INTEGRATED FUNCTIONS AND FEATURES
• 3-phase IGBT inverter bridge configured by the latest 3rd. generation IGBT and diode technologies.
• Circuit for dynamic braking of motor regenerative energy.
INTEGRATED DRIVE, PROTECTION AND SYSTEM CONTROL FUNCTIONS:
• For P-Side IGBTs : Drive circuit, High voltage isolated high-speed level shifting, Short-circuit protection (SC),
Bootstrap circuit supply scheme (Single drive-power-supply) and Under voltage protection (UV).
• For N-Side IGBTs : Drive circuit, Short circuit protection (SC), Control-supply Under voltage and Over voltage protection (OV/UV), System Over-temperature protection (OT), Fault output (FO) signaling circuit, and Current-Limit warning signal output (CL)
• For Brake circuit IGBT : Drive circuit
• Warning and Fault signaling :
FO1 : Short circuit protection for lower-leg IGBTs and Input interlocking against spurious arm shoot-through.
FO2 : N-side control supply abnormality locking (OV/UV)
FO3 : System over-temperature protection (OT).
CL : Warning for inverter current overload condition
• For system feedback control : Analogue signal feedback reproducing actual inverter phase current (3φ).
• Input Interface : 5V CMOS/TTL compatible, Schmitt trigger input, and Arm-Shoot-Through interlock protection.
APPLICATION
