PIN CONFIGUTION
優(yōu)勢替代
FEATURES
? Provides lossless ZC (Zero Crossing) signal to system MCU
? Meets IEC 60335 X capacitor discharge of <34 V in <1 sec
? One part to cover X capacitor values up to 6 mF
? Blocks current through X capacitor discharge resistors when
AC voltage is connected
? Automatically discharges X capacitors through discharge
resistors when AC is disconnected
? Simplifies EMI filter design – larger X capacitor allows smaller
inductive components with no change in consumption
? Only two terminals – meets safety standards for use before
or after system input fuse
? >4 mm creepage on package and PCB
? Self supplied – no external bias required
? High common mode surge immunity – no external ground
connection
? High differential surge withstand – 1000 V internal MOSFETs
? NEMKO and CB certification
