BS-8210 Base Unit
This section explains the block diagram and the functions of the BS-8210 Base Unit.
BASE-CPU Board (PCB-7506) Circuit Description
BASE-CPU Board selects the power supply to be used from the AC power supply unit or the
battery.
It also charges the specified battery (BTO-008), communicates with external devices, monitors the
voltage, and controls the fan during battery charging.
CPU
The CPU controls power supply IC/charge IC, communicates with the Lithium-ion Battery Pack,
and performs communication/control processing of external devices. FLASH MEMORY, Timer and
SCI (Serial Communication Interface) are incorporated.
Charge Controller
Controls charge of the BTO-008 Lithium-ion Battery Pack. The rapid charge (during standby) and
normal charge (during operation) are switched depending on the state of the main unit. Voltage
/current protection in the Battery Pack is provided as well as overvoltage protection on the
BASE-CPU Board and protection by software/hardware timer.
It also switches the power supply to be used between the AC power supply unit and the battery.
The power will be supplied to the HSB-80 HS Adapter without step-up/down. The priority of the
power supply is “AC power supply unit > Li-ion battery”.
Board Power Supply (DC/DC converter, series regulator)
Receives the power supply from the AC power supply unit or the Li-ion battery, and generates the
power voltage to be used inside the board or external devices.
