Figure 6: Block Diagram of ACPL-337J and SO-16 Package
The ACPL-337J is a fully featured 4A smart gate drive optocoupler device capable of driving 600V, 650V, or 1200V, up to
200A IGBT directly. The device features rail-to-rail output, integrated LED driver, active Miller clamp, high desaturation
(DESAT) blanking current source, and Under Voltage Lock-Out (ULVO) feedback control circuit, providing a complete
cost-effective gate drive solution for motor control and power inverter applications. The ACPL-337J is available in a compact,
surface-mountable SO-16 package with 8 mm of creepage and clearance. It provides the reinforced insulation certified by
safety regulatory IEC/EN/DIN, UL, and CSA with working voltage of V = 1414V .

Figure 7: ACPL-337J Gate Drive Circuit
The schematic shows the gate drive design for the top bridge, U-phase IGBT using ACPL-337J (IC3). Other phases (V and
W), bottom bridge, and braking IGBTs use the same gate drive circuits.
