TLE98422QXXUMA1

Overview

The Infineon TLE9842-2QX is an automotive-grade microcontroller featuring a 32-bit ARM Cortex-M0 core with a maximum clock frequency of 40 MHz. It integrates 40 KB of flash memory (including emulated EEPROM), 2 KB of RAM, and 768 bytes of 100TP. The device includes an integrated LIN transceiver, two high-side switches, and two low-side switches with PWM capability. Power supply ranges from 3.0 V to 28 V, supporting an external 5 V regulator. It features a measurement unit with 8-bit and 10-bit ADCs, GPIO ports, and multiple timer units.

Feature Summary

• ARM Cortex-M0 core operating up to 40 MHz
• Integrated LIN transceiver with bootstrap loader
• Dual high-side and dual low-side power switches with PWM
• Measurement unit with 10-bit ADC (13 channels) and 8-bit ADC (7 channels)

Applications

• Window lift systems

Procurement Notes

Verify the specific package variant (VQFN-48-31, -37, or -79) against design requirements, as availability varies by step. Confirm AEC-Q100 qualification status for the target automotive application environment. Ensure compatibility with existing LIN network protocols and voltage levels.

Selection Notes

Select based on required switch configurations; note that HS2 availability depends on the specific product variant. Evaluate thermal resistance for the chosen package type under expected load conditions. Check if the 40 MHz core speed meets processing demands compared to lower-frequency variants in the family.

Part Context

This component belongs to the MOTIX™ TLE984x series of motor control SoCs designed for brushed DC motor applications. It is part of Infineon's portfolio for compact automotive solutions, specifically targeting window lift modules where integrated power switching and communication are required.
