The input side operates from a single • Split Outputs to provide 2.5-A Peak Source and 2.25-V to 5.5-V supply. The output side allows for a 5-A Peak Sink Currents supply range from minimum 15-V to maximum 30-V. Two complementary CMOS inputs control the • Short Propagation Delay: 76 ns (Typ), output state of the gate driver. The short propagation 110 ns (Max) time of 76 ns assures accurate control of the output • 2-A Active Miller Clamp stage. • Output Short-Circuit Clamp An internal desaturation (DESAT) fault detection • Soft Turn-Off (STO) during Short Circuit recognizes when the IGBT is in an overcurrent • Fault Alarm upon Desaturation Detection is condition. Upon a DESAT detect, a Mute logic Signaled on FLT and Reset Through RST immediately blocks the output of the isolator and initiates a soft-turn-off procedure which disables, • Input and Output Under Voltage Lock-Out (UVLO) OUTH, and pulls OUTL to low over a time span of with Ready (RDY) Pin Indication 2 μs. When OUTL reaches 2 V with respect to the • Active Output Pull-down and Default Low Outputs most negative supply potential, VEE2, the gate driver with Low Supply or Floating Inputs output is pulled hard to VEE2 potential turning the • 2.25-V to 5.5-V Input Supply Voltage IGBT immediately off. • 15-V to 30-V Output Driver Supply Voltage When desaturation is active, a fault signal is sent across the isolation barrier pulling the FLT output at • CMOS Compatible Inputs the input side low and blocking the isolator input. • Rejects Input Pulses and Noise Transients Mute logic is activated through the soft-turn-off Shorter Than 20 ns period. The FLT output condition is latched and can • Operating Temperature: –40°C to 125°C Ambient be reset only after RDY goes high, through a low- • Surge Immunity 10000-VPK (according to IEC active pulse at the RST input. 61000-4-5) Device Information(1) • Safety and Regulatory Certifications: PART NUMBER PACKAGE BODY SIZE (NOM) – 8000-VPK VIOTM and 1420-VPK VIORM ISO5452 SOIC (16) 10.30 mm × 7.50 mm Reinforced Isolation per DIN V VDE V 0884-10 (1) For all available packages, see the orderable addendum at (VDE V 0884-10):2006-12 the end of the datasheet. – 5700-VRMS Isolation for 1 Minute per UL 1577 – CSA Component Acceptance Notice 5A, IEC Functional Block Diagram 60950-1, IEC 60601-1 and IEC 61010-1 End Equipment Standards – CQC Certification per GB4943.1-2011 – All Certifications are Planned 2 Applications • Isolated IGBT and MOSFET Drives in – Industrial Motor Control Drives – Industrial Power Supplies – Solar Inverters – HEV and EV Power Modules – Induction Heating 1 An IMPORTANT NOTICE at the end of this data sheet addresses availability, warranty, changes, use in safety-critical applications, intellectual property matters and other important disclaimers.
