Description

The U426B is an IR-driver IC for IR data communication. The circuit contains a programmable constant current source (DRV) to drive the IRED. The current is programmed by an external resistor (RS). With the internal comparator (COMP) an external voltage can be monitored. The low-power standby mode, controlled by means of the WAKE input, makes the U426B well suited for battery- powered systems.
