
No. The four HV1–HV4 pins accept 0–28 V directly and include internal scaling and protection circuitry. They support both analog measurement (10-bit ADC) and digital wake-up sensing - eliminating external voltage dividers, level shifters, or protection diodes typically needed for battery-sensed inputs.
How does the adaptive MOSFET driver improve system performance?
The driver dynamically adjusts gate current based on measured MOSFET switching times to maintain target slew rates. This simultaneously reduces electromagnetic emissions (EME) through controlled edge rates and minimizes conduction losses by optimizing dead time - verified across temperature and MOSFET lot variations in Infineon's validation reports.
Is the TLE9852QXXUMA1 pin-compatible with other TLE985x variants?
Yes. All TLE985x devices (TLE9851/52/53/54) share identical VQFN-48-31 pinout and electrical characteristics. Firmware and hardware designs are interchangeable within the family - only Flash size, EEPROM capacity, and temperature grade differ between variants.
