2 / 16 page IR22771S/IR21771S(PbF) 2 www.irf.com Absolute Maximum Ratings Absolute Maximum Ratings indicate sustained limits beyond which damage to the device may occur. All voltage parameters are absolute voltages referenced to VSS; all currents are defined positive into any lead. The Thermal Resistance and Power Dissipation ratings are measured under board mounted and still air conditions. Symbol Definition Min. Max. Units IR22771 - 0.3 1225 V VB High Side Floating Supply Voltage IR21771 - 0.3 625 V VS High Side Floating Ground Voltage VB - 25 VB + 0.3 V Vin+ / Vin- High-Side Inputs Voltages VB - 5 VB + 0.3 V G0 / G1 High-Side Range Selectors VB - 0.3 VB + 0.3 V VCC Low-Side Fixed Supply Voltage - 0.3 25 V Sync Low-Side Input Synchronization Signal - 0.3 VCC + 0.3 V PO PWM Output - 0.3 VCC + 0.3 V OC Over Current Output Voltage - 0.3 VCC + 0.3 V dVS/dt Allowable Offset Voltage Slew Rate 50 V/ns PD Maximum Power Dissipation 250 mW RthJA Thermal Resistance, Junction to Ambient 90 ºC/W TJ Junction Temperature -40 125 ºC TS Storage Temperature -55 150 ºC TL Lead Temperature (Soldering, 10 seconds) 300 ºC Recommended Operating Conditions For proper operation the device should be used within the recommended conditions. All voltage parameters are absolute voltages referenced to VSS. The V S offset rating is tested with all supplies biased at 15V differential. Symbol Definition Min. Max.
