Advance Information
Solid State Relay for Automotive
Flasher Applications
This device is a Dual High Side Power Switch dedicated for automotive flasher
applications. In comparison with mechanical solutions, this device offers higher
reliability as well as protection and diagnostic features.
The device consists of two 25m鈩?Rdson fully protected high side switches, in a
surface mount power package. It interfaces directly with a microcontroller and
includes a current recopy function in order to allow the detection of a failed lamp in
the application.
