TPL0102-100: Tpl0102-100: tpl0102, occasionally VDD and HA in the device internal short circuit

Part Number: TPL0102-100

In our design, it's like the upper circuit. In the application, the VCCD2V0_T of U439 is powered on first, and the LDO is started. The U439 is required to output 1.8V. After 5s, the VDD power of U440 is started (VCCD3V3_DEV). In practical application, the function can be realized, but the line will be out occasionally. The VDD and HA PIN of U440 TPL0102 are short-circuted inside the chip (pass-through resistance value is 11 ohms), and the output voltage of LDO U439 becomes 2.6V. We can't find the reason, please support and help. thank you
