Block Diagram Description
Battery Voltage Detection Circuit
The M61047FP battery voltage detection circuit is shown in Figure 3. 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 100
μ
s as the standard of settling time by voltage change in this block.
