Procurement Notes

Verify the specific suffix 'UMA3' against official Infineon documentation to confirm package type (VQFN-48-22 or VQFN-48-29) and temperature range specifications. Ensure that the ordering information matches the exact device configuration required for the target application, as variations exist within the TLE983x family regarding peripheral availability and memory size.

Selection Notes

Select this component when an automotive-grade MCU with integrated power switches and LIN communication is required. The TLE9832 supports a wide input voltage range of 3.0 V to 27 V, making it suitable for 12 V and 24 V automotive networks. Consider the available GPIO count and ADC channels if analog sensing or high-voltage monitoring inputs are necessary for the system design.

Part Context

The TLE9832 belongs to the TLE983x product family designed for cost-effective automotive solutions. It shares the XC800 core architecture with other devices in the series but differs in peripheral configurations and memory sizes. The QXX suffix indicates the package variant, while UMA3 denotes the specific reel packaging and tape-and-reel format for automated assembly.

Replacement Considerations

Direct replacements within the TLE983x family must be verified against Table 1 in the datasheet for matching Flash size, switch counts, and monitor inputs. Cross-family migration requires re-evaluation of pin compatibility and software libraries due to potential differences in register maps and peripheral implementations.
