INTEGRATED DRIVE, PROTECTION AND SYSTEM CONTROL FUNCTIONS:

• For P-Side IGBTs : Drive circuit, High-speed photo-couplers, 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 signaling circuit (Fo), 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 output phase current (3φ).

• Input Interface : 5V CMOS/TTL compatible, Schmitt trigger input, and Arm-Shoot-Through interlock protection.
