Renesas Electronics announced the availability of two new high-performance optocouplers – the PS9324 and the PS9123 – for industrial and motor control applications. The high-speed devices are designed for 10 Mbps operation over an extended temperature range: between -40°C and 100°C for the PS9123 and up to 110°C for the PS9324. The ICs comply with international safety standards such as UL, CSA and VDE (optional), making them suited for applications in harsh industrial environments such as factory automation, measurement equipment and motor control.
The detector IC of the active low type PS9324 series features an open collector output and low operation voltages from 2,7 V to 5,5 V, allowing flexible circuit design. A communication speed of 10 Mbps can be achieved due to the specified maximum propagation delay times of 75 ns at 25°C and typical values of 40 ns. The PS9123 series comes with a totem pole output, offering shorter propagation delay times as low as 65 ns (max) at 25°C. The maximum pulse width distortion is less than 35 ns for the PS9324 series and less than 50 ns for the PS9123 series.
For operation in noisy industrial environments, Renesas’ new optocouplers have an internal shield providing a common-mode transient immunity (CMTI) of minimum 15 kV/μs and typical values of 20 kV/μs.
The PS9324 comes in a small 6-pin shrink dual inline package (SDIP). The small package reduces the mounting space by 50% compared to a classical 8-pin DIP package while guaranteeing the highest isolation voltage of 5 kVrms and achieving a minimum creepage distance of 8 mm (PS9324L2). The PS9123 is delivered in a 5-pin small outline package (SOP), with a minimum pin-to-pin distance of 1,27 mm, allowing space saving designs.
