5 Revision History

NOTE: Page numbers for previous revisions may differ from page numbers in the current version.

Changes from Revision C (March 2017) to Revision D (April 2021)

Page

• Add 40 pin RJA Package option (global). Change sync feature description to say it works with all UCD3138

family members instead of just UCD3138064. Split Device Overview section into 4 sections to conform to TI

data sheet standards. ........................................................................................................................................ 1

• Add RJA Package to Device Information table. Change number of ADC channels from 14 to 15, because

channels 0 to 13 are for external pins, and channel 14 is for the internal temperature sensor.......................... 2

• Add RJA package for new designs note ............................................................................................................2

• Added RJA to top line, deleted empty column, deleted row with External Crystal Clock Support, since only

UCD3138128A supports it ................................................................................................................................. 6

• Add RJA Package top view, as well as notes about corner pad soldering and reliability for both RMH and RJA

packages............................................................................................................................................................ 8

• Add DAC Output as an alternate pin assignment for pins 2, 3, and 4 on the 40 pin QFN package table.

Change package descriptions in tables for clarity and consistency....................................................................9

• Add reference to IC Package Thermal Metrics application report in thermal table ..........................................13

• Add RJA package to thermal table .................................................................................................................. 13

• Fixed cross reference for current share resistor and current source ............................................................... 14

• Rise and fall time descriptions were switched to make them match the data. Before the rise time spec was in

the row for fall times and vice versa. They were labeled correctly, so the error was obvious.......................... 18

• Add "Using Front End EADCs" to the bullet describing the digital comparators...............................................38

• Remove pin numbers from table, as they were unnecessary and only applied to 64 pin package. Add note

that Global I/O settings travel with the pin and don't move when the IOMUX register moves the pin function to

another pin. ......................................................................................................................................................45

• Changed temperature sensor ADC channel from 15 to 14 ..............................................................................47
