2.8 UCD3138RMH 40 QFN With Corner Anchors – Pin Assignments
NOTE: The RMH package has thinner package height compared to the RHA package. There are also four corner
pins on the RMH package. These features help to improve solder-joint reliability. The corner anchor pins and thermal
pad should be soldered for robust mechanical performance and should be tied to the appropriate ground signal.
