Procurement Notes
Verify the specific suffix 'GR' against official MPS documentation to confirm pinout and thermal characteristics. Ensure the component meets AEC-Q100 grade requirements for your target automotive environment. Cross-reference the datasheet revision date to validate parameter accuracy before integration into production designs.
Selection Notes
Select this component when sixteen individually controllable channels are required within a compact footprint. The wide input voltage range accommodates various automotive power supply conditions. Consider the thermal dissipation capabilities relative to the PCB layout and ambient operating temperature constraints.
Part Context
This part belongs to the MPQ3326 family of multi-channel LED drivers designed for automotive use. It complements other MPS PMIC solutions by providing dedicated high-density channel control. The series emphasizes reliability and flexibility for complex lighting architectures in modern vehicles.
Replacement Considerations
Check MPS documentation for direct substitutes such as the MPQ3326AGRE-AEC1-Z, noting differences in output current ratings and package variations. Verify compatibility with existing board layouts and control signals before substitution.
