HCNW4506-000E IC – Intelligent Power Module and Gate Drive Interface Optocoupler IC

The HCNW4506 contain an AlGaAs LED. The LED is optically coupled to an integrated high-gain photo detector. Minimized propagation delay difference between devices makes these optocouplers excellent solutions for improving inverter efficiency through reduced switching dead time. An on-chip 20 k? output pull-up resistor can be enabled by shorting output pins 6 and 7, thus eliminating the need for an external pull-up resistor in common IPM applications. Specifications and performance plots are given for typical IPM applications.

Features:

1. Performance specified for common IPM applications over industrial temperature range: -40℃ to 100℃.
2. Fast maximum propagation delays tPHL = 480 ns tPLH = 550 ns.
3. Minimized Pulse Width Distortion PWD = 450 ns.
4. 15 kV/?s minimum common mode transient immunity at VCM = 1500 V.
5. CTR > 44% at IF = 10 mA.
6. Safety approval: UL Recognized: -5000 V rms / 1 min. for HCNW4506.

Applications:-

1. IPM isolation.
2. Isolated IGBT/MOSFET gate drive.
3. AC and brushless DC motor drives.
4. Industrial inverters etc.
