TLE9845QXXUMA1

Overview

The TLE9845QXXUMA1 is an automotive microcontroller featuring a 32-bit Arm Cortex-M0 core operating up to 40 MHz. It integrates 48 KB Flash (including EEPROM), 4 KB RAM, and 768 bytes of 100TP memory. The device includes two low-side switches with PWM capability, two high-side switches capable of supplying at least 150 mA, and a LIN 2.2 transceiver. Power management supports a single supply from 3.0 V to 28 V, generating internal 1.5 V and 5.0 V rails. It features a 10-bit ADC with multiple channels, measurement units, and various timers.

Feature Summary

Procurement Notes

Verify the specific ordering suffix for package type and tape/reel configuration against Infineon's official documentation. Confirm RoHS compliance status and AEC-Q100 qualification requirements for the target automotive application environment before procurement.

Selection Notes

Select this component for applications requiring integrated motor control or relay driving alongside LIN communication. Ensure the 48 KB Flash capacity meets firmware requirements. Verify that the 28 V maximum supply voltage aligns with the vehicle's electrical system specifications.

Part Context

This part belongs to the TLE984x family of microcontrollers designed for automotive embedded power applications. It shares architectural similarities with other members like the TLE9844 but offers distinct memory sizes and peripheral configurations tailored for specific actuator control tasks.

Replacement Considerations

Consult Infineon's official cross-reference tools for qualified replacements. Direct pin-to-pin substitutes within the same family may require firmware adaptation due to potential differences in peripheral mapping or memory allocation.
