(2) Electronic potentiometer
The electronic potentiometer function can be used when the voltage adjustment circuit is activated by the Power Control
Set command.
The electronic potentiometer adjusts the reference voltage using a resistor divider. This adjustment is set using the
Electronic Potentiometer Mode Set command and the Electronic Potentiometer Register Set 2-Byte command. Table 10
lists the correspondence between the 6 bits of setting data specified by these commands and the value of the
α
parameter.
(3) Voltage adjustment using the internal resistor
The internal voltage adjustment resistor can be used when the IRS pin is high. Here, the VR pin should be left open. The
internal resistor ratio (1 + Rb/Ra) can be set with the V
1
Adjustment Internal Resistor Ratio Set command.
Table 11 lists the correspondence between the 4 bits of data specified by this command and the value of the ratio (1 +
Rb/Ra) set by that command. See the section “V
1
voltage Adjustment Internal Resistor Ratio Set Command” in the
command descriptions for details on using this command.
(4) Voltage adjustment using external resistors
When the IRS pin is low, the built-in voltage adjustment resistor is disconnected and the voltage can be adjusted using
external resistors. Divide the voltage between V
DD
and V
5
with the external resistors Ra' and Rb' and apply that voltage
to the V
R
pin.
