Type: Schematic Change
Reason: BOM Optimization.
Impact: None. Minor changes in electrical characteristics.
#3 Changed load switch TPS27081ADDCR (Q1) to MP5077GG-Z and adapted circuit.
Type: Schematic Change
Reason: BOM Optimization.
Impact: None. Increased current output capability. Minor changes in electrical characteristics.
#3 Added power supervisor STM6710LWB6F (U12, U13) and connected System controller (U3) pin 25 to net "PG_SENSE" instead of 3.3 V.
Type: Schematic Change

#11 Connect U14 to I2C bus via resistors (R91, R92) and pull-up resistors (R45, R47).
Type: Schematic Change
Reason: Improvement of DCDC handling.
Impact: None. I2C bus has additional device.
#5 Added pull-up resistor (R71) for signal "SPI_DQ2".
Type: Schematic Change

Type: BOM Change
Reason: EOL of component.
Impact: None.
#20 Signal trace lengths changed
Type: PCB change
Reason: Result of changes above.
Impact: Changed trace length have to be taken into account in existing designs. The trace length for new revision will be available in TE0713 series pinout generator. Please check if change in trace length still matches your requirements. Adaption of carrier may be necessary.
#5 Added common mode voltage setting via resistors (R62, R64, R65, R66) for clock signals "PLL_CLK_P" and "PLL_CLK_N" termination.
Type: Schematic Change
