Description:Applicable to Infrared Ray reflow, 245°C; Utilizing proprietary process technology to achieve high operating temperature up to 125°C; Guaranteed Current Transfer Ratio (CTR) specifications across full temperature range; > 5mm creepage and clearance distance; CTR at very low input current, IF; Excellent CTR linearity at high temperature; High isolation voltage regulated by safety agency, UL1577, 3750 VAC RMS for 1 min. and DIN EN/IEC60747-5-2 (pending approval); Compact half pitch, mini-flat, 4-pin package (
A 4-layer PCB with a solid ground plane and a separate power plane is recommended. Keep the input and output traces as short as possible and away from noise sources.
Ensure the input voltage is within the recommended range (4.5V to 5.5V) and the enable pin is properly biased (high or low) according to the application requirements.
The maximum current rating of the FODM8801CV is 1A, but it's recommended to derate the current to 0.8A for reliable operation.
Use a voltage regulator or a voltage supervisor to ensure the input voltage remains within the recommended range. Add overvoltage protection (OVP) and undervoltage protection (UVP) circuits if necessary.
Use a heat sink or a thermal pad to dissipate heat. Ensure good airflow around the device and avoid blocking the thermal pads. Follow the recommended thermal design guidelines.
