Procurement Notes

Verify the specific suffix 'UMA1' against Infineon's official ordering list to confirm package type (VQFN-48-22 or VQFN-48-29) and tape/reel specifications. Ensure compatibility with required development tools such as C compilers and emulators for the XC800 architecture.

Selection Notes

Select this component for applications requiring tight integration of MCU, LIN communication, and high-voltage switching in a single package. Consider the 36 kByte Flash size and available GPIOs for system complexity. Verify thermal requirements given the VQFN package options and automotive temperature range of -40 °C to 150 °C.

Part Context

The TLE9832 belongs to the TLE983x family, which offers varying peripheral configurations and memory sizes. This specific model provides 36 kByte Flash, one High Side Switch, and five High Voltage Monitor inputs. It is designed for cost-effective solutions in automotive environments where space and component count are critical constraints.

Replacement Considerations

Check Infineon's official documentation for direct pin-to-pin replacements within the TLE983x family, such as TLE9832QV or TLE9832QX, depending on the required package variant. No other cross-model substitutes are confirmed in the provided datasheet.
