provides a temperature gradient to the reference voltage. There are three types of temperature gradients and
the appropriate one is selected by a signal sent from the temperature gradient selection circuit. The voltage
stabilizer stabilizes boosting output voltage V
output voltage can be set to any voltage between the reference voltage V
external resistor R
at timings when the signal is sent from the system (microprocessor, etc.).

Voltage converters (I) and (II) perform double boosting and triple boosting for input power voltage V
For double boosting, the double input voltage V
Fig.4.3 and 4.4 show the relationships between input and output voltages, using V
Note 1) In triple boosting, the double boosting output (-10V) cannot be obtained from the CAP2- pin.
Note 2) When connecting to the system power, CAP2- = -5V is obtained for double boosting output and
The reference voltage generator generates a reference voltage required to operate the voltage stabilizer, and
The voltage stabilizer, which is equipped with the power-off function, enables V
