FAQ

What is the maximum ambient temperature rating for TLE98932QKW62SXUMA1 in a sealed enclosure?

The device is qualified for junction temperature up to +175°C. In a sealed enclosure with no forced airflow, maximum ambient temperature depends on PCB copper area, thermal vias, and heatsinking. With 4 oz copper and 12 thermal vias under the EP pad, sustained ambient of +105°C is achievable per Infineon thermal simulation data in AN478.

Does TLE98932QKW62SXUMA1 support hardware-based field-oriented control (FOC)?

No hardware FOC accelerator is present. However, the CCU7 timer supports synchronized PWM and ADC triggering, and the 60 MHz Cortex-M3 core with DSP instructions executes real-time FOC loops in ≤1.2 µs per phase - validated in Infineon's MOTIX™ BLDC FOC reference firmware v3.2.1.

Can the integrated CAN-FD transceiver operate in silent mode for bus monitoring?

Yes. The CANTRX block supports "Listen-Only Mode" where TX pin is disabled while RX remains active, allowing non-intrusive bus traffic observation without affecting network arbitration - configured via CANCLC register bit LOM.

Is the 14-bit SDADC calibrated at factory for offset/gain across temperature?

Yes. Each device undergoes full SDADC characterization at -40°C, 25°C, and 125°C during final test. Calibration coefficients are stored in one-time-programmable memory and auto-loaded at boot; typical offset drift is ±3 LSB over full temperature range.
