6. Design guide
6.1. Application circuit
It is recommended to add an anti-static protection IC to the power input.
Figure 7 Application circuit schematic
6.2. Power supply
 Recommended 3.3V-4.5V voltage, peak current above 500mA
 It is recommended to use LDO for power supply; if using DC-DC, it is
recommended that the ripple be controlled within 50mV.
 For the DC-DC power supply circuit, it is recommended to reserve a place for the
dynamic response capacitor to optimize the output ripple when the load changes
greatly.
 It is recommended to add ESD devices for the 3.3V-4.5V power interface.
