Note:
Since the product contains capacitors at the input, inrush current will occur during
power-on. Evaluate in the actual environment in order to check the effect of the supply voltage
drop due to the inrush current.

3. Hardware Integration Guide
3.1 Design Notes
For the normal operation of UB4B0M, the following signals need to be connected
correctly:
The module VCC power-on behavior is repeatable, the initial level is lower than
0.4V, and the undershoot and ringing should be guaranteed to be within 5% VCC
