Texas Instruments provides a recommended layout and placement guide in the TPS3838 datasheet, which includes guidelines for component placement, routing, and thermal considerations. Additionally, the TI website has a PCB thermal calculator tool that can help with thermal design.
The TPS3838 datasheet provides a resistor selection guide, which includes formulas and tables to help choose the correct resistor values based on the desired reset threshold voltage and timeout period. TI also provides a TPS3838 resistor calculator tool on their website.
The TPS3838E18DBVTG4 has an absolute maximum rating of 6V on the VDD pin, and 7V on the input pins. Exceeding these ratings can cause permanent damage to the device.
The TPS3838E18DBVTG4 has a power-up reset function that ensures the output is in a reset state during power-up. During power-down, the output will remain in a reset state until the voltage on the VDD pin falls below the reset threshold voltage.
Yes, the TPS3838E18DBVTG4 is compatible with 5V systems. The device has a maximum operating voltage of 5.5V, and the reset threshold voltage can be set to a value compatible with 5V systems.
