9 Typical Application Circuit
Note:1/ when I2C are idle mode,SDA and SCL must be connect to high level(by pull up
resistor),otherwise the device maybe can not go into power saving mode.
2/ In power-saving mode, SCL frequency must be less than 21KHz.
3/ Work at 1/3 bias, Vdd – Vlcd must be more than 2.9V。
