5 / 9 page PDE-3063-0 ECN3063 6. Standard Application Component Recommended Value Usage Remark C0 More than 0.22 µF for inner power supply(VB). stress voltage is VB C1,C2 0.5 µF ± 20% for charge pump stress voltage is VCC D1,D2 Hitachi DFG1C6 (glass mold) Hitachi DFM1F6(resin mold) or considerable parts for charge pump 600V/1.0A trr ≤100ns CTR 1800 pF ± 5% for clock Note 1. RTR 22 k Ω ± 5% for clock Note 1. Rs Note.2 Overcurrent limit Note 1. Clock frequency is determined approximately by next equation. Floating capacitance of PCB must be considered. At Recommended Value of CR, the error factor of IC is about 10%. fclock = -1 / (2C*R*Ln(1-3.5/5.5)) ; Ln is natural logarithm = 0.494 / (C*R) (Hz) Note 2. Current is limited by the following equation. IO = Vref / Rs (A) Clock GH1 GL VTR CR UT VT WT UB VB WB VCC VS2 CL C- C+ CB D2 D1 C1 C2 + + - - RS CTR RTR VB MU MV MW VCC(15V) Vref VS Top Arm Driver Pulse Generator VB supply Charge Pump Microprocessor Motor VS1 GH2 C0 CLOCK RS Vref 0.5V Latch + – Filter 1 µs R S Bottom Arm Driver |
