Infineon Technologies Solid state isolators

The advanced solid-state isolator family provides powerful energy transmission over a galvanic isolation barrier to drive the gates of MOS-controlled power transistors, such as CoolMOS™, OptiMOS™, TRENCHSTOP™ IGBT, or CoolSiC™. The output side of the solid-state isolator family does not require a dedicated voltage supply to drive the power transistor's gate, offers advanced control functions such as fast turn -on/off, overcurrent protection and over-temperature protection to easily and safely build up solid-state relays for various applications.

Key features

• Integrated isolated gate bias supply for gate driving
• High-impedance, CMOS input
• Fast turn-on and turn-off for safe switches' safe operating area (SOA) operatio
• High output peak current of 185 µA (direct drive variants) or 400 mA (buffered variants)

Additional features

• High output voltage up to 18 V - no series / parallel configuration required for powerful gate driving
• Temperature sensor and current sensor protection inputs
• Dynamic Miller clamping protection
• Wide-body package with high creepage and clearance for UL 1577 / IEC 60747-17

Applications

• Solid-state relay AC and DC applications
