Procurement Notes
Verify the specific suffix (e.g., GU) against official Microchip documentation to confirm package type and tape/reel specifications. Confirm current manufacturing status as some variants may be obsolete. Ensure compatibility with system voltage requirements (4.75V-5.5V) and thermal constraints (-40°C to 85°C). Cross-reference pinouts with the latest datasheet before PCB layout finalization.
Selection Notes
Select this component when a multi-channel LED driver with linear PWM dimming is required. It is suitable for applications needing 16 outputs with 30mA per channel. Consider the 32-SOP package size for space-constrained designs. Verify that the input voltage range matches the system power supply. Check for alternative packages if lead-free or specific reel options are needed.
Part Context
The MSL3167GU belongs to Microchip's PMIC - LED Drivers catalog. It is part of a family of components designed for efficient LED management. Similar parts may offer different channel counts or dimming methods. The GU suffix typically denotes a specific package variant. Consult the full datasheet for detailed electrical characteristics and application circuits.
Replacement Considerations
Check Microchip's official substitution guide for direct replacements. Note that the MSL3167GU-R variant exists but may have different packaging. Verify pin-to-pin compatibility and electrical parameters before substituting. Ensure the replacement supports the same 16-channel linear PWM dimming requirement.
