TLE6232GPNUMA1

Overview

The TLE6232GPNUMA1 is a smart six-channel low-side power switch manufactured by Infineon Technologies. It integrates six N-channel outputs within a PG-DSO-36 package, designed for automotive applications requiring robust load driving capabilities. The device operates with an input voltage range of 4.5 V to 5.5 V and supports individual channel currents up to 1.1 A, with peak hold capabilities reaching 550 mA under specific conditions. Key electrical parameters include a maximum on-resistance of 450 mOhms per channel and a total power dissipation rating of 3.3 W. It features SPI interface control and functions across a junction temperature range of -40°C to +150°C.

Feature Summary

• Integrates six independent low-side switches with dedicated diagnostic feedback via SPI interface
• Provides comprehensive protection mechanisms including overcurrent limiting, thermal shutdown, and open-load detection
• Features high-reliability construction suitable for harsh automotive environments with extended operating temperature ranges

Applications

• Automotive lighting systems such as headlamps and interior illumination
• Actuator control for valves and motors in vehicle chassis systems
• General purpose load switching in automotive electronic control units

Procurement Notes

Verify the exact ordering suffix to confirm package type and tape/reel specifications. Ensure compatibility with existing PCB footprints for the PG-DSO-36 housing. Confirm that the selected variant meets the required AEC-Q100 qualification standards for your specific automotive application tier. Cross-reference the datasheet revision to ensure all functional blocks align with system design requirements.

Selection Notes

Select this component when designing circuits requiring multiple isolated low-side outputs controlled via a serial interface. Consider the thermal management requirements given the 3.3 W total dissipation limit and the 450 mOhm on-resistance. Evaluate the need for diagnostic features like open-load detection if fault reporting is critical. Ensure the supply voltage remains within the 4.5 V to 5.5 V window for reliable operation.

Part Context

This part belongs to the TLE6232 series of smart power switches from Infineon. The series is characterized by its multi-channel architecture and integrated diagnostics. Variants within the family may differ in package options or specific current ratings, but share the core functionality of intelligent low-side switching for automotive loads.

Replacement Considerations

Direct substitutes include other variants within the TLE6232 family such as TLE6232GPAUMA2 or TLE6232GPXT, provided they match the pinout and electrical characteristics. Verify that any replacement maintains the same SPI communication protocol and diagnostic feedback structure.
