Littelfuse has introduced an optically isolated photovoltaic gate driver for mosfets and IGBTs. Essentially, photovoltaic gate drivers are opto-isolated relays without the internal output mosfets, ...

The circuit was designed to provide a voltage over and under the specified value with the use of a switch that will be operated by a relay. LM741 – a general purpose single operational amplifier with ...

Modern active components, such as A/D and D/A converters and operational amplifiers, typically don’t require a negative supply voltage. Op amps in particular are available with rail-to-rail inputs and ...
