UCD3138RJA
(40 QFN)
NOTE: The RJA package has thicker package height compared to the RMH package. There are also four corner pins on the RJA
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.
