PS9821-2-AX - Renesas Electronics

Description: The PS9821-1 and PS9821-2 are active-low type high-speed photocouplers that use a GaAlAs light-emitting diode on the input side and a photodetector IC that includes a photodiode and a signal processor on the same chip on the output side. The PS9821-1, -2 are designed specifically for high common mode transient immunity (CMR) and low pulse width distortion, PS9821-2 is suitable for high density applications.

PS9821-2-AX Frequently Asked Questions (FAQs)

  • A 4-layer PCB with a solid ground plane and a separate power plane is recommended. Keep the analog and digital sections separate, and use a common ground point for the analog and digital grounds.
  • Use a metal shield around the device, and ensure that the PCB layout is designed to minimize radiation. Follow the recommended layout guidelines and use a common mode choke to reduce emissions.
  • The PS9821-2-AX is rated for operation from -40°C to 85°C. However, the device can be operated at temperatures up to 105°C for short periods, but this may affect its reliability and lifespan.
  • The POR and BOR functions are enabled by default. To disable them, tie the POR and BOR pins to VCC. Ensure that the power supply is stable and within the recommended voltage range to prevent unwanted resets.
  • The recommended clock frequency is 24 MHz, and the clock source can be either an external crystal oscillator or an external clock signal. Ensure that the clock signal is stable and within the recommended frequency range.
