CPC1510 LED Forward Voltage Data Sheet Change Product Change Notification
■Detailed Description of Change：
●IXYS Integrated Circuits Division (ICD), now part of Littelfuse, has made design improvements to the CPC1510G that required a change to the product’s maximum LED Forward Voltage (VF) specification.
●Design improvements have been made to narrow the thermal shutdown activation trip point range. This will allow improved load current capability at the upper end of the operational ambient temperature range and improved product lifetime by reducing the maximum junction temperature seen by the device. To facilitate these improvements, it was necessary to upgrade the input LED with another from our portfolio of qualified LEDs having a higher efficiency.
●Because this higher efficiency LED has a slightly greater forward voltage rating, the maximum
“LED Forward Voltage“ specification in the CPC1510 data sheet will change from: 1.45V with IF=10mA to: 1.5V with IF=5mA.
■Reason for Change：
●These thermal shutdown circuit design improvements will result in enhanced performance and product reliability. This change is a result of our ongoing effort and commitment to continuous quality improvement of our products.
