Units VB High Side Floating Supply Voltage -0.3 625 VS High Side Floating Offset Voltage VB - 25 VB + 0.3 VHO High Side Floating Output Voltage VS - 0.3 VB + 0.3 VCC Logic Supply Voltage -0.3 25 V VIN Logic Input Voltage -0.3 VCC + 0.3 VFLT FAULT Output Voltage -0.3 VCC + 0.3 VCS Current Sense Voltage VS - 0.3 VB + 0.3 dVs/dt Allowable Offset Supply Voltage Transient — 50 V/ns PD Package Power Dissipation @ TA ≤ +25°C (8 Lead DIP) — 1.0 (8 Lead SOIC) — 0.625 RthJA Thermal Resistance, Junction to Ambient (8 Lead DIP) — 125 (8 Lead SOIC) — 200 TJ Junction Temperature — 150 TS Storage Temperature -55 150 TL Lead Temperature (Soldering, 10 seconds) — 300 Absolute Maximum Ratings Absolute Maximum Ratings indicate sustained limits beyond which damage to the device may occur. All voltage param- eters are absolute voltages referenced to COM. The Thermal Resistance and Power Dissipation ratings are measured under board mounted and still air conditions. Symbol Definition Min. Max. Units VB High Side Floating Supply Voltage (IR2127/IR2128) VS + 12 VS + 20 (IR21271) VS + 9 VS + 20 VS High Side Floating Offset Voltage Note 1 600 VHO High Side Floating Output Voltage VS VB VCC Logic Supply Voltage 10 20 VIN Logic Input Voltage 0 VCC VFLT FAULT Output Voltage 0 VCC VCS Current Sense Signal Voltage VS VS + 5 TA Ambient Temperature -40 125 °C Note 1: Logic operational for VS of -5 to +600V. Logic state held for VS of -5V to -VBS. (Please refer to the Design Tip DT97-3 for more details). Recommended 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. The VS offset rating is tested with all supplies biased at 15V differential. °C/W W °C V |
