Power Supply
Do not power up the FM515 until it is properly connected. Be sure the power is cut off before connecting a cable to or
disconnecting a cable from the host interface connector. Hot-plugging could damage the scanner.
Unstable power supply or sharp voltage drops or unreasonably short interval between power-ons may lead to unstable
performance of the scanner. Do not resupply the power immediately after cutting it off.
1. When designing, the user should ensure that the input power of FM515 is fully decoupled. It is recommended to place a
22uF and a 100nF X5R or X7R ceramic capacitor beside the power input pin on the connector which is soldered on the board.
2. Ensure that the input power drops below 0.5V before powering the FM515 on again, otherwise it will lead to abnormal
function.
Ripple Noise
To ensure the image quality, a power supply with low ripple noise is needed.
Acceptable ripple range (peak-to-peak)
≤
VCC*5%
