Selection Notes

Good for: reuse when package, electrical ratings, footprint, and assembly class match the project constraints
Avoid when: Not captured yet.
Known layout constraints: Verify package land pattern, decoupling requirements, thermal pad, RF keepouts, crystal routing, and boot straps from the datasheet.
Equivalent search hints: match category pwm-driver, interfaces i2c, pwm, package TSSOP-28, and EasyEDA footprint UUID ca390b72972f47dc8f86e88e3241ff4c.
