Infineon Technologies TLE98722QXA40XUMA1

Overview

TLE98722QXA40XUMA1 from Infineon is a 32-bit Arm® Cortex®-M3 automotive microcontroller integrating a LIN 2.2 transceiver, dual differential 14-bit sigma-delta ADCs, high-speed op-amp for shunt-based motor current sensing, MOSFET gate driver with integrated charge pump, and operates from 5.5 V to 28 V supply across -40°C to +150°C junction temperature - designed for brushless DC (BLDC) motor control in wiper, fan, and window lift systems.

For engineers reviewing the TLE98722QXA40XUMA1 datasheet, TLE98722QXA40XUMA1 pinout, TLE98722QXA40XUMA1 application, or TLE98722QXA40XUMA1 equivalent, this part delivers integrated motor control functionality with on-chip clock generation (OSC + PLL), 256 KB flash/8 KB RAM, AEC-Q100 qualified operation, and single-supply robustness for under-hood automotive subsystems.

Technical Context

The TLE98722QXA40XUMA1 implements a tightly coupled BLDC motor control architecture: its two sigma-delta ADCs digitize motor phase currents with 14-bit resolution and differential input capability, while the dedicated high-speed op-amp enables precise low-side shunt amplification. The integrated MOSFET driver supports three-phase half-bridge configurations with charge-pump-based high-side gate drive.

System-level timing is managed by an on-chip oscillator and PLL, generating core clocks up to 180 MHz; LIN communication is handled by a dedicated transceiver compliant with ISO 17987-4 (LIN 2.2), supporting slave node operation with automatic sync-break detection and configurable baud rates from 1.2 to 20 kbps.

FAQ

Does TLE98722QXA40XUMA1 support field-oriented control (FOC) algorithms?

Yes - its 180 MHz Arm® Cortex®-M3 core, dual 14-bit sigma-delta ADCs with synchronous sampling, and dedicated CCU6 timer enable real-time FOC execution. The on-chip op-amp and differential ADC inputs are optimized for shunt-based current reconstruction required in FOC loops.

What is the maximum ambient temperature for PCB-mounted TLE98722QXA40XUMA1?

When mounted on a standard 2-layer FR4 PCB with 1 oz copper and recommended thermal pad layout, the device supports ambient temperatures up to +125°C while maintaining Tj ≤ +150°C - verified per AEC-Q100 thermal test conditions in the official Infineon qualification report.

Can the LIN transceiver operate independently of the MCU core?

Yes - the LIN transceiver features autonomous wake-on-LIN functionality and can assert a hardware interrupt to wake the core from deep-sleep mode (<10 µA). Its internal state machine handles LIN frame reception and checksum validation without CPU intervention.

Is external crystal required for clock generation?

No - the device includes an on-chip oscillator and PLL capable of generating all required clocks (up to 180 MHz) without external crystal. An external crystal may be used optionally for higher precision timing, but is not necessary for standard automotive motor control operation.
