Optocoupler Ic

Product Details:

he HCPL-3120 contains a GaAsP LED while the HCPL­­J312 and the HCNW3120 contain an AlGaAs LED. The LED is optically coupled to an integrated circuit with a power output stage. These optocouplers are ideally suited for driving power IGBTs and MOSFETs used in motor control inverter applications. The high operating voltage range of the output stage provides the drive voltages required by gate controlled devices. The voltage and current supplied by these optocouplers make them ideally suited for directly driving IGBTs with ratings up to 1200 V/100 A. For IGBTs with higher ratings, the HCPL-3120 series can be used to drive a discrete power stage which drives the IGBT gate. The HCNW3120 has the highest insulation voltage of VIORM=1414Vpeak in the IEC/EN/DIN EN 60747-5-2. The HCPL-J312 has an insulation voltage of VIORM=891Vpeak and the VIORM=630Vpeak is also available with the HCPL-3120 (Option060).

Product Details:

The HCNR200/201 high-linearity analog optocoupler consists of a high-performance AlGaAs LED that illumi  nates two closely matched photodiodes. The input pho todiode can be used to monitor, and therefore stabilize, the light output of the LED. As a result, the non-linearity and drift characteristics of the LED can be virtually elimi nated. The output photodiode produces a photocurrent that is linearly related to the light output of the LED. The close matching of the photo-diodes and advanced de sign of the package ensure the high linearity and stable gain characteristics of the optocoupler. The HCNR200/201 can be used to isolate analog signals in a wide variety of applications that require good stabil ity, linearity, bandwidth and low cost. The HCNR200/201 is very flexible and, by appropriate design of the appli cation circuit, is capable of operating in many different modes, including: unipolar/bipolar, ac/dc and inverting/ non-inverting. The HCNR200/201 is an excellent solution for many analog isolation problems

Product Details:

The Broadcom® HCPL-22XX, HCPL-02XX, and HCNW22XX are optically coupled logic gates. The HCPL22XX and HCPL-02XX contain a GaAsP LED while the HCNW22XX contains an AlGaAs LED. The detectors have totem pole output stages and optical receiver input stages with built-in Schmitt triggers to provide logic-compatible waveforms, eliminating the need for additional waveshaping. A superior internal shield on the HCPL-2211/12, HCPL-0211, HCPL-2232, and HCNW2211 guarantees common mode transient immunity of 10 kV/µs at a common mode voltage of 1000V.
