IR53H(D)420Recommended Operating Conditions The input/output logic timing diagram is shown in figure 1. For proper operation, the device should be used within the recommended conditions. Symbol DefinitionMinimumMaximumUnits VB High side floating supply absolute voltage Vo + 10 Vo + Vclamp V V IN High voltage supply — 500 VO Half-bridge output voltage -3.0 (note 3) 500 ID Continuous drain current (TA = 25°C) — 0.7 -P2 — 0.85 (TA = 85°C) — 0.5 A -P2 — 0.6 (TC = 25°C) -P2 — 1.2 ICC Supply current (note 3) 5 mA TA Ambient temperature -40 125 °C NOTE 2: Care should be taken to avoid switching conditions where the VS node flies inductively below ground by more than 5V. NOTE 3: Enough current should be supplied to the VCC lead of the IC to keep the internal 15.6V zener diode clamping the voltage at this lead. Electrical Characteristics VBIAS (VCC, VBS) = 12V, CT = 1 nF and TA = 25°C unless otherwise specified. The VIN, VTH and IIN parameters are referenced to COM.
