Description
General part information
DS1842 Series
The DS1842 integrates the discrete high-voltage components necessary for avalanche photodiode (APD) bias and monitor applications. A switch FET is used in conjunction with an external DC-DC controller to create a boost DC-DC converter. A current clamp limits current through the APD and also features an external shutdown. The device also includes a dual current mirror to monitor the APD current.ApplicationsAPD BiasingGPON Optical Network Unit and Optical Line Transmission
