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=82Kâ¦, when VDD=5V; Rosc=100Kâ¦, 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)
