ATT1800AT1

ATT1800AT1 is an optically coupled,photovoltaic generator with intergrated switching speed enhancement circuitry.It is constructed by using a GaAIAs LED for actuation control and a monolithic output control die containing a photodiode array (PDA),high speed turn-on/off circuitry and a robust ESD protection zener diode.

There are some features as follows.First is fast turn on.The second is fast turn off.Then is  rise times typically 500 ns.Next is fall times typically 300 ns.The fifth is 3750 Vrms I/O isolation voltage.The sixth is zener diode protection for external MOSFET.The last one is high output breakdown voltage (300 V).The typical applications include high speed solid-state relays,switch mode power supplies,DC motor control,industrial controls,ATE and isolated switching.

What comes next is about the absolute maximum ratings (at 25 unless otherwise specified).The T_A (ambient operating temperature range) is from -55 to +100.The T_stg (storage temperature range) is from -55 to +150.The T_S (pin soldering temperature (t=10 s max)) is 260.The V_ISO (input/output isolation voltage) is 3750 Vrms.The R_ins (insulation resistance) is >10 G at V_ISO=500 V,T_A=25 and is >0.1 G at V_ISO=500 V,T_A=100.Then is about the LED input ratings.The V_R (reverse voltage (I_R<10A)) is 6 V.The I_F (continuous forward current) is 60 mA.The IF_peak (peak forward current) is 600 mA.The P_DISS (power dissipation) is 100 mW.Next is about the MOSFET driver output ratings.The V_B (bias voltage (pin 5 to 6)) is 300 V.The leakage current (pin 5 to 6) is 200 nA at V_R=100 V.The peak input current (pin 5 to 4) is 50 mA.The P_DISS (power dissipation) is 150 mW.
