Description:The PS9587, PS9587L1, PS9587L2 and PS9587L3 are optically coupled isolators containing a GaAlAs LED on the input side and a photo diode and a signal processing circuit on the output side on one chip. The PS9587L1 and PS9587L2 are designed specifically for long creepage-distance as well as high common mode transient immunity (CMR) and High-Speed digital output type. Consequently, they are suitable for High-Speed logic interface that needs long creepage-distance (8 mm) on mounting. The PS9587L1 is lead bendin
Renesas provides a recommended PCB layout guide in their application note (APN) document, which includes thermal design considerations, such as thermal vias, copper pours, and component placement.
Renesas recommends following the thermal design guidelines, using a heat sink, and ensuring good airflow around the device. Additionally, the device has built-in thermal protection, which will shut down the device if the junction temperature exceeds 150°C.
Although the datasheet specifies the recommended operating voltage range, the absolute maximum rating for the input pins is typically 7V, as stated in the device's reliability report or other supporting documentation.
Yes, the PS9587L2-AX is AEC-Q100 qualified, which means it meets the automotive industry's standards for reliability and performance. However, it's essential to follow the specific requirements and guidelines for automotive applications, such as those outlined in the AEC-Q100 standard.
Renesas provides a troubleshooting guide for I2C interface issues in their application note (APN) document, which includes steps for debugging, such as checking the clock frequency, signal integrity, and slave address configuration.
