Infineon Technologies TLE9867QXA20XUMA2

Overview

TLE9867QXA20XUMA2 from Infineon is a single-chip automotive MCU integrating an Arm® Cortex®-M3 core, LIN 2.2 transceiver, and H-bridge MOSFET driver for brush DC motor control. It delivers 64 KB flash, 6 KB RAM, operates from 5.5 V to 28 V, supports -40°C to +150°C junction temperature, and includes a high-speed op-amp for shunt-based current sensing - enabling compact wiper and window lift actuation.

For engineers reviewing the TLE9867QXA20XUMA2 datasheet, TLE9867QXA20XUMA2 pinout, TLE9867QXA20XUMA2 application, or TLE9867QXA20XUMA2 equivalent, key selection criteria include integrated LIN physical layer compliance, on-die charge pump for N-channel H-bridge gate drive, and AEC-Q100 qualification for under-hood motor control.

Technical Context

The TLE9867QXA20XUMA2 implements a tightly coupled system-on-chip architecture where the Cortex-M3 core executes motor control algorithms while sharing memory and peripherals with dedicated analog and power modules. Its SCU-PM block manages power sequencing, voltage regulation (VDDP = 5.0 V, VDDC = 1.5 V), and thermal monitoring.

Timing is derived from dual clock sources: a low-precision internal oscillator and a high-precision external crystal or input clock feeding the PLL. The CCU6 unit provides advanced PWM generation with dead-time insertion and fault protection, directly synchronized to the H-bridge driver stage.

FAQ

Does TLE9867QXA20XUMA2 support CAN communication?

No. The TLE9867QXA20XUMA2 integrates only a LIN 2.2 transceiver and does not include CAN or CAN FD capability. Its communication interface is strictly single-wire LIN for slave-node applications such as wipers and window lifts. CAN support begins with higher-tier MOTIX devices like the TLE9879 series.

What external components are required for basic H-bridge operation?

For H-bridge operation, four external N-channel MOSFETs, two bootstrap capacitors (one per high-side switch), a shunt resistor for current sensing, and decoupling capacitors on VBAT, VDDP, and VDDC are mandatory. No external gate drivers or LIN transceivers are needed due to full on-die integration.

Is the on-chip oscillator sufficient for LIN timing accuracy?

Yes. The high-precision oscillator (OSC_HP) supports external crystal or clock input modes, achieving ±1.5% LIN baud rate accuracy over temperature and voltage - meeting LIN 2.2 specification requirements without trimming or calibration.

How is thermal protection implemented?

Thermal protection uses an on-die temperature sensor monitored by the SCU-PM block. When junction temperature exceeds +150°C, the device asserts INH low, disabling all drivers and regulators. Recovery occurs automatically after temperature falls below +140°C hysteresis, with no firmware intervention required.
