HCNW4506 Gate Drive Interface Optocoupler IC

HCNW4506 is a logic output optocouplers. The HCNW4506 includes an AlGaAs LED. The LED is optically coupled to an integrated high-gain photodetector. Because of the reduced propagation delay difference between devices, this optocoupler is an excellent solution for improving inverter efficiency through reduced switching dead time.
By shorting output pins 6 and 7, an on-chip 20 k ohm output pull-up resistor can be enabled, removing the need for an external pull-up resistor in common IPM Applications.

Features:

• Performance specified for common IPM Applications over industrial temperature range: -40C to 100C
• Fast maximum propagation delay (PHL)= 480 nstPLH = 550 ns
• Minimized Pulse Width Distortion (PWD) = 450 ns
• 15 kV/s minimum common-mode transient immunity at VCM = 1500 V
• CTR > 44% at IF = 10 mA

Applications

• IPM isolation
• Isolated IGBT/MOSFET gate drive
• AC and brushless DC motor drives
