    PhotoMOS Relays In previous articles, we've shown how a PhotoMOS works, and how to optimize certain characteristics. Here, we talk about the balance between Output Capacitance  and On-resistance (C vs R).

    PhotoMOS Relays In the last PhotoMOS blog post, we discussed how to select the correct capacitor for the application. Now we'll move on to switching time. Minimizing Turn-on Time There are some cases where turn-on time is crucial, and the circuit designer must find ways to reduce the amount of time it takes from applying the LED forward current, until the MOSFET gate is closed. Typically, higher LED current will lead to faster switching time. On the other hand, it will increase power consumption and reduce the LED life.

    PhotoMOS Solid State Relays In an earlier blog post, we described the principle of operation of a PhotoMOS solid state Relay. Now we'll look at some considerations when designing the circuit around the PhotoMOS.

    PID Tuning Tuning a control loop, or PID, is the adjustment of its control parameters (gain/proportional band, integral gain/reset, and derivative gain/rate) to the optimum values for the desired control response. Stability, or bounded oscillation, is a basic requirement, however different systems have different behavior, different applications have different requirements, and requirements may conflict with one another.

    PhotoMOS With Short Circuit Protection  Small size, reliability and low power consumption are the requirements for components used to switch signal outputs in sensors, control units or on measurement cards. An important function is the galvanic isolation of sensitive electronics from possible disturbances on the output side, e.g. voltage peaks or overcurrents, which can arise due to short circuits or improper use. Panasonic's new short-circuit protected PhotoMOS Relay family is optimally prepared to meet these challenges.
