Overview
The TLE6244XAQMA1 is a power switch and driver manufactured by Infineon Technologies, designed for automotive applications. It features an SPI interface and operates within a load voltage range of 4.5V to 5.5V. The device provides 18 low-side N-channel outputs with a 1:1 input-to-output ratio. It is housed in a PG-MQFP-64-10 package (64-BQFP with exposed pad) and supports surface mount installation. The component includes fault protection mechanisms such as overtemperature and overvoltage protection, functioning reliably across a junction temperature range of -40°C to 150°C.
Feature Summary
- Integrates 18 low-side N-channel power switches controlled via a serial peripheral interface.
- Includes hardware-based fault protection against overtemperature and overvoltage conditions.
- Designed for robust operation in high-temperature automotive environments.
Applications
- Automotive lighting systems
- General purpose load switching in vehicle electronics
- Power distribution units
Procurement Notes
Verify the exact suffix configuration, as the requested model TLE6244XAQMA1 differs from the documented TLE6244XAUMA1. Confirm availability status, as the referenced datasheet indicates the TLE6244X series may be discontinued. Ensure the specific AEC-Q100 qualification and packaging variant match the design requirements before procurement.
Selection Notes
Select this component when a high-density array of individually addressable low-side switches is required. The integrated SPI interface reduces pin count compared to parallel control solutions. Consider the thermal performance of the exposed pad package for heat dissipation in confined spaces. Verify that the 5.5V maximum load voltage aligns with the target system supply rails.
Part Context
This part belongs to the TLE6244X family of smart power switches. These devices are engineered for automotive reliability, combining power output stages with diagnostic and control logic. The family typically offers multiple channel counts and interface options to suit various electronic control unit architectures.
Replacement Considerations
Publicly confirmed substitute part numbers for TLE6244XAQMA1 were not found in the provided documentation. Cross-reference with other members of the TLE6244X family or consult manufacturer guidelines for direct replacements.
