ASSR-V621-302E

The ASSR-V621-302E is a 2-channel SMD Photovoltaic MOSFET Driver specially designed to drive high power MOSFETs. It consists of an AlGaAs infrared light-emitting diode (LED) input stage optically coupled to an output detector circuit. The detector consists of a high-speed photovoltaic diode array and driver circuitry to switch ON/OFF two discrete high voltage MOSFETs externally. The relay driver turns ON (contact closes) with a minimum input current of 3mA through the input LED. The relay driver turns OFF (contact opens) with an input voltage of 0.8V or less. The 2-channel configuration allows 2 independent MOSFETs to be driven. It has the versatility to double the photovoltaic voltage by connecting the 2-channel in series or to double the short circuit current by connecting the 2-channel in parallel.
