PT6324

16-GRID X 24-SEGMENT VFD APPLICATION CIRCUIT

Notes:

1. The value of Rosc is depend on PT6324 IC chip supply voltage of VDD (Rosc=82KΩ, when VDD=5V; Rosc=100KΩ, when VDD=3.3V).

2. Z1, Z2=Zener diode 5.1V

3. Please adding the current amplifying circuit as following figure when IOHGR>15mA on VFD panel for high brightness issue.

*=C.A. Circuit=Current amplifying circuit

C.A. Circuit-1 & C.A. Circuit-2 Ex.:

Parts recommended:

• Q=SAMSUNG-KSR1105 (General fast switching transistor)

• D=HITACHI-HSM221C (General fast recovery diode)
