QS5Y2FSTR Frequently Asked Questions (FAQ)

  • ROHM recommends a 4-layer PCB with a solid ground plane and a separate power plane for the IC. Keep the input and output traces short and away from each other to minimize noise and crosstalk.

  • The QS5Y2FSTR requires a stable voltage supply and proper biasing. Ensure the input voltage is within the recommended range (4.5V to 5.5V), and the bias resistors are correctly sized to provide a stable operating point.

  • The QS5Y2FSTR is rated for operation from -40°C to +125°C. However, it's essential to consider the derating curves and thermal management to ensure reliable operation within the specified temperature range.

  • ROHM recommends using ESD protection devices, such as TVS diodes or ESD arrays, on the input and output pins to protect the IC from electrostatic discharge. Follow proper PCB design and layout guidelines to minimize ESD risks.

  • Store the QS5Y2FSTR in a dry, cool place (below 25°C and 60% RH) away from direct sunlight and moisture. Avoid exposing the IC to extreme temperatures, humidity, or physical stress during storage.
