Preliminary Technical Data
ADE7169F16
POWER MANAGEMENT
The ADE7169F16 has an elaborate power management
circuitry that manages the regular power supply to Battery
switch over and power supply failures. The power management
functionalities can be accessed directly through the 8052 SFR –
see Table 11.
