Hardware Guide
Figure 3-2 Recommended power circuit of MU609 module
When the system power restarts, a discharge circuit is recommended to make sure
the power voltage drops below 1.9 V for 1s at least.

3.3.3 Output Power Supply Interface

Output power supply interface is VCC_EXT1.
Through the output power supply interface, the MU609 module can supply 1.8 V
power externally with an output current of 10 mA (typical value) for external level
conversion or other applications.
If the MU609 module is in sleep mode, the output power supply interface is in the low
power consumption state (< 500 μA). If the MU609 module is in power down mode,
the output power supply is in the disabled state.
