Product details
Overview
TLE9853QXXUMA1 from Infineon Technologies is an automotive-qualified 32-bit Arm® Cortex®-M0 microcontroller integrating LIN 2.2 transceiver, adaptive H-bridge NFET driver, current sense amplifier, high-side switch (≥150 mA), and dual ADC subsystems (10-bit + 8-bit) for motor control. It operates from 3 V to 28 V supply, supports -40°C to +150°C junction temperature, and targets single-phase DC/BLDC motor applications including window lift and HVAC blower.
For engineers reviewing the TLE9853QXXUMA1 datasheet, TLE9853QXXUMA1 pinout, TLE9853QXXUMA1 application, or TLE9853QXXUMA1 equivalent, key selection criteria include integrated LIN compliance, adaptive gate drive tuning for EME/power trade-off, cyclic wake-up capability in Sleep Mode, and AEC-Q100 qualification with on-chip voltage supervision across 12 analog channels.
Technical Context
The TLE9853QXXUMA1 implements a tightly coupled system-on-chip architecture where the Arm Cortex-M0 core (40 MHz, single-cycle multiplier) directly controls motor timing via CCU6 capture/compare units and GPT12/Timer2/Timer21 peripherals. Its adaptive MOSFET driver dynamically adjusts gate current to compensate for MOSFET parameter spread, enabling simultaneous optimization of electromagnetic emissions and power dissipation.
Two independent ADC subsystems serve distinct monitoring roles: the 10-bit converter handles 5 analog inputs plus VBAT_SENSE, VS, and 4 high-voltage monitor pins (direct battery-connected), while the 8-bit unit supervises 9 voltage/temperature channels. All analog inputs feed into a shared 12-channel measurement unit with on-chip post-processing.
Key Specifications

|---|---|
| CPU Core | Arm Cortex-M0 @ 40 MHz, one clock per machine cycle, enabling deterministic real-time motor control loops. |
| Memory | 48 KB Flash (with emulated 4 KB EEPROM) + 4 KB RAM + 512 B 100TP memory for calibration data storage. |
| ADC System | Dual converters: 10-bit (12-channel measurement unit) + 8-bit (9-input supervision), eliminating external signal conditioning for battery and temperature monitoring. |
| MOSFET Driver | Adaptive H-bridge NFET driver with automatic gate current adjustment to maintain consistent switching times across MOSFET parameter variation. |

| Integrated LIN Transceiver | Meets LIN 2.2 specification with slew-rate control and bus fault protection, eliminating need for external transceiver IC in cost-sensitive nodes. |
| Dual ADC Architecture | 10-bit ADC handles precision motor control feedback (e.g., current sensing), while 8-bit ADC monitors safety-critical parameters like die temperature and supply rails. |
| Math Co-Processor Unit | Dedicated divider unit accelerates signed/unsigned 32-bit division-critical for real-time torque calculation and field-oriented control algorithms. |

FAQ
What is the maximum operating junction temperature for TLE9853QXXUMA1?
The TLE9853QXXUMA1 is qualified for operation from -40°C to +150°C junction temperature per AEC-Q100 Grade 1 requirements. This rating enables deployment in passenger compartment locations such as door modules and HVAC housings, but excludes direct engine bay mounting where higher-grade variants like TLE9863 are specified.
Does TLE9853QXXUMA1 support sensorless BLDC commutation?
Yes-the device supports sensorless commutation through its 10-bit ADC with dedicated inputs for back-EMF sampling, combined with CCU6 timer units for precise PWM generation and dead-time insertion. The integrated current sense amplifier further enables torque-controlled operation without external shunt amplifiers.
Can the high-voltage monitor inputs (ADCHV1–ADCHV4) be used without external resistive dividers?
Yes-these pins accept direct connection to battery voltage (up to 28 V) due to internal scaling and clamping circuitry. Each input supports both cyclic sense wake-up and analog measurement, eliminating external voltage dividers and reducing BOM cost and PCB area in battery-supervised applications.
Is the TLE9853QXXUMA1 pin-compatible with other TLE985x devices?
Yes-all TLE985x variants (including TLE9853, TLE9854, and TLE9855) share identical VQFN-48-31 pinout and electrical characteristics for common signals. Software is also compatible across the family, enabling hardware reuse and scalable design migration based on Flash size or temperature grade requirements.
