VGH Block Function - continued

Application Example for VGH (3

rd Stage Positive Charge Pump)

Depending on the circuit construction, output voltage range of Charge Pump can be limited.

Besides, increasing VGH negative current can lower the possible output voltage.

Please consider the actual application need to select appropriate circuit construction.

Below Figure shows the circuit construction of 3

rd Stage Positive Charge Pump.

Under this circuit, the possible setting range of VGH output voltage is (AVDD + 2) V to ( AVDD x 3 - 2 ) V.

(When VGH negative current is 0mA)

Application Example for VGH (2

nd Stage Positive Charge Pump)

Below Figure shows the circuit construction of 2

nd Stage Positive Charge Pump.

Under this circuit, the possible setting range of VGH output voltage is (AVDD + 1) V to (AVDD x 2-1) V

(When VGH negative current is 0mA)
