Battery voltage detection circuit
The M61040 battery voltage detection circuit is shown in figure 5.
This circuit is composed of switch, buffer amplifier, reference voltage section and logic circuit.
Microcomputer selects detecting voltage before logic circuit controls the connection of switches.
This connection decides which cell voltage(Vbat1,Vbat2,Vbat3,Vbat4) should be output from Analog
out pin. Besides offset voltage can be output.
In Power Down mode, supply current in this block is close to zero because all switches are off.
NOTE:
Regard 50
μ
s as the standard of settling time by voltage change in this block.
