Function Description

6.1 Generate Hi-V Driving Bias Supply

6.1.1 Internal Charge Pump Supply

The charge pump circuit can generate Hi-voltage up to 30V. User also can select 0V, 15V or 30V to drive EPD

by setting control register.

The value of Hi-voltage that pump can generate as following.

VPP=30V, VX5=15V, VSS=0V, set register #10h bit5 VPP15=0
