TLE98422QXXUMA2

Overview

The Infineon TLE9842-2QX is an automotive-grade microcontroller featuring a 32-bit Arm Cortex-M0 core with a clock frequency up to 40 MHz. It integrates 40 KB of flash memory (including emulated EEPROM), 2 KB of RAM, and a boot ROM. The device includes two high-side switches and two low-side switches with PWM capability, alongside an integrated LIN transceiver. Power management supports a single supply voltage from 3.0 V to 28 V, with an internal 5 V regulator for external loads. Measurement capabilities include an 8-bit ADC with 7 channels and a 10-bit ADC with 13 channels.

Feature Summary

• Arm Cortex-M0 core operating at up to 40 MHz
• Integrated power stage: 2 high-side and 2 low-side switches with PWM
• On-chip LIN transceiver with bootstrap loader support
• Dual ADC system: 8-bit (7 channels) and 10-bit (13 channels)

Applications

• Window lift systems

Procurement Notes

Verify the specific ordering suffix against the datasheet table to confirm package type (VQFN-48-31, -37, or -79) and step designation (AE or UD). Confirm that the selected variant matches the required pin configuration and marking scheme for the target application design.

Selection Notes

Select based on the required package footprint and manufacturing step. Ensure the 40 MHz core speed and 40 KB flash capacity meet the software requirements. Verify that the integrated high-side and low-side switch current ratings are sufficient for the connected load, such as window motors.

Part Context

This component belongs to the MOTIX™ family of microcontrollers designed for automotive applications. It combines MCU functionality with embedded power switches and communication interfaces, targeting simplified system designs for motor control and actuator applications in vehicles.

Replacement Considerations

Check for other variants within the TLE9842-2QX family that may offer different package options or steps. Cross-reference with similar MOTIX™ devices if higher integration or different switch configurations are needed.
