New NEC BiCMOS Optocouplers - Optimized for IGBT and MOSFET IsolationNEC's PS9552 Gate Drive Optocouplers Provide Superior Protection/Isolation from |
 Motor drive applications demand higher voltages and current than most ICs and microcontrollers can handle. To address the problem a variety of new IGBT and MOSFET drivers have been developed. These drivers depend on the galvanic isolation that NEC optocouplers provide to protect their microcontrollers from the power surges, ground loops, and electrical noise their motors generate. NEC's new PS9552 Series Optocouplers feature high common mode transient immunity, large peak output current, and fast switching speeds. Under Voltage Lockout Protection (UVLO) is also a standard feature, plus all PS9552 devices are housed in special RoHS-compliant white epoxy packages designed to limit heat absorption in high current applications. |
