without causing any problem. In this case, because the charge pump voltage drops, increase the
capacitance of the capacitor connected to the CPV pin. However, this will cause the charging current to the
capacitor and, hence, loss in the IC to increase. Therefore be careful not to exceed the allowable loss.

hours at a temperature and humidity of 30°C and 60% RH or less. Because the device is emboss-taped
and cannot be processed by baking, always be sure to use it within the said allowable time after unpacking.
Standard tape packing quantity: 2000 devices / reel (EL1).
Feeding the charge pump voltage to external devices
Shorting between outputs, short-circuit of outputs and V
cause the IC to break down. Therefore, pay careful attention to the design of output lines and V
GND lines.

Precautions on dry packing
Current can be taken out of the final stage (CPV pin) of the charge pump and fed to external devices
Because this IC contains a charge pump function, loss in it affects external capacitor capacitance and
For arm-shorting input logic, all outputs (UU, VU, WU, UB, VB and WB) are pulled low. When
