Infineon Technologies TLE9867QXA20XUMA1

Overview

TLE9867QXA20XUMA1 from Infineon is a single-chip automotive motor control solution integrating an Arm® Cortex®-M3 core (64 KB flash, 6 KB RAM), dual H-bridge MOSFET driver with charge pump, LIN 2.2 transceiver, and high-speed op-amp for shunt-based current sensing - all operating from a single 5.5–28 V supply across -40°C to +150°C junction temperature. It targets compact, cost-sensitive body electronics like window lift and tailgate actuators.

For engineers reviewing the TLE9867QXA20XUMA1 datasheet, TLE9867QXA20XUMA1 pinout, TLE9867QXA20XUMA1 application, or TLE9867QXA20XUMA1 equivalent, this device delivers integrated motor control logic, real-time current feedback, and LIN communication in one VQFN-48 package - eliminating external gate drivers, LIN transceivers, and discrete op-amps in 12 V automotive subsystems.

Technical Context

The TLE9867QXA20XUMA1 implements a tightly coupled system-on-chip architecture where the Cortex-M3 core directly controls the dual H-bridge driver via dedicated PWM outputs and monitors motor current through an internal 10 MHz op-amp feeding a 12-bit ADC. Its clock system combines an on-chip oscillator and PLL to generate precise timing for motor commutation and LIN baud rate generation.

Power management includes three regulated supplies: 5.0 V (VDDP) for digital logic and LIN transceiver, 1.5 V (VDDC) for the core, and an external 5.0 V (VDDEXT) option for high-current peripherals - all derived from the main battery input without requiring external regulators.

FAQ

Does TLE9867QXA20XUMA1 support CAN communication?

No. The TLE9867QXA20XUMA1 integrates only a LIN 2.2 transceiver and does not include CAN controller or physical layer. It is intended for lower-bandwidth body applications where LIN suffices - such as wipers, windows, and sunroofs - and must be paired with a separate CAN node if vehicle network integration is required.

What is the maximum continuous current each H-bridge can drive?

Each H-bridge supports 1.5 A continuous output current at T_j = 150°C with proper PCB thermal design (≥4 cm² copper pour under exposed pad). Peak current capability is 3.5 A for ≤10 ms pulses. Current limiting is implemented via internal comparators monitoring the shunt voltage, triggering automatic shutdown within 2 µs.

Can the internal op-amp be used for voltage sensing instead of current sensing?

Yes. The op-amp is configured as a unity-gain buffer in default mode but can be reconfigured via SCU registers for non-inverting or inverting gain stages. Its rail-to-rail input/output and 10 MHz bandwidth support battery voltage monitoring, potentiometer feedback, or other analog signal conditioning - though its primary validation is for shunt-based current sensing.

Is external crystal required for LIN communication?

No. The on-chip oscillator provides sufficient accuracy (±2 %) for LIN 2.2 baud rate generation in most applications. An external crystal (1–20 MHz) is optional and improves timing precision to ±0.5 % - recommended only for systems requiring strict LIN frame jitter control or synchronized multi-node timing.
