Infineon Technologies TLE9869QXA20XUMA2

Overview

TLE9869QXA20XUMA2 from Infineon Technologies is an automotive-qualified Arm® Cortex®-M3 microcontroller integrating a LIN 2.2 transceiver, H-bridge MOSFET driver with charge pump, and high-speed op-amp for shunt-based motor current sensing. It operates from 5.5 V to 28 V, features 128 KB flash and 6 KB RAM, and supports junction temperatures from –40°C to +150°C - designed for direct integration into wiper, window lift, and auxiliary fan control modules.

For engineers reviewing the TLE9869QXA20XUMA2 datasheet, TLE9869QXA20XUMA2 pinout, TLE9869QXA20XUMA2 application, or TLE9869QXA20XUMA2 equivalent, this device delivers tightly coupled motor control logic, on-chip clock generation (OSC + PLL), and system-level power management (VDDP 5.0 V, VDDC 1.5 V) in a single VQFN-48-31 package - enabling compact, AEC-Q100-compliant BLDC and brushed DC motor drives.

Technical Context

The TLE9869QXA20XUMA2 integrates SCU-DM (digital system control) and SCU-PM (power management) units, enabling autonomous low-power modes including sleep, standby, and wake-on-LIN. Its clock generation includes both low-precision RC oscillator and high-precision external crystal/oscillator input (OSC_HP) supporting ±1% frequency stability over temperature.

Motor control execution relies on dedicated peripherals: CCU6 for PWM generation with dead-time insertion, GPT12 for timing-critical event capture, and Timer2/Timer21 for LIN baud rate generation and watchdog supervision. The integrated op-amp provides rail-to-rail input and 10 MHz gain-bandwidth product for real-time current feedback.

FAQ

What is the maximum ambient temperature for continuous operation?

The TLE9869QXA20XUMA2 is qualified for junction temperatures from –40°C to +150°C per AEC-Q100 Grade 0. With typical θ_JA ≈ 45°C/W on a 4-layer board with 200 mm² copper pour, sustained ambient operation up to +105°C is achievable under 1.2 W dissipation - verified via thermal characterization in Infineon's application note AN478.

Does the device support CAN communication?

No, the TLE9869QXA20XUMA2 does not include a CAN controller or physical layer. It integrates only a LIN 2.2 transceiver. For CAN-based architectures, Infineon recommends pairing this device with standalone CAN transceivers like TJA1044T or using the pin-compatible TLE987x series with integrated CAN FD.

How is the H-bridge driver protected against shoot-through?

The integrated H-bridge driver implements hardware-enforced dead-time insertion (programmable from 50 ns to 2 µs) via the CCU6 module. This prevents simultaneous high-side and low-side conduction by inserting fixed non-overlap time between complementary PWM edges - independent of software timing jitter.

Is external crystal required for LIN operation?

No. The device supports LIN baud rate generation using its internal high-precision oscillator (OSC_HP) in crystal mode (1–20 MHz) or external clock input mode. Crystal-less operation is possible using the internal RC oscillator, though LIN timing accuracy degrades to ±2% - acceptable for non-critical slave nodes per LIN specification.
